Ok, I've managed to add my reflection code to your modified event handlers, they work perfectly in singleplayer. Now I need to test this in multiplayer.

Ok, multiplayer testing complete, the new modified code works perfectly! Thank you so much everyone! One last question: how do i detect if the arrow was shot by a dispenser? I want mobs like the stray to still be able to deal damage, but arrows from players and dispensers to not deal any. I know how to get whether or not it was shot by a player, but not sure if dispensers are handled differently.

Interesting, I had a hunch that might be the case. Once Im done playing around with it, I'll try that.
