Servants are spirits summoned by the Holy Grail to compete under Masters in the Holy Grail War. Typically, they are Heroic Spirits, beings of a higher existence given to them by the people's ideals of them, but can also be Divine Spirits, Phantoms, Wraiths, and even normal humans, in extreme circumstances.

Masters never summon the actual Heroic Spirit itself, and even to the Holy Grail or Counter Force, summoning of an actual Heroic Spirit is impossible. Only the World can directly summon the actual Heroic Spirits, and the occurrence of such is extremely rare.

When summoned by the Grail, instead of summoning the actual spirit, the Greater Grail instead records the information about the Heroic Spirits that is available from the throne, and then creates a copy of that information and forces it into the form of a Servant. In this way the Servants that are summoned are much closer to a shadow of an actual Heroic Spirit, as they are not actually the proper spirit, but a copy of that spirit based off of the information the Greater Grail has gleaned from the Throne of Heroes.


Here are the basic abilities a character can get by being a Servant.


Here are the basic resistances a character can get by being a Servant.

  • Magecraft: Servants, just like Phantasmal Beasts and Dead Apostles, have innate resistance to magecraft due to having Mystery.
  • Poison Manipulation and Acid Manipulation: Servants can resist the powerful poisons of Jack the Ripper and Serenity, and they can move freely in streets filled with gaseous sulfuric acid in London.
  • Soul Manipulation: Just like any other characters in the Nasuverse, a Servant's body and mind protect their souls from harm, and furthermore, they can take hits to their Spirit Origins to an extent.
  • Mind Manipulation and Biological Manipulation: Servants can resist Tiamat's Sea of Life to an extent. All those who enter her Sea of Life are subject to a geas on the cellular level that makes them her minions and enemies of humanity.
  • Life Manipulation and Death Manipulation: Servants aren't alive and aren't considered lifeforms, and because they're just ether in the form of past individuals and not true life, they can survive Surtr's Noble Phantasm, Loptr Laegjarn, which has a "preferential right" against all life, instantly killing whatever it hits, even Gods from the Age of Gods. Furthermore, they can see Osakabehime normally, who induces instant death with her presence.
  • Transmutation and Data Manipulation: Servants can stay in digitized area in SE.RA.PH longer than humans, whereas if a person stays long enough they are turned into data.
  • Absorption: Shown in Stay Night and Extella Link that Servants usually resist the effects of Blood Fort Andromeda, which breaks down everyone in the range into a bloody slurry, releasing their magical energy, and then absorbs it, only suffering a reduction in statistics instead.
  • Heat Manipulation: Servants can take heat from lava and cold from a gas giant that freezes sound with minimal discomfort.
  • Overwhelming Aura and Explosion Manipulation: Servants are capable of living in Age of Gods, when the mana's properties are different, making normal humans explode instantly.
  • Fear Manipulation: Can fight against the Heroic Spirit Swordmasters with no trouble, despite their fear aura
  • Sense Manipulation, Perception Manipulation, Memory Manipulation, Madness Manipulation (Type 2) and Illusion Creation: Servants would have been unaffected by the Bounded Field inside Salem if not for it's divine power. The Bounded Field weakens and messes with the senses, awareness and memories of anyone inside and drives them insane, causing auditory and visual hallucinations
