Mildred, the final boss in Arcana Heart's story mode, uses light-based attacks (as well as light-based versions of everyone else's Arcana).
In the sequels, she appears as an arcana, adding light-based projectiles to a character's moveset when chosen.
Arknights: Several playable operators and NPCs weaponize light with Originium Arts.
The Nearl family are Pegasus Kuranta with an affinity for light-based Arts, which can be used for both healing (Nearl and Blemishine) and offensive purposes (Nearl the Radiant Knight and Młynar).
On the NPC side, Andoain from "Guide Ahead" wields light-based Arts to protect allies and disorient enemies. As the event boss, he can deploy a light zone known as "Light Onto Sufferers" that gives damage reduction and evasion when the enemies are standing in it.
In Battle for Wesnoth, Mages that advance to White Mages (and potentially later Mages of Light) swap their original fire-based ranged attack for a literal "lightbeam" that does arcane damage instead and is correspondingly effective against, for example, the undead. They also acquire healing powers to go with the theme.
Since the protagonist of Beacon of Hope is a sentient desk lamp, it kinda comes with the territory. At the beginning of the game he doesn't seem able to do much more with his light than glow without being plugged in, but eventually you'll unlock a "frost bulb". (And presumably other element bulbs as well.)
Lao from Bujingai can cast two light-related spells, the Ryuuseiken (Meteor Strike), which is a volley of light arrows, and the Tenseiken (Heavenly Star Strike), which is the up to eleven version combined with Death from Above.
Aurora, the titular Child of Light has Light-elemental magic in the form of Starlight and Light Ray. The former has less cast time and mana cost while the latter is stronger with a chance to instantly kill. Both spells are effective against Dark-aligned foes. Igniculus can also blind enemies with flashes, and any party member can also use citrine oculi to infuse melee attacks with Light damage.
Chrono Trigger - Crono has Heaven-elemental powers in the original Japanese version and Light-elemental in the DS version.note Although they're Lightning-elemental in the English version for SNES.
Chrono Cross had the White element, which included light beams as well as heavenly objects such as comets. Like Crono above, Serge himself is a White-innate.
City of Heroes gives us the Legacy Chain, a law-minded group of mystics who give low-level villains trouble by shooting them with light.
Justicia the elven priestess from The Crystal of Kings, whose powers comes from the honorable Gods of Estorea. Her Smart Bomb attack can cover the entire screen with holy light that utterly obliterates the undead and forces of chaos opposing her.
In Dicey Dungeons, cards associated with light such as Lantern, Northern Lights, and Hall of Mirrors give you extra dice in battle.
Dominions uses the path of astral magic, which is described as raw, unrefined magic derived from the celestial bodies.
In EarthBound (1994), Ness has access to PSI Flash, which emits a bright flash of light that may One-Hit Kill enemies. Lucas can learn it in Mother 3, but it's less effective.
The Holy/Pearl/Fade/whatever line of magic is often the strongest offensive light-element magic of its type. As a late-game spell, it lacks Spell Levels in most games.
Relatedly, Dia and its upgrades, previously called Harm, is represented in remakes of FFI by cathedraling shafts of light from the heavens.
The series' recurring Holy/Light summon is Alexander, an enormous walking fortress whose Signature Move Judgment deals holy damage via either Fantastic Nuke or Beam Spam.
Continuing into Dissidia Final Fantasy and it's sequel with the The Warrior of Light, Prishe, Kuja, and Aerith all specialize in holy and light based magic, while Cecil is a Yin-Yang Bomb
Yuna from Final Fantasy X actually says "Light our way" when she casts Holy for first time.
The EsperUltima from Final Fantasy XII is Alexander's replacement in that game. Her standard ability, Redemption, calls down a beam of holy light to deal damage. When fought as a boss, she uses Holyja at regular intervals and when summoned, her finisher Eschaton uses her cannon as a holy Kill Sat.
Also from Final Fantasy XII, Ashe's Quickenings are all Holy/Light based (with some Shock and Awe too), and the second one - Heaven's Wrath - actually manifests as a giant ball of Holy/Light energy.
