Experience Booster

In Video Games, there are items, abilities, etc. that help players gain more Experience Points, especially when Level Grinding is a problem. Unlike with a Rare Candy, which gives experience immediately when consumed, an Experience Booster multiplies the amount you already gain e.g. from fighting or gives bonus experience under certain conditions. In most games that these appear in, experienced gamers will try to earn and equip these as soon as they can, since they can usually help raise all other stats more quickly.

Compare Leaked Experience (if it happens by default), Money Multiplier (which does this for loot), Random Drop Booster (which boosts the Random Drop rate). See also Luck Stat and Meta Power Up. Can be part of the strategy that makes a Peninsula of Power Leveling viable. Contrast Experience Penalty.

Video Game Examples

Action Adventure

• Afterimage: Some accessories (such as the Adventurer's Bracelet), outfits, armor pieces, or Talent nodes (such as Wisp of Wealth) boost your Experience Gain rate by a given percentage.
• In the Castlevania series:
  • There are items (and even soul abilities in Castlevania: Aria of Sorrow and Castlevania: Dawn of Sorrow) that have this effect. They are not that useful, however — level grinding isn't as important as having good weapons, abilities, and playing the games better.
  • Castlevania: Circle of the Moon: Venus + Cockatrice. Gains experience from walking... WALKING, not RUNNING, and you only gain 1 point every couple of steps. Running and jumping restarts the amount of steps you need to take for the gain to kick in again.
• In Singular Stone, there are items called "Accelerator" that doubles XP gained from killing enemies. Each character have their dedicated Accelerator, so you cannot swap it to other characters.
• In Too Human, as your combo meter raises you get extra xp (max of 3% at level 3 combo meter) Runes can also be fitted into weapons and armor that also boost the amount of xp gained (stackable up to a certain amount, unsure of the cap)

Beat Em Up

• Fairy Bloom Freesia: Freesia gets bonus experience based on how well she did in a stage.

