Slash-All Materia/Final Fantasy VII

The Slash-All Materia allows the equipped player to carry either the Slash-All or the Flash command. Slash-All hits all enemies at once with a physical attack, while Flash casts the Death status effect on all enemies. Once Flash is learned, Slash-All cannot be used, although the Master Command Materia, when used on a character that has the Mega All Materia equipped, only gives the player Slash-All.
