Summon is a skillset from Final Fantasy VII. A player gains access to the skillset after equipping any Summon Materia, however the command within the skillset the player has access to relates to the Materia equipped. Summon abilities can also be called via Cait Sith's Summon Limit Break in Slots. In these cases the Summon is called free of an MP cost, and the ability name will be the Summon's name, with exception to Fat-Chocobo and Gunge Lance.
