Burst Atrocity Demon Lord is arguably even more OP than Phantasm Beastmaster. Also, if the tooltips are to be believed. And it looks like they are. Then damage is currently bugged across the board and items are dealing ~1.937x their intended damage. Which is probably why burst is so damn OP right now. I had 220 Atrocity and 4x damage on the Fluid Prick. So it should have dealt 660-1100 damage. But it's actually dealing 1278-2130 damage.
Edit: This bug also makes it so you can literally oneshot with Lightning Strike before the match starts, just oneshot a 16.8k HP build with it, and depending on the damage roll, could have done 20k+. But since the hit happens before the fight loads visually. I couldn't see what it hit for.