Fire Emblem has Light as one of three magic types; it's strong against Dark magic and weak against Anima (and itsthreesub-types by association) magic. While it is the weakest of the three types in regards to raw power (with the exception of the Jugdral games (Genealogy and Thracia 776), where it is stronger than Anima and on the same level as Dark), Light tomes weigh the lightest, which allows for priests and other mages to hit twice from the get-go. Many priests and promoted clerics (both start out only wielding Light magic or healing) also tend to have better skill growths compared to mages and shamans/dark mages, so Light magic garners plenty of critical hits. (Lucius from Blazing Sword is especially good in these regards). In Fire Emblem: The Sacred Stones, Light magic is also super-effective against the monsters that the heroes must fight - even more so when wielded by a Bishop, thanks to the class's skill Slayer.
In Glimmer In Mirror, all fairies - including player character Shirro - uses light as their source of energy when casting spells, though the game exclusively refers to it as "Glimmer" energy.
Golden Sun has a sword known as the Sol Blade that hurls a miniature sun as its special attack (known as an Unleash). Subverted in that the series only has the four Classical Elements, so it's actually Venus-aligned like the main protagonists. This may change, since the third game reveals the existence of Dark Psynergy and ends in light being released unto the world as its own element to counter it. The unleash of another sword, the Phaeton's Blade, consists of striking the enemy with a bunch of rays of light (complete with Lens Flare).
Grandia II has Elena's white apocalypse. It's exactly what one might expect: A light based magical nuke that hits all enemies.
In the Kingdom Hearts series, it's common for the main heroes (Sora, Roxas, Xion, King Mickey, Aqua, and Ven) to have a tendency towards Light based attacks as their signature moves. The three exceptions are Casting a Shadow (Riku, Terra) and Playing with Fire (Axel/Lea) instead.
Queen Minnie is an "escort mission" in the second game. The term is used loosely as she uses light magic so powerful she can clear the immediate area.
In League of Legends, Lux (who actually says this trope) and Leona both use light - Leona uses sunlight specifically, while Lux uses light in general. Both have an emphasis on protecting their allies and hindering enemies, although they do it in different ways. Lucian also uses light offensively, being dubbed "The Lightslinger" and firing it from his guns.
Light is one of the elements from The Legend of Dragoon. The users are Shana and Miranda. Furthermore, only a tiny number of monsters have this element.
Light is a weapon element in Hyrule Warriors, which causes the warrior's power to rise when attacking various enemies at once. It's used in both Link's sword and Horse, Zelda's rapier and Fi's blade. The Light Arrows also make an appearance as a pickup that temporarily enhances the bow and arrow subweapon.
Mega Man (Classic) - Flash Man and Bright Man. Their weapons don't actually control light, though, instead settling on stopping time. Meanwhile, Gemini Man uses Hard Light and Frickin' Laser Beams.
Mega Man X: Optic Sunflower from Mega Man X8, who attacks with lots of laser-based moves, and Shining Firefly/Izzy Glow from Mega Man X5, who attacks with a huge laser. To a lesser extent are Sting Chameleon from Mega Man X and Neon Tiger from Mega Man X3, who use optical lasers and ray sparks/laser claws respectively.
In Octogeddon, the Firefly tentacle can not only reveal cloaked enemies, it will also damage them by shining its light upon them.
In Ōkami Amaterasu can make the sun appear in the sky and change night to day. She is, after all, the sun goddess. She is also weakened during the eclipse at the end of the game.
In Onimusha 3: Demon Siege and Dawn Of Dreams, the Light element appears. In the third, it's linked to the Tenso swords and consist in an extremely fast, multiple slashing attack. In the sequel, Light magic releases a stunning flash of light followed by a Beam Spam attack.
Pokémon, surprisingly, does not have a specific "Light" typing in its wide-ranging Elemental Rock-Paper-Scissors system, though the Psychic and Fairy types seem to be stand-ins for light. Psychic has Pokémon like Jirachi, who takes inspiration from both angels and genies and is themed around shooting stars and wishing, and Espeon, who is opposite the Dark-typed Umbreon and can use sunlight to heal itself in battle. The type also has a few light-based moves (Light Screen and Reflect, for example). Fairy also has a few light-based attacks (Dazzling Gleam, Moonblast, and Moonlight) and is super effective against Dark types. As of Generation VI, the angelic Gardevoir is both Psychic and Fairy type.
