Eschaton is the ultimate attack of Ultima, which inflicts massive Holy-elemental magic damage to all enemies, which is used only when both Ultima and the summoner are both in critical HP. In the International version, this is changed to be used whenever the remaining time left on the summon is less than 10 seconds, making it much easier to use. In the vanilla version, Eschaton has a power of 250, range of 12, CT of 35, and a target of Circle 8, while in the International version, it remains the same but now has a CT of 0 and target of Circle 10.