Eastern RPGs

• Blue Dragon had the Black Belt item that increased XP gain.
• Breath of Fire III and IV have Ivory Dice, which, when used on a single target, multiplies its experience and zenny yield. It can be stacked until it reaches the battle experience cap of 65535. IV actually has a way of farming Ivory Dice (through a late-game Manillo Merchant).
• Dislyte: Esper XP Boosters can be bought from the Resources section at the Plaza and they double Esper XP. There are two versions, one that lasts for 8 hours while the other lasts for 24 hours.
• There is a Dragon Ball Z game, set during the Buu saga, which has RPG Elements. There are pieces of equipment that, when equipped, increase the Exp. you gain per kill, but decrease your walking speed.
• In Dragon Quest IX, the Armamentalist's Coup de Grâce gives a random experience boost to all party members. The Elevating Shoes, meanwhile, give a 5% bonus to anyone who wears them, a small but helpful boost due to the experience system awarding less to lower level characters, something that inevitably happens with characters under jobs with steeper leveling curves.
• In Dubloon, the order of characters in your party determines the amount of experience they gain from battles; the one at the tail receives the most.
• While Dungeon Siege has no experience points, items that artificially raised your skills and had you use them (like an axe that raised your melee skill) fulfilled the Experience Modifier role: having higher modified skill meant you landed more hits, and landing more hits raised the base skill value faster, and, of course, the modified skill value rose as well.
• Some Final Fantasy games have an experience-modifying item.
  • Final Fantasy V Advance-exclusive jobs Cannoneer and Oracle have abilities that do this, with the Cannoneer's a more orthodox variant and the Oracle's one more in the vein of JP Up.
  • Final Fantasy VI called it the "Exp.Egg", doubling the user's experience gain.
  • Certain weapons in Final Fantasy VII had Double (or even Triple) the rate of AP gain (which is more important than EXP in the endgame). Not to mention the literal "Exp. Plus Materia" that increased the exp. earned by anyone who equipped it (and could itself be placed in AP+ plus weapon to replicate faster and be distributed to all party members).
  • Certain weapons in Final Fantasy X also had double AP gain.
  • In Final Fantasy XII, the Golden Amulet doubles the LP gained, and the Embroidered Tippet doubles EXP.
  • Final Fantasy XIII had the Growth Egg, which doubles all Crystogen Points rewards for the entire party when equipped on any character. Despite being obviously an Endgame+ item, it is possible to obtain it in chapter 11, halving the grinding required in the rest of the game.
  • Final Fantasy Tactics has the "EXP Up" ability that allows a character to gain more experience for every action. A variation, able to be found on one of the first jobs, increases JP gained instead.
• In Gensou Ningyou Enbu, a Touhou Project fangame based on Pokémon, these appear in multiple flavours. The Combat Handbook item boosts EXP gains by 1.5x when held. The Wooden Sword item boosts PP (Basically the equivalent of Pokémon's Effort Values) gains by 1.5x when held. The Native Grace item increases both EXP and PP gains by 1.5x when held, and the Hakurei Amulet item doubles EXP and PP gains when held.
• Golden Sun: Killing a monster with the right type of Djinn gets increased experience, money, and chance of randomly dropping an item.
• The Inazuma Eleven games, starting with 2, have a passive skill named "gakushuu" (study), which multiplies EXP earned by 1.5x for individual characters who have it. A select few characters come with it already learned, but for the vast majority, it'll cost you 30,000 Nekketsu Points to teach it to them. Like other passive skills, it also takes up one of the 6 hissatsu technique slots each player has — you can overwrite it, but if you want it back later, it'll cost you another 30,000 Nekketsu Points to re-teach the skill.
• The EXP Chance ability in the Kingdom Hearts series doubles your experience (Or more if you stack it) as long as your HP is lower than 25% (50% in Kingdom Hearts II), so you don't even have to endure the accursed beeping if your max HP is high enough. Kingdom Hearts II also includes the Gull Wing keychain, which has EXP Chance as its default ability.
  • The Final Mix version of Kingdom Hearts adds the Tech Up ability, which increases the amount of Tech Points (which translate into experience points) for performing certain actions (such as parrying attacks).
  • Kingdom Hearts: 358/2 Days has the EXP Up ability, as well as an upgrade called EXP Hi-Up, which increases the amount of EXP gained from defeating enemies, with no restrictions on the amount of HP you need to have, unlike EXP Chance. Kingdom Hearts Re:coded brought it back as the Level MAX Overclock ability for the Oathkeeper: Heart keychain.
• In Mario & Luigi: Dream Team, there are both pieces of gear and badge effects that raise the amount of experience gotten for winning a battle. Oh, and one rank up bonus also makes every battle from then on give you 25% more exp as well.
• Mario & Luigi: Bowser's Inside Story: There's EXP-boosting socks that can be equipped.
• Octopath Traveler:
  • The Dancer's Bewildering Grace randomly triggers various effects, including an EXP or JP multiplier. At the end of battle, the multipliers obtained are added together and then multiply your EXP and JP.
  • Certain job support skills from Warmaster and Starseer will boost EXP and JP earned by +50% each for the whole party.
  • Very late in the game, the Captain's Badge and Badge of Friendship accessories are available to multiply EXP and JP earned by an additional +50%, and affects the whole party.
