Shaker

Shaker is a magic-attack used by Boomer in Super Mario RPG: Legend of the Seven Stars. The attack is performed by Boomer only. Boomer will strike at Mario or one of Mario's allies and attack thus automatically killing the selected person. This attack can also be countered by wearing a Jinx Belt or a Quartz Charm or by simply pressing A to guard. This attack is similar to Fear Roulette.
