Iron Sphere (アイアンスフィア "Aian Sufia"?) is a Tech in Chrono Trigger. It is a common magical physical attack used by enemies that are seen in the latter half of the game, notably by Golem. It drops a massive iron sphere on only one target, halving they're HP. When the target has 1 HP, it will do 0 damage, thus this attack by itself will never kill a target.
