Psyche!

Psyche! is an attack in Super Mario RPG: Legend of the Seven Stars used exclusively by Clusters. The attack results in a mortal blow for the player, being one of the earliest of these few rare attacks in the game to be encountered. When the attack is initiated, the Cluster targets a character, exploding over them, unleashing a shower of glowing sparks. The victim faints instantly unless they use an Action Command to block the attack or a special accessory such as the Safety Badge.
