Notes:
1. I encountered this issue on PC
2. I was playing Alone
3. I was playing as Bruenor
4. Believed to be related to Bruenor Battlerager set bug

Steps:
Describe what you were doing before the issue happened.
Trying the Taunt ability since Whirlwind reliable causes me to self-reflect massive amounts of damage while wearing the Battlerager set.

Result:
Thorns triggered a near infinite combo loop when it reflected off a reflected attack, causing massive FPS stuttering. I did hit the biggest combo I'd ever seen, however, at 93,132 hits.

Expected Result:
Reflected damage needs to be really looked at. Right now, I can't use Whirlwind or Taunt with Bruenor's Battlerager set.
