Because I've died time after time after time after time after [CENSORED] TIME while standing to the f-ing side of the mob and STILL getting inst-killed on the second use of the death ray.
NO, I wasn't in the wrong spot - I was in the EXACT SAME SPOT as the first time he fired the death ray and I died the second shot EVERY SINGLE FIGHT.
So no, standing to his side doesn't work reliably. But thanks for being such a condescending *****.