  • On top of those, breaking at least one enemy's armor in a fight gives a +10% EXP "Break" bonus, and winning the fight in the first turn gives a +10% JP "Domination" bonus.
• In Odin Sphere, you can buy a Spirit Gem from the very first merchant you encounter, after the first stage of the game. Equipping this item increases the experience that your Psypher Weapon gains when you absorb phozons. You don't need to have it equipped all of the time, so you can just swap it on whenever you're done killing a wave (or entire level) of enemies. It's also a handy part of the Phozon Farming Abuse trick, which involves using the Phozon Release skill to turn some of your "magic points" into free-floating phozons. Equip the Spirit Gem, release all of the phozons you're carrying, and then reabsorb the phozons. This restores your MP gauge (though not to the same level as before), allowing you release and reabsorb all of your phozons again and again. Doing this often will grind up your Psypher Level, especially with the Gem.
• In Persona 3, there are two types of experience modifiers: Social Links and from after-battle Shuffles. The Shuffles are cards you can earn after a battle that automatically raise how much experience is earned from the battle or randomly raise a persona's stats. Social Links, the higher they are, give bonus experience when creating personae through fusion according to the corresponding Social Link/Arcana. Persona 4 retains the Social Links but ditches the Shuffles (except to gain new personae).
  • The "Growth" ability that some personae can learn (and you can fuse onto others later) acts as an effective experience multiplier, since it lets a persona gain experience and level up even when it's not in use.
• Persona 4: An Arcana Chance effect can do this: 2x EXP.
• In Persona 5 Royal, you can find star-shaped stamps in Mementos. Collect enough and you can trade them in to Jose for a 10% experience boost on all enemies you fight there. You can buy even more boosts, at the cost of higher stamp prices, ending in a permanent boost of double the normal amount of experience you earn.
• By giving them the proper titles, any item from Phantom Brave may become this.
• The Exp. All (from Pokémon Red and Blue/Yellow only) and Exp. Share divides experience gained from battle among your party or a certain Pokémon when held respectively, and Lucky Egg, which doubles the experience gained in battle, and rarely held by Chansey. Traded Pokémon also get an increased experience boost.
  • Pass Powers, introduced in Gen V, include increasing or decreasing experience gained by a little or a lot.
  • The Macho Brace, Power Weight, Power Bracer, Power Belt, Power Lens, Power Band, and Power Anklet affect Effort Value gains after battle, with the first doubling all, and the rest adds 4 to a particular Effort Value for each enemy beaten.
  • The Exp. Share is modified in Gen VI, and now functions like the original games' Exp. All. Did we mention that in Gen VI, Exp. is no longer split between participants, so everyone that gets any Exp. from a battle gains the full amount? In Generation VII and onwards, this was addressed by combining the Generation VI version of the Exp. Share with Generation V's Anti-Grinding, namely your Pokémon gain more EXP by beating higher leveled enemies and less EXP when beating lower leveled enemies.
    • Also, Gen V's Power Passes were brought forward as O-Powers...which you can now use on yourself as well as friends. Lucky Egg + Exp. Point Power Lvl 3 + Exp. Share = 450% Experience. Or, enough to turn the tedious task of high-level grinding into a minor inconvenience.
    • Raising Pokémons' affection to at least two hearts in Pokémon Amie (and its successor in Pokémon Sun and Moon, Pokémon Refresh) grant a 20% bonus.
  • Pokémon GO: The Lucky Egg doubles experience gained for 30 minutes. Occasionally there are events that will grant extra experience.
• In Star Ocean, you can put points earned from gaining levels into a skill that increases EXP.
  • Star Ocean: The Last Hope has a variety of ways to increase XP gain.
  • Certain food items in Star Ocean: Integrity and Faithlessness temporarily boost EXP gain from battles.
• Super Mario RPG has an item straight-up called the Exp. Booster. Whoever equipped it gained double EXP from each fight.
• The Tales Series games feature the Dark Seal, which multiplies EXP earned by 1.5x but increases damage taken and inflicts the Curse status ailment on the party member who has it equipped, and the Demon's Seal, which doubles EXP earned but inflicts various status effects. The latter is very useful in combination with the Yasakani Jewel or Krona Symbol, which blocks all status effects including those caused by the Demon's Seal.
  • In Tales of Xillia, certain food items temporarily increase EXP gained after battle (the best being Spicy Chicken Roll, which doubles it).
• A Very Long Rope to the Top of the Sky: There are the Training Bands, which double experience gain.
• The World Ends with You has several items that do this.
• Xenoblade Chronicles 1:
  • EXP UP Gems increase the character's experience earned from combat. AP Up likewise increases Art Points.
  • Multiple characters have skills that increase their EXP or AP gain; for a couple of examples, Shulk's "Rewarding Work" boosts the EXP rewards from completing sidequests, and Riki's "Riki See, Riki Do" nullifies the 10% penalty to Leaked Experience. With the Skill Link system, these can be used by any character.
• Girlfriend Rescue:
  • Joy learns the 0TP cost "Idle" after levelling up a few times. Its use can reveal that skills gained from reaching new Character Levels can be rewarded mid-battle if enough experience is acquired.
    Restore 5SP and gives 3-5XP to the user
  • Katia learns the 14TP "Learn All The Things" after levelling up about 5 times:
    +LVx8 XPs | - Bored

