Skill

Skills are the embodiment of a Servant's various abilities and characteristics. They 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.

Certain Skills, such as Divinity, 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, particularly within the Holy Grail War system. They generally reflect abilities that the Heroic Spirit had in life, but they will not always have had the corresponding Skills. Even if the Servant 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. The Skill Distortion, for example, forces a Class Change upon a Servant, granting them a Class Skill from the new Class in exchange for downgrading a Class Skill of the old one.

Personal Skills

Personal Skills reflect the abilities a Heroic Spirit had in life and their personal legends. As they are not strictly symbols of Heroic Spirits to the same extent as Noble Phantasms, there are many cases of Heroic Spirits having the same Skill, such as the highly universal Battle Continuation.

id_es

In Fate/Extra CCC, id_es (イデス, Idesu^?) are typically special, inborn Skills possessed by BB's Alter Egos from the moment of their creation. They are "cheat skills" resulting from illegal modification through morphing and reinforcing their existing abilities, making most of them Skills that normal Servants do not possess. They are the exposure of an individual's psyche rather than the abilities of the body.

Mecha Eli-chan and Mecha Eli-chan MkII are the first Servants outside of the Sakura Five to be shown with id_es.

In Fate/Grand Order

The game system of Fate/Grand Order (and subsequently Fate/Grand Order Arcade) classifies skills that are always active as Class Skills and skills that can be activated at any time by the player as Personal Skills. The result is that some inherently Personal Skills are treated as Class Skills, and vice-versa. The English localization labels them "Active" and "Passive" Skills.

Some Noble Phantasms are also treated as Skills, which is occasionally explained as them lacking the power of a True Name release.

Originally, Fate/Grand Order had Servants largely share from a pool of generic Skills, especially in regards to Class Skills, as had been the case with previous Fate works. The few truly unique Skills (固有スキル, Koyū Sukiru^?) were indicated as such in character profiles. Later versions of the game began to introduce much more idiosyncratic Skills for each Servant, either upon release or through Strengthening Quests that convert one Skill into another.
