i got a little trick i use, notice the hammer seems to come out from behind you and swing around,
well depending on where an enemy is if they are in melee range can make a big difference between that hammer hitting and not hitting, just keep that in mind,
if they are right up in your face,
it might help to click behind you when you let a hammer go because your character faces wherever the mouse is so the hammer will comeout theback of you which is right in that enemy's face!

times of grace
