[MINOR] Rock Giants

Small comaplint, but needs fixing non the less. The rock giants that roll at you always seems to hit you, no matter how much you avoid them by. If the monster starts to roll, you could be no where near the path of the monster, yet still be hit. Small but annoying.

I have been playing a Witch and get hit every time, but I play with a friend who is a Archer, and he seems to be able to simple dodge each time. almost made a game out of it.