Fighting

• In Dragon Ball Xenoverse 2, once the player completes the game, they can pick up a special Super Soul item called "40k Weights!" which doubles a player's EXP gains when equipped.
• Ultimate Marvel vs. Capcom 3: Frank can take a swig of alcohol which lets him double up the amount of experience points he gets. This speeds up the leveling process, but after a while he'll hunch over and groan in pain, puking and leaving himself quite open.

First Person Shooter

• Moxxi's Endowment in Borderlands 2 grants a tiny EXP boost in exchange for not using a relic. It is, however, of questionable usefulness, as its boost only applies to EXP gained from kills, not from quests. By that point in the game, usually the only decent exp you can get is from either quests, or joining a friend in a much higher level game and mooching EXP from their kills.

MMORPGs

• Aion also has rest XP as well as bonus XP that starts to show up if you are leveling too slowly.
• In CABAL Online, There are EXP, HP, MP, and item drop boosters that last for a limited time (up to 30 days maximum) available in the Cash Shop.
• City of Heroes: Many of the Day Job bonuses can give bonus XP upon mission completion.
• Dungeons & Dragons Online has the Voice of the Master or Mantle of the Worldshaper that give a 5% bonus, potions for up to a 30% bonus, Tomes of Learning for up to a 20% bonus, and Experience Shrines for up to 5%. All of these stack.
• Final Fantasy XIV: Rested EXP is practically genre-obligatory at this point. There's also "well fed", which provides minor stat boosts (depending on the meal) and +3% experience gain for 30 minutes at a time, and the "armory bonus", which doubles your experience (up to whatever the level Cap was last expansion, at which point the bonus falls to +50%) for leveling any combat class with a level lower than your highest-leveled combat class. Plus myriad miscellaneous other things.
• Granblue Fantasy: The Journey Drop Shop allows the players to buy items which increase the rate at which Experience Points, Rank Up Points, and Upgrade Experience are earned. There are also summons such as the White Rabbit that passively increase the experience points earned in a battle.
• Guild Wars 2 has a variety of exp boost items that can be purchased from their cash store or earned in-game from certain events and chests. The most basic increases character exp for a period of time but there is also a booster that grants increased exp for leveling crafting professions.
• Kingdom of Loathing has equipment and buffs that increase familiar experience. In addition, raising Monster Level (increasing the HP, offense, and defense of monsters, as well as preventing stuns from working and dealing passive damage to the player at higher levels) increases the amount of substats earned from defeating them.
• LEGO Legends of Chima Online: The various types of Intello-Juice grant a fifteen percent increase to the amount of experience points earned, with the duration varying based on what kind it is.
• RuneScape has all sorts of experience boosters. The Runescape Wiki has a list.
• In Spiral Knights, Heat Amplifiers temporarily double the amount of heat you earn for your gear. Activating a new one adds its duration to the current amplifier's.
• Toontown: Corporate Clash: Depending on the day of the week, the game will boost your experience in certain fields, like activities on Tuesday and gag farming on Friday. Alternatively, you can purchase experience boosters with Premium Currency.
• Warframe: Affinity Boosters, which can be purchased or earned from daily bonuses, doubles XP gained in missions for a limited time.
• World of Tanks: Bonus XP is awarded to players with premium accounts, premium vehicles earn bonus crew and vehicle experience (which is normally used to boost crew experience as premium vehicles do not have any modules to unlock for xp) and platoons earn bonus experience if all vehicles in the platoon are the same tier. The first winning battle of the day in a vehicle normally earns double experience and this is sometimes increased to triple or even quintuple for special events. There are also "Personal Reserves" - consumables that when used boost all experience earned by a percentage for a limited time.
• World of Warcraft has Rested EXP. When you log off in an Inn or major friendly city, you build an overlapping meter in which you get double EXP from kills until you hit that point. You wouldn't get boosted EXP from other sources (such as quests), but you wouldn't 'lose' Rested EXP in those cases either (the "rest" bar would adjust itself upward to compensate).
  • Heirloom items (equipment whose stats grow with the level of the character) also have a base increase to experience.
  • Certain World Holidays (the monthly Dark Moon Faire, and the yearly Brewfest, Midsummer Fire Festival, and Hallows End) have ways of gaining a buff for this. The buff does disappear when you die though.
  • The Recruit-a-Friend feature gives triple experience points to both players when they are partied up and with a short distance from each other; although, only one player will receive the extra experience if they are too low of a level compared to the higher leveled player.
    • Unlike Rested EXP, heirlooms, World Holiday buffs, and RAF increase all experience earned. RAF also doesn't use or eat up any earned Rested EXP.
  • Other buffs to experience include: Learning By Example (10% buff to quest experience, random from the Adventurer's Journal), Essence of Wintergrasp (10% buff to experience from mobs in Northrend or Northrend dungeons as long as your faction holds the PvP zone, Wintergrasp), Enlightenment (50% buff to experience from quests and mobs, acquired from completing monk clas quests and dailies).
  • Warlords of Draenor introduced two new boosters in the form of a purchasable potion that increases experience gains by 20% in Draenor and a potion only acquired from a rare garrison mission that quadruples exp gains for 15 minutes. The latter is most commonly used by either drinking it just as you enter a dungeon or just before turning in a dozen or more quests.
    • Mists of Pandaria added a similar elixir which granted increased exp for an hour. It only dropped rarely from two rare mobs.
  • Warlords had several treasure items which on use would instantly reward additional exp.

