Something to keep in mind for you casters...
Nukes that push mobs will push them in the direction the caster is facing.
Further explanation,
Facing mob and casting a stun that moves it a few steps will push it AWAY from caster
Facing away from the mob (it's beating on your back) with the same stun will move to mob TOWARDS the caster, or even past the caster depending on how much that spell will move mobs.
This is handy when trying to keep something from falling off the a platform, ledge, ect..
Re: Something to keep in mind for you casters...
yes books. face the direction that you want the mob to move when you stun/knockback.. he will move that way
