Earth (Japanese: ) is a skill used by Chaz in Phantasy Star IV: The End of the Millennium. It inflicts paralysis on a single enemy, if successful. Chaz's mental stat, the enemy's agility stat, and the enemy's psi sensitivity affect earth's success rate. Enemies immune to psi effects, particularly machines, Saber Warriors, Ghosts, and most bosses, are immune to earth.
Chaz already knows Earth when the game begins, and must be equipped with a sword or dagger in order to use this skill.