MOBAs

• League of Legends:
  • Zilean's passive used to be a global aura that gave his team bonus experience gain. It now acts like a Rare Candy.
  • There were a few Masteries and Runes that increased the amount of experience gained. They were replaced with the current Rune system, which don't have any XP-related bonuses.
• Overwatch: Bonus XP is awarded for the player's first win of the day, playing in a group, playing consecutive matches, and joining an in-progress game.

Platformer

• The Scripture in La-Mulana. It's arguable whether or not the experience boost justifies its exorbitant price.
• The "Learn" skill in Level Up, increased by filling out the Codex. Each level increases experience gains by 50%.

Roguelike

• Focus in Cataclysm starts at 100, and increases when your morale is high enough. The more morale you have, the faster you improve your skills. Focus decreases when you are hurt, learn, or have low morale, also making it an Experience Penalty.
• In Dungeons of Dredmor, Big Game Hunters have a chance to earn a bit more experience when killing enemies that are animals, and Archaeologists can get a lump sum of experience by sending enchanted items to the crate room from Indiana Jones. Yeah, it's that sort of game.
• Equin: The Lantern features a "Streak Gauge" that fills as the player scores hits. Once it is full enemies will be worth more EXP, but missing a melee attack, resting at a guild or campfire and the Lantern cycling back to the yellow phase will set it back to zero. The Knowledge status and some rare gear can also give bonus EXP from battles. On the other hand, battles are worth less EXP during the red Lantern phase.

Third-Person Shooter

• Some of the microtransaction items in Battlefield Heroes increase XP.

Turn Based Strategy

• One of the possible unit upgrades in Civilization IV increases the experience gained in future combats.
• The Disgaea series has the Statistician specialist, which can be placed in a piece of equipment to provide as much as four times the normal experience. Couple this with the fact that you can stack as many of them in your equipment as there are spaces available for them, and it becomes possible to hit the level cap of 9999 in a few battles.
  • The first game also handed out statisticians like candy, so this was pretty easy to exploit. Later games typically make them much harder to find.
• Fire Emblem:
  • The recurring Paragon/Elite skill doubles EXP gained while equipped.
  • Fire Emblem Gaiden and Fire Emblem: Thracia 776 have an hidden easy mode that also doubles all EXP gained. In Thracia 776, this perk stacks with the Elite skill for quadruple the benefit; however, the cap is still 100 EXP.
  • Fire Emblem: Awakening: The Veteran skill, exclusive to Robin's Tactician class, increases the user's EXP gained by 50% while they're in Pair Up.
  • Fire Emblem Fates: The Nobility skill from Corrin's Nohr Prince(ss) class gives the user a 20% boost to EXP gained.
  • Fire Emblem Heroes:
    • Upgrading your castle will boost EXP earned up to a maximum of 100%.
    • Experience skills will boost EXP gained for all units using a certain weapon type.
    • Occasionally, there are events that boost EXP gained by 50%.
  • Fire Emblem: Three Houses:
    • The personal abilities of the four main characters — Edelgard's Imperial Lineage, Dimitri's Royal Lineage, Dimitri's Leicester Lineage, and Byleth's Professor's Guidance — all increase their users' EXP gain by 20%. Professor's Guidance also benefits allies adjacent to Byleth.
    • The Experience Gem accessory doubles the EXP the holder earns.
• Heroes of Might and Magic has Learning skill, which does exactly this. Its version from V, Enlightenment, also gives the hero extra stat points every several levels (retroactively), becoming a major Game-Breaker in long games.
• The Super Robot Wars games have the "Gain" and "Cheer" Spirit Commands, which double experience gained from one fight. Cheer can be cast on any friendly unit, but Gain only affects the caster. The most obvious use is finishing off a boss.
• Terra Battle: The Seasoned Pro skill increases EXP gain in battle. The 4.0.0 patch gave the Primordial Dragon Z companion, which doubles your EXP gain.
• Victory Belles: Belles that are classified as training ships (currently Recruit, Jeanne D'Arc, and Amerigo Vespucci) can be deployed on cruises to boost the experience gain of all lower-leveled ships in their fleet. This is especially noticeable for very low-leveled Belles, as a level 1 Belle can gain ten or more levels from a single eight-hour event cruise. Certain traits can also be grafted onto equipment to raise EXP gain.
• XCOM: Enemy Unknown has the Officer Training School (abbreviated OTS). For a one time spending of credits (that you gain monthly, from missions, requests or from selling items on the Gray Market), all soldiers get a permanent 25% increase in their XP gained from killing aliens. Needless to say, this is very Boring, but Practical.

