This bug causes item attacks to not have a target after their targeting is affected by Confuse or Charm and their effect is removed before the item is used. To see this easily, the player should have at least three characters in the party and have a character cast Confuse on the item user, while the other should heal him immediately after being afflicted whether it be a physical strike or a spell. The item user should go last. The user will try to use the item but nothing will happen. Magicite Shard and Super Ball seem to be the only exceptions as they don't need a target. Warp Stone won't cast Warp as a result, but will still get the player out of battle if possible.
