Games in which An Adventurer Is You usually design (or aim to, at any rate) their Class and Level System so that each class only excels in one particular niche and the whole of a party is always greater than the sum of its parts. Some designers realize, however, that there are gamers who play alone for various reasons and tailor certain classes to this preference. These are classes that enable an average player to one-man encounters that others usually cooperate to overcome, but they usually do so less efficiently than a party of specialists. New players will often be encouraged to start with this type of character so that they can find their favorite activities and style of play without having to fish around in the community for teammates. In an offline or single player context, this type of class can familiarize a newbie with the game's mechanics before introducing synergies and group coordination. Solo classes often fall into two broad categories: Classes specializing in solo play:
- The Jack-of-All-Stats, with limited versions or equivalents of enough specialists' abilities that they can keep themselves alive and barely defeat stronger or more numerous enemies without help. Besides striking out on their own, they can be less capable replacements for multiple types of specialists — e.g. becoming a secondary healer or an off-tank.
- The Minion Master, The Turretmaster and any class that can almost create their own party out of thin air to back them up.
- Hunters and hunter-like classes, whose Real Life counterparts are typically portrayed as being masters of the wilderness. With powerful ranged attacks, debilitating traps, abilities that facilitate escaping from tight spots and a strong animal companion, the hunter class are usually a game's designated loners.
- Mighty Glaciers with relatively decent attack power may be able to withstand Mook assaults and whittle down bosses without their usual backup but take an age to complete the encounter.
- Healers with access to instant self healing and token offensive spells may be able to grind down armies or bosses on their own while topping up their health but lack of offensive ability causes the encounter to drag on.
- Nukers with sufficient spell power and space to distance themselves from their target(s) may be able to kite enemies to death before their meager defenses give out. They may also have the option of casting multiple layers of temporary magical defense on themselves and 'bursting' down enemies while protected.
- Gradual Grinders can pop a bunch of Standard Status Effects on a boss or group of enemies and run around until they drop if the game mechanics allow it... usually not for long.
- Dragon Age: Origins lets you do this several ways. First is the rogue. Properly built, a rogue can become essentially immune to melee damage, and resist all but the most powerful spells. Then there's the Arcane Warrior, which you need to unlock during your first playthrough, a heavily armored mage who gets abilities that allow them to seriously reduce or totally nullify all damage and they also have access to heals and powerful offensive spells.
- At one stage in Dragonica the Knight job line was notorious for being a PVP solo class due to the classes' range of defense and damage reflection abilities. DPS classes could literally One-Hit Kill themselves on a Paladin or Dragon Knight if a Critical Hit was scored and said Knight classes also had the best aerial mobility despite being tanks.
- AdventureQuest Worlds has the rogue and the pirate, whose Footwork skill allows them to dodge enemy attacks (and every attack you dodge gets you a little bit of health back), and whose DPS abilities can even allow them to take out bosses solo, especially when Concealed Blade kicks in. The Healer can also solo, but it takes a while and it's limited to how much mana you have and can get back from Energy Flow.
- Many Rank 10 faction classes, such as the Necromancer, the Undead Slayer, the Troll Spellsmith, the Skyguard Grenadier and others are quite capable of soloing bosses. There's also the Paladin, which combines good combat ability with good healing ability.
- In City of Heroes, the Scrapper is the local soloist-class — striking a good balance between absorbing damage and dishing it out, a well-built Scrapper can solo anything short of a full-on Arch-Villain. (And sometimes even that — depending on the version. Early versions had a few exploits that certain builds of scrappers could use to become virtually immortal at higher levels.)
- In City of Villains, the Brute can play pretty much the same role, but the real solo-master there is the pet-centric Mastermind-class, who basically get to bring their own army with them wherever they go. At higher levels, you'll have anywhere from 6 to 8 pets following you around (depending on exact powersets), making it quite possible to handle most bosses on your own — without even getting your hands dirty.
- The Stalker can fit into this role as well by focusing on stealth and hit-and-run tactics using their highly damaging assasination power. While they are a Glass Cannon in the early game compared to the Brute a well-built high level Stalker can have more than enough defense to take on Elite Bosses as well.
- In Team Fortress 2 some of the classes can do their job on their own (for example an Engineer can set up a sentry nest and a Sniper can find a good vantage point, while a Spy can infiltrate on their own). Of course the game is deliberately designed so that having a team mate back them up always helps (e.g. a Pyro to guard an Engineer or Sniper from a Spy, or a group of offensive classes to rush the enemy when the Spy begins sapping their sentries).
