So just finished gearing my dracomorph and took him to the Levels 17 ice golem here I discovered some possibly bugs.

So for his a1 typically smart to get the bosses minon as low on hp as possible and attack him and hope the surplus damage hits the boss. I'm getting 600k+ crits, I'm 2 hitting the boss occasionally !!!!!!!! and the kicker it's not triggering his hp% passive! 

iv done some math and even with the surplus damage tripling I should only maybe doing 200k so maybe the crit damage is being applied again? Dont know its really a bug but should be something to look into.
