Mighty Guard (ability)

Mighty Guard is a blue magic spell that gives positive statuses to the party against attacks and magic.

Final Fantasy V
Casts Protect, Shell and Float on the party. The only enemies that cast it are the Stingray, Azulmagia and Shinryu. However, to make them cast it on the party, you must either control them, in the case of the Stingray, or cast Reflect on them. In the Advance version, the Ironclad enemy also casts this spell.

Final Fantasy VI
Usable by Strago. Safe and Shell on all party members. Named "Big Guard" in the English translation. 80 MP.

Final Fantasy VII
An Enemy Skill, which can be acquired relatively early in the game. Use Manipulate on the 'Beach Plug' monsters on the beach near Costa del Sol to obtain it. Casts Haste, Barrier (Protect) and MBarrier (Shell) on the party. A useful alternative to the spell 'Wall', as it can be obtained earlier.