- Many classes in Flyff can solo due to Good Bad Bugs or a Gamebreaker. However, the Billposter is usually considered the purpose built solo class due to high damage output combined with decent endurance and the ability to self heal (as an offshoot of the basic healing class). The Battle Priest (A Priest built for fighting instead of healing and using Billposter equipment) is another 'proper' solo class.
- MapleStory infamously has the Clerics and their Prestige Classes being the best solo classes after a certain level as their heals damage undead enemies while affecting themselves as well. Their final job gains the ability to nuke several entire platforms at once, which still puts them ahead of other fourth jobs even after a damage Nerf.
HP priests (priests gearing for HP, which increases durability without sacrificing too much damage) especially could shrug off most enemy hits and heal wounds well enough to keep going. With MP Restore before the Big Bang patch it was possible to wait about a second or so and restore roughly 50 mp during a battle, never using pots or Magic Guard. The patch removed this feature, though (which also had the side effect of making chairs completely ineffective for mage classes).
- Several World of Warcraft classes have gained and lost this designation due to Blizzard Entertainment's constant rebalancing, though Hunters, Paladins and Death Knights have been especially persistent examples in players' eyes. The discovery that any class can solo group content at its original recommended level is usually followed by calls for a Nerf.
- Hunters can solo very efficiently in Eden Eternal due to having most of their DPS come from a powerful tiger companion that can be healed (they are sub-par against bosses that quickly kill or dispel their tiger). The class is exceptionally popular with botters for this reason.
- A Cleric in Neverwinter Nights 2 can handle just about anything the game can throw at it by level 7, or Level 5 with the proper Domains. Once he learns the Divine Power buff, a Cleric can fight better than a Fighter or Barbarian, with as-good-or-better armor, more hit points, efficient healing, and a bevy of available buffs, albeit with a slightly worse weapon selection (which can be remedied by taking better weapon proficiency with a Feat). The only thing a Cleric can't deal with by level 7 is lockpicking, and the game allows the option to smash locked doors and containers. This will cause some items in locked chest to be broken, and deny a stealthy approach, but when you're a combat monster already, stealth is overrated.
- Lockpicking isn't even specifically denied to them. A Cleric is only limited to how high they can raise the skill, but this is irrelevant since, with only a point in the skill, Clerics can open almost every chest in the game with skill and attribute buffs included since you automatically roll a 20 when picking locks out of combat. The only thing a Cleric truly cannot do is detect epic level traps, which requires a Rogue class feat. However, since traps pose no threat to a Cleric, this is not really an issue.
- The original Neverwinter Nights was even worse, with most essential cleric buffs lasting hours instead of minutes per level and spells such as Harm and Heal being more then capable of instantly-killing living and undead enemies respectively. Only after the expansions were introduced did clerics become more balanced, but if a vanilla server has a level cap under thirty, the best build will always be some kind of cleric unless nerfs are involved.
- Guild Wars has the bizarre "55" builds. Using a specific set of items, the character incurs multiple penalties to his maximum HP until it drops to the lowest possible for a maximum level character—55. The character then uses a buff that prevents any single hit from dealing more than 10% of his health bar in damage—meaning all attacks drop to 5 damage or less. This is combined with health regeneration skills, skills that generate energy when struck, and a debuff that causes damage on a foe when attacking. The end result is a nigh-indestructible character that is laughably fragile if enemies just leave it alone for a moment.
- Dragon's Dogma can be soloed with any class by a skilled player. However, the Assassin Prestige Class is notoriously good at lone wolfing. Assassins gain an attack buff when venturing out without their NPC party members (which are actually very effective in this game), which alongside their stat distribution and stealth/mobility skills allows them to One-Hit Kill challenging bosses in certain situations and make many others a No Damage Run. Most feats posted on Youtube are performed using Assassins.
- The Lord of the Rings Online features the Warden, which can handle entire screens full of enemy mobs without any kind of support via drain tanking (feeding off of enemy health to replenish their own). By endgame, they're able to replenish both their magic and health bars without the use of items or buffs from other classes, allowing them to (eventually) burn through any opposition that cannot one-shot them.
- In the Mass Effect 3 Co-Op Multiplayer, if all three of your squadmates bleed out, it pretty much spells the end of the match on Silver difficulty and higher, unless you have some crazy advanced equipment on you—or are playing an Infiltrator. Thanks to their ability to sprint past enemies undetected, Infiltrators can play cat-and-mouse pretty much indefinitely, running from one end of the map to another and whittling down the remaining enemies until the wave is over.