Latios and Latias can both reflect light to change their appearance and become invisible. Latios also has the Secret Art Luster Purge, which is either a damaging burst of light (games) or a laser beam (anime).
Solgaleo and Lunala both have control over light. Solgaleo is able to emit light through its Radiant Sun phase, and Lunala absorbs it to glow brightly in its Full Moon phase; both phases are activated when the duo use their Secret Arts. Their relative Necrozma is an all-black prism that not only absorbs and refracts light as deadly lasers, but it can also absorb the two to take on glowing Super Modes.
Necrozma, in general, is the purest form of this trope in the franchise. It can absorb light in such quantities as to plunge places into eternal darkness (such as Ultra Megalopolis) and if given an Ultranecrozium-Z while absorbing Solgaleo or Lunala turns into its true form, a gigantic light dragon. It has two Secret Arts: Prismatic Laser, which prompts it to absorb light and refract it as a shower of dangerous laser blasts, and Photon Geyser, a light bomb attack that's physical or special depending on which attacking stat is higher. It also has an exclusive Z-Move, Light that Burns the Sky, in which it absorbs all the light in the battlefield and concentrates it into a massive energy ball that it then throws at the opponent to essentially nuke it. According to the lore, it used to be a benevolent bringer of light, until the residents of Ultra Megalopolis tried to control it, injuring it in the process.
In addition, there are a few moves of other types that are based around weaponizing light:
The Normal-type Flash is used to blind the opponent and light up dark passages in the field.
Many Electric-type moves have lots of flashing effects. This includes Thunder, which is actually more of a lightning bolt.
Solar Beam, a Grass-type move. It's more efficient with Sunny Day, a Fire-type move.
Flash Cannon, one of the only SpecialSteel-typed attacks in the series. Jirachi's Signature Move Doom Desire is similarly stated to involve concentrated sunlight.
Two Bug-type moves, Signal Beam and Tail Glow, involve bioluminescence, and Bug-type attacks are super effective against Dark types.
Yfus and Santes in The Reconstruction use Divine spells, only a few of which are Holy Hand Grenades. Tehgonan can also manipulate literal light.
One character in each Shadow Hearts game wields the Light-element. In the first game, it's the love interest; in the second game, it's the main character's cousin; and in the third game...it's a Highly VisibleMcNinja.
Additionally, all humans or demons in human bodies are innately immune to light. Interestingly enough expel originally did damage and were usually the strongest spells available to the player, though very few games adopt this method.
In Persona 5, Goro Akechi acts as the team's Kouha and Hama specialist, although his skills also overlap into Holy Hand Grenade as he's the only party member other than the main character to be able to use Almighty skills. He averts this in the third-term events of the game's Updated Re-release, where he prefers to use Curse skills instead, and Kasumi instead becomes the team's resident Kouha skill specialist.
In Persona 5 Strikers, Sophia specializes in Kouha skills to make up for Akechi and Kasumi's absence.
Mythra's Final Smash is Sacred Arrow, which bathes the arena in light.
The main antagonist of the World of Light game mode in the fifth game is Galeem, the Lord of Light. His core is a ball of light, his attacks are focused on lasers and fireballs, and he starts the game by vapourising all the player characters (minus Kirby) in a burst of light.
The main villain of Tales of Symphonia casts light magic and has a strong resistance to your own light spells, as do several of his associates and minions. Collete and Raine's offensive spells are also light-based.
Cheria Barnes and Richard in Tales of Graces. While the game lacks the standard elemental classifications for magic, they utilize spells that are of the light element in the other games, such as Holy Lance and Indignation. Also, Sophie has a definite light theme to her attacks, with the word "photonic" coming up a lot in her arte descriptions.
Tales of Legendia takes a different approach with this trope - Similar to every game, there are indeed light spells like Ray, Brilliant Lance, and Judgment, but there is no actual "light" element in the game - instead, all "light" spells are actually considered "Sea". While kind of weird sounding, it makes sense when the player realizes that the ocean is considered holy in the game world - and that by extension, Water elemental spells such as Spread, Aqua Laser, Malestrom, and Tidal Wave are also this!
