Leviathan is another Non-Elemental Summon and despite both of his regular skills require 2 ATB, they’re both useful based on the range of your enemy. Leviathan’s auto-attacks are a lot quicker than Fat Chocobo’s and the Ultimate Attack, Tidal Wave, is a hard hitting one that makes this a better Summon than Fat Chocobo.
