Tower Defense - New tower idea: Pacifier Tower

[guardtown]

The Pacifier is my idea for a tower that, every once in a (long) while, it makes mobs turn against the other mobs. It has 4 levels, is 5x5, targets ground only. Non-pacified mobs deal the same amount of damage to pacified mobs.
LEVEL I

900 Coins
"Makes mobs turn against each other."
Pacifier mob health regen: Gains 50% of max health. Cannot exceed max. (when it pacifies the mob, it gains 50% of it's normal health back but it can't go over the maximum health for the mob and it's level. (let's say it pacifies a zombie which has 30 health and the max health for a zombie is 50. It will get 50 health because 55 > 50.))
Pacifier mob damage: 15 (Damage on contact with non-pacified mob. Like a sorcerer minion)
