For future reference, it does damage reflect. It's not at 50% but rather at some other % (Near full hp). Just wait for it to cast it, then it has a 60 second cooldown. You can attack freely for 60 seconds without fear of DR. If you feel you wont' be able to kill it in 60 seconds, attack for like 55~ and wait for it to DR, then attack again once it's gone.
For WH, you can use trap to verify 100% if DR is gone w/o fear.
