Aran doesn't take touch damage when BP kills stuff

Describe the problem. Be as specific as possible!:
If Body Pressure kills a monster outright, you don't take any damage from the hit.

This is a kinda wut thing for me, because Body Pressure does quite high damage to start with. I can't imagine why it would be intentional - it still displays taking damage over your head, HP just doesn't drop.

It's kinda hard to SS the fact that I actually did take damage :/ but I did and that's why the mob has a little HP and I'm not at max anymore.
