Choco Mog Materia/Final Fantasy VII

The Choco/Mog Materia allows the equipped player to perform the Deathblow‼ summon during battle, which deals Wind damage to all enemies, and may also cause Stop. There is a 15/256 (5.86%) chance that a Fat Chocobo will appear rather than Choco/Mog, in which case damage is increased by 25%, but there is no chance of Stop being caused.
