Hypnosis Spell

We think Minecraft Dungeons could have a hypnosis spell.   This spell would take control of a hostile mob to be on the players team for ten seconds. Not all hostile mobs being battled at the moment just one certain mob, for example just zombies when battling in a scene that includes zombies, skeletons and spiders. As the spell became more enchanted more powerful mobs would be selected.  If the spell was used during a time when only one hostile mob is present the spell is a "dud". 

The order of enchantments upgrades we think should go from spiders/sheep, next to zombies or mallee creatures, next to archery or projectile mobs, then finish with magic mobs for instance ender men. We think the spell would look great as a telescope with a hypnosis swirl on the front.
