Saver (セイヴァー, Seivā?, localized as "Savior"), Heroic Spirit of Salvation, is an irregular Servant class that exists within the Moon Cell's Holy Grail War in Fate/Extra. Servants of this class embody the concept of the Messianic figure.
Though Fate / Extra material is inconsistent with other sources in regards to documentation of class skills, its profile entree for Saver gives that two abilities may be common to Servants of the Saver class: Charisma, the natural capacity to lead the masses; and Counter Hero (対英雄, Tai-Eiyuu?), which imposes an effective parameter-down upon any opponents that bear the attribute of 'Hero' (including all 'Antiheroes').
- The only known Servant of the Saver class is Buddha summoned by Twice H. Pieceman.
- Archetype Saber, the original concept for the character of Saber in Fate/stay night, is incorrectly romanized as Saver in Character Material.