Light is the element of the Sixth Fonon in Tales of the Abyss. Its collective sentience is the aforementioned Rem.
Lyla in Visions & Voices. The Wanderer can switch between light and dark skills using a skill called "Reverse Polarity", as well.
The Crack The Sky item in The Binding of Isaac causes a few pillars of light to appear that do significant damage. The item Holy Light causes Isaac's tears to have a chance of spawning these wherever they hit with damage to match.
In his last form, Isaac's boss encounter can use Crack The Sky on a massive scale.
During the second week, Joshua from The World Ends with You reveals that he has the ability to summon holy beams of light from above to strike down his enemies. Needless to say, this greatly increases his battle capabilities.Neku can also gain a Psych called Holy Light that allows him to focus a rapid barrage of light energy on a single foe for continuous damage.
Wisp magic in the World of Mana series is light-elemental. It also includes healing.
World of Warcraft has both paladins and priests, who can use Holy spells to both heal allies and damage opponents. Discipline priests can actually heal people by smiting their enemies. Officially, this isn't always drawn from light - for example, Tauren paladins draw their power from the sun, while night elf priests draw it from the moon. Visually, though, it always looks like light, and several races do draw it from the Holy Light.
In In Famous Second Son, Delsin can gain access to Neon and Video-based powers after defeating and absorbing them from other Conduits. Neon powers lets him fire precise blasts similar a sniper rifle and lets him run up walls while Video lets him fire a constant stream of light blasts and can give him wings for limited flight.
Dragon's Dogma has Light as one of the elements of magic one can use. This can range from Anodyne (a healing spell which heals characters, but only by a grey bar leftover from damage) to Holy Boon (which enchants an ally's weapons with Light, enhancing their ability to fight undead and other enemies weak to Light) and even a flare spell used by Magick Archers to produce a useful source of light. (which has the added bonus to deal decent damage to groups of undead). Light is represented by the colour pink for skill icons.
This is one of the Elemental Powers in Telepath RPG, though it's stressed that it is purely literal light, no metaphysical baggage attached. This doesn't stop Nelis the queen of the shadowlings who are a species associated with darkness from using the romantically-titled "Holy Blast".
In Telepath RPG: Servants of God, Luca can learn Light Blast if you tell her to murder civilians, thus convincing her that she's an angel of destruction. Fittingly, Cygnus' abilities have a light aesthetic as well.
In the campaign of Telepath Tactics, the Mechanics use photokineticists as their psy fighters of choice. (This might be a Call-Back to their use of energy golems in the previous games.) One of your party members, Farasat, is a photokineticist himself.
The Restoration school of magic, which generally focuses on healing spells, has a few offensive spells specifically designed for to harm undead, which includes vampires. These spells mostly take the form of balls and auras of light.
Magnus is the God of Magic and is heavily associated with light. Magnus served as the architect for Mundus, the mortal plane, but realized that in order to create it, the Aedra would have to make great sacrifices and would become forever bound to the world he was designing. Thus, he abandoned the project, and, along with the Magna-Ge, fled to Aetherius (the "Immortal Plane" and realm of magic) which formed the sun and stars in the process. Through them, magic and light flow into Mundus from Aetherius. To the ancient Ayleids, he was actually called "The God of Sight, Light, and Insight".
The Chinese MMORPG Roco Kingdom has Mons called "pets" that, much like the Pokémon, are associated with a specific element and can use attacks involving that element. A few pets exist that can use light to attack other pets and shield themselves from the opponent's moves, with one such pet being Dimo.
In Today I Die, the protagonist uses light to progress through the story.
In The Tenth Line, most of the Princess's or rather, Anne's attacks emit a kind of light energy that is Non-Elemental relative to the game's element system. It turns out not to be a good thing as she has these powers due to a mark connecting her to a world-ending entity of pure light. This also makes her powers the opposite of Tox and the other Black Dracomages, whose purpose is to destroy the light entity once and for all.
their enemies. Officially, this isn't always drawn from light - for example, Tauren paladins draw their power from the sun, while night elf priests draw it from the moon. Visually, though, it always looks like light, and several races do draw it from the Holy Light.