Tower Defense

• A power-up in The Battle Cats called Cat Jobs allows you to gain 1.5x more Xp than normal whenever you beat a stage. There is also a Cat Combo involving the cat unit Professor Cat Jobs that gives you an additional 10% boost to Xp gains.

Western RPGs

• One background in Arcanum ("Nietzsche Poster Child") increases EXP gain by 10% while giving the character a noticeable boost to critical failure rate ("That which does not kill me can only make me stronger."). Unless you are going for a Pacifist Run (as diplomats don't make rolls that can critically fail, but do have limited sources of EXP, even then a permanent boost to your relevant stats, with an increase in cap, in-exchange for blows to combat ones is also a option), it's not worth it, ^note Arcanum combat favors fast weapons with multiple blows over slow strong ones, making failures occur often and combined with Arcanum also using a system of getting EXP per attack instead of per kill means you get enough EXP to reach the default level cap of 50 in normal play anyways anyways.
• In Citizens of Earth, using Nootropics or the School Mascot's "Rouse the Troops" skill in battle will increase the amount of experience earned after the battle. The School Mascot can also increase the monsters' stats, which adds a multiplier to experience earned.
• In Dark Souls, you can get this bonus from equipping the Covetous Silver Serpent Ring, the Symbol of Avarice helm (though that causes a life drain while wearing), and hitting any enemy with half again as much damage as their hit points (even if they already took damage). These three things can stack as well.
  • Dark Souls 2 kept the silver ring, but had three variations each with increasing bonuses (but you couldn't wear more than one silver ring even if they other had different bonuses). And instead of the Symbol of Avarice there are various armor pieces that grant XP bonuses.
• Diablo II:
  • There's experience shrines randomly scattered in some areas, which increase your experience gain from slaying monsters for as long as the shrine's blessing remains active.
  • There were some very high level items that increased XP gain.
• Diablo III:
  • There are experience shrines, whose blessing, along with experience wells, that grant increased exp over a certain amount of exp than time.
  • Player equipment can sometimes have a secondary stat that increases exp; red gems socketed into helmets grant increased exp; and kill streak bonuses give stacking multipliers on total exp for the defeated mobs.
• The Elder Scrolls V: Skyrim has two versions of this:
  • The 13 Standing Stones scattered around the world each give a different mutually-exclusive permanent buff when activated. Early in the game, the Mage, Thief, and Warrior stones are easy to find and provide a 20% increase to all XP gained in their respective type of skills. The Lady Stone (which isn't that far off from the three aforementioned stones) gives you only 15%, but applies it to all your skills.
  • Resting in a bed for any amount of time provides a buff to XP gain for the next 8 hours of in-game time. Any bed will make you "rested" for 5%, but a bed you own (in your home or by renting a room at an inn) will make you "well rested", for a 10% buff. The ultimate, however, is the "Lover's Comfort" buff: 15%, earned only by sleeping in the same bed as your husband or wife.
• Combat in the Fable series was built around the Combat Multiplier system — hitting enemies gradually increased your Combat Multiplier, while taking hits would swiftly drop it. The first game's Mana Shield spell would block hits entirely, which meant that the Combat Multiplier could only drop if you ran out of enemies to beat on.
• Fallout:
  • The Swift Learner perk, which grants a bonus of 5% (1, 2, Tactics) or 10% (3, New Vegas) to experience gained. Since 1, 3, and New Vegas all have Absurdly Low Level Caps, it's not generally worth spending a perk on.
  • Since Fallout 4 removed skill levels and has an Absurdly High Level Cap, Intelligence changes from giving more skill points per level to multiplying your EXP gains. A character with 10 INT will get 30% more EXP than one with 1 INT (fractions of an experience point are carried over, so don't worry about losing anything to rounding).
• Freedroid RPG has "Brain stimulator" addon (helmet only) doing this.
• Your mentor Kreia has this effect when she's in the party in Knights of the Old Republic II: The Sith Lords.
• Mass Effect and Mass Effect 2 feature achievements that grant experience boost.
• The Of Pen and Paper series:
  • Knights of Pen and Paper: One of the room items is a rug that gives you 30% more EXP at the cost of losing control of your characters, this works as well as it sounds since anything more then a single Elite Mook will cause your characters to attack at random enemies, while they will all focus your tank when you're unable to heal besides regen.
  • Knights of Pen and Paper 2: Some of the Sport Games room items have this effect:
    • Bowling Set: Receive 5% more XP.
    • Minigold Course: Battles won within the first round grant you 10% extra XP and gold.
• Titan Quest: Experience boosting effects are always in integers, and work on combat experience, quest experience, and the 85% recovered from touching gravestones generated upon deaths. Not the Intended Use effects of people with 18%+ Experience Booster intentionally dying and reclaiming their gravestone over and over again to make a net profit.
• In Vampire: The Masquerade - Bloodlines, the Saulocept is a unique item that grants a bonus experience point whenever the player character gains 3 or more XP. Unfortunately, it's hidden in a location that's only accessible during one late-game quest.

