Skill

Servants under the Holy Grail War system are attributed with various Skills that reflect the abilities they had in life, or sometimes those granted by the specific class container in which the Heroic Spirit was placed in.

Skills are divided into two main categories; Class Skills, which are typically connected to the Servant's Class, and Personal Skills, which reflect abilities or anecdotes connected to the life and legend of the Servant themselves (it should be noted that there are certain skills, such as Divinity, which have been treated as both Class and Personal Skills depending on the work and occasionally between different materials for the same work).



Class Skills
Each Class is granted certain Skills upon summoning. They generally reflect the abilities that they had in life, but they will not always have had the corresponding Skills. Even if the Heroic Spirit did not have the abilities in life, they will still get a lower ranked version of the Skill automatically if they fit the class. Conversely, it is possible for a Servant of a different class to gain any of these skills as Personal Skills, as long as they reflect the abilities that they had in life. Class Skills can be lost due to another Skill or Noble Phantasm of the Servant, or due to the Heroic Spirit's nature.

Independent Action
Independent Action (単独行動) is the ability to remain independent even when rejecting the Magical Energy supply from one's Master; the ability that allows for action even in the absence of the Master. At higher ranks, it is also possible to remain for extended periods of time in this world without an established contract. It is both useful and troublesome depending on the disposition of the Servant and the rank of Independent Action. Acting in autonomy from the Master's Magical Energy supply, the Master can concentrate their own Magical Energy on large spells, or the Servant will be fine even in the case they cannot supply Magical Energy due to injury. The downside is that they can be harder to control and keep by their side, making the only true way to command them is by utilizing Command Spells.

Independent Manifestation
Independent Manifestation (単独顕現) is a special Skill that permits unsupported manifestation into reality, without necessity of energy cost or of summoning by a Master; effectively, the Skill serves as an enhanced version of Independent Action. Being that the skillholder is signified as a confirmed existence (存在が確定している), the bearer gains a resistance towards instant-death effect attacks (即死系攻撃) and attacks affected by time manipulation (時間操作). The Skill is normally restricted to the Beast class, and potentially Heroic Spirits that qualify as Grand Servants.
