Stasis beam (Japanese: ), abbreviated stasisbm, is a skill used by Demi in Phantasy Star IV: The End of the Millennium. It inflicts paralysis on a single enemy, if successful. Demi's strength stat, the enemy's strength stat, and the enemy's psi sensitivity affect stasis beam's success rate. Enemies immune to psi effects, particularly machines, saber minions, ghosts, and most bosses, are immune to stasis beam.
Demi already knows stasis beam when she joins the party.
