In the Fate/ franchise, different Masters provide various power levels for their Servants. Hover over a feat to see which Master is in charge of Gilgamesh.

If a feat references a Class name, assume it is referring to the specific Servant from Fate/Stay Night or Fate/Strange Fake, listed in the table above.

Feats from Fate/Hollow Ataraxia (marked with the HA tag) take place in Bazett's coma.

Feats from the joke series are... well, jokes, and can be ignored if so chosen.

[Bad End] refers to feats that take place in Bad Ends, and while they are not necessarily canon, they are likely capabilities achievable by Gilgamesh.
