~ Caster using his main Noble Phantasm


Caster is a Caster-class Servant able to be summoned by the protagonist in the Grand Orders of Fate/Grand Order.

Caster's True Name is Cú Chulainn (クー・フーリン, Kū Fūrin), the Child of Light (光の御子, Hikari no Miko) and a major hero of the Ulster Cycle in Celtic Mythology. Summoned as a "temporary druid", he illuminates the path his Master walks upon as the true druids did in ancient times.

Stamina: Virtually limitless for as long as he has sufficient mana

Range: Extended melee range with his staff, Several dozen meters with magecraft

Standard Equipment: His staff, various wolf familiars

Intelligence: Caster retains the laid-back demeanor of his Lancer counterpart, but fully showcases his mastery of Primordial Runes that the latter once boasted about in this class vessel. As evidenced by his A-Rank proficiency in Rune Magic, he is able to assail foes with powerful blasts of sweltering heat and flame to keep them on his toes while deftly deflecting oncoming attacks with his staff. His prowess is further emphasized in First Order, where he easily defeats Lancer Medusa with Shielder's assistance by leading her about before catching her off guard with a hidden Ansuz rune and finishing her with another burst of fire projectiles. He then goes on to defeat Archer in single combat, nullifying the latter's strongest Noble Phantasms with pre-prepared runes and evenly dueling him in close combat despite his class's abysmal performance in that area. He also shows a keen eye for strategy as well as a pragmatic mindset in these situations, attacking Archer after blinding him with one of Olga's stones and ambushing Saber Alter while she was in the midst of charging her Noble Phantasm.

Weaknesses: He cannot attack while in spirit form, It is more difficult for him to cast magecraft if he is continuously attacked as he has to draw the runes in the air or a suitable surface

Notable Attacks/Techniques:

  • Wicker Man: Cage of Scorching, Consuming Flames
  • Partial Wicker Man vs Archer
  • Wicker Man vs Saber Alter
  • Continued
  • Remotely triggering an Ansuz Rune
  • Caster's standard fire magecraft
  • Caster's close combat prowess
  • Caster's false Gate of Skye
  • Caster using a Body Double
  • Wicker Man: Cage of Scorching, Consuming Flames: (灼き尽くす炎の檻ウィッカーマン, Wikkāman: Yaki Tsukusu Honō no Ori) Caster summons a sacrifice seeking giant made of wicker countless tree branches to attack his foe. Embodying the legends of the Celtic Druids' rituals of human sacrifice, the giant's hollow nature symbolizes its innate nature to seek offerings for the gods. In addition, he was able to send numerous smaller Wicker Men at Mashu repeatedly in order to teach her how to activate her Noble Phantasm. In First Order, Caster demonstrates the ability to quickly manifest a portion of this giant to attack his foes, restraining and crushing Archer in its grip before slamming him into the floor in a burst of flame. He also displays the ability to use this Noble Phantasm defensively, rapidly growing numerous trees around himself to intercept Archer's arrows and creating a wooden duplicate of himself to avoid Archer's killing strike and retaliate by causing said duplicate to detonate.
  • Ochd Deug Odin: Great God Carved Seal: 大神刻印オホド・デウグ・オーディン, Ohodo Deugu Ōdin: Ōkami Kokuin) Caster's trump card, also known as Matrix Wodan, in which he invokes all eighteen of the original Norse Runes he learned from Scáthach simultaneously while announcing the True Name of this Noble Phantasm. In doing so, he summons the power of the great god of Northern Europe to rain heavy magical damage upon all of Caster's foes. In addition, all surviving enemies will have their status enhancements and bonuses removed while special, continuously active techniques will be temporarily deactivated.

Class Skills

  • Territory Creation (陣地作成, Jinchi Sakusei, alternately localized as "Area Creation"): A skill which quantifies one's ability to create a territory advantageous to them as a Magus. Caster has a B-Rank in this skill that reflects his ability to create a territory that acts as a facsimile of Scáthach's Gate of Skye by drawing runes in the air and the floor, allowing him to completely nullify Archer's Caladbolg II and slam him into the ground.

Personal Skills

  • Disengage (仕切り直し, Shikiri-Naoshi): The ability to break away from combat. Due to having C Rank proficiency in this skill, it also has the bonus ability of returning the conditions of a fight back to what they were at the beginning.
  • Rune Magic (ルーン, Rūn, lit. "Rune"): A skill that measures one's knowledge of this type of this Northern European Magecraft. Unlike his Lancer counterpart, Caster is able to fully display his mastery of the eighteen primeval Norse Runes which he gained from his teacher, Scáthach, as evidenced by his A-Rank in this ability. He primarily uses the rune Ansuz to blast his foes with powerful blasts of flame that he can cast rapidly by drawing them in the air. In addition, he is able to create traps and bounded fields by drawing them on his surroundings in certain combinations for various effects, such as triggering a sizable explosion after stepping on a rune or preventing Caster and his opponent from retreating from or refusing combat with the Ath nGabla spell. He should also be able to accomplish much more powerful versions of the Rune Magecraft used by modern magi, such as cursing others, burning others hearts from the inside out, enhancing his own physical and magical abilities, creating protective forcefields, and erasing his foes' memories.
  • Protection from Arrows (矢避けの加護, Ya-yoke no Kago): A skill that provides an increased defense against ranged attacks by predicting the projectiles' trajectories through exceptional means, such as hearing the sound of air being cut, or sensing the killing intent of the enemy. As long as the shooter is within the line of sight, this skill user can track down ranged weapons with his eyes and defend against them. However, this ability does not apply when these ranged attacks are made from extremely far distances or have a great area-of-effect.