Non-Video Game Examples

Fan Works

• Trump Card: Judicious use of Uber's Instant Expert power helps Taylor to train various skills permanently, not keeping the power full time, but tapping it periodically to ensure she's practising correctly.

Literature

• All The Skills - A Deckbuilding LitRPG: The "Master of Skills" card lets Arthur pick up new skills at level 3 and then improve them unnaturally fast through practice, to the point where he can sometimes pass off his skills as if they were minor card powers in their own right.
• I've Been Killing Slimes for 300 Years and Maxed Out My Level is set in an RPG Mechanics 'Verse where the protagonist unwittingly levels up and gains a special ability that grants a bonus 2XP per monster she defeats. The difference would be trivial on most monsters, but it doubles the XP reward from the bottom-level slimes she's been killing every day for petty cash over the centuries...
• Saintess Summons Skeletons: The "Blessing of the purifier" offers a 50% bonus to experience gains until reaching level 300, as well as a hundredfold damage increase against demons. Sofia chooses a different blessing for Pareth, though — which turns out to be a good call, because gaining XP is the easiest part of levelling.
• Tree of Aeons:
  • As a reincarnator, Matt receives a soul fragment every time a summoned hero dies, although he doesn't know at first what they do. It eventually turns out that, among other benefits, they're boosting his rate of experience gain by 50% per fragment; when he learns about it, he has 56 fragments, granting 2800% bonus experience. And he keeps collecting more as the years pass...
  • He's later able to project auras around himself to boost experience gain for others in an area (though not on the same scale as himself, more like a 20% boost).
• In Villainess Level 99, Yumiella wears one when she does Level Grinding, instead of a Protective Charm. Everyone else considers that insane. Patrick turns out to have been using one as well in an attempt to get strong enough for Yumiella thinking she'll only marry someone stronger than her.

Tabletop Games

• Dungeons & Dragons:
  • In early editions, having a high value in the correct ability score increased earned Experience Points by 10%.
  • There were magic items that could increase the number of Experience Points gained by the owner or permanently increase a character's level.
