Ars Magica 2 Information
You can charm creatures into fighting for you, and certain creatures will do special things when charmed. Charming also cause creatures to breed (if they are capable of doing so by other means).

Charm is a spell from Ars Magica 2, found under the Occulus's Utility tab and requires a blue Skill Point to be unlocked. It allows the caster to cause mobs, such as a Zombie, to go into battle against other hostile mobs. The target's behavior will become that of a neutral mob in which it will not attack the caster unless provoked. An charmed passive mob will attempt to breed if possible rather than attacking.

Charm will not work against the Ars Magica 2's bosses nor the Ender Dragon, but is effective on the Wither. However, the Wither will continue to target passive mobs and its other heads will continue to launch projectiles toward the player.
