Guard

In game description- "Completely nullify enemy attack. Watch your MP, though!"

Guard is an initial ability to all characters.

Guard is an odd skill because, it basically blocks an attack and you may hold it until you run out of MP.

A very situational skill maybe if, Character (Mage) was in the party and, a character was attacking

and you guarded it might be a good defensive option or, a sudden attack appears though,

Since you may have up to 3 action skills if you equip this to a character, it takes up a slot.

This may be upgraded at the Mojo-Dojo.

Since this is an action-skill you must press selected button to activate it.
