Psyche!

Psyche! is an attack in Super Mario RPG: Legend of the Seven Stars used exclusively by Clusters. The attack results in an instant death 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 and knocking them out immediately. However, in doing so, said Cluster also destroys itself, taking it out of the battle for good. Accessories such as the Safety Ring make the characters invulnerable to this attack, rendering it ultimately ineffective.
