Mind Blast (Japanese: ), abbreviated MindBlst, is a skill used by Seth in Phantasy Star IV: The End of the Millennium. It inflicts paralysis on all affected enemies. Seth's mental stat, each enemy's mental stat, and each enemy's psi sensitivity affect mind blast's success rate. Enemies immune to psi effects, particularly Machines, Saber Warriors, Ghosts, and most bosses, are immune to Mind Blast.
Seth already knows Mind Blast when he joins the party.
