Excuse me, i've been working on this lvl for over 1 week. 

I use Venus, Worlord, Prince Kymar, Coldheart x2 .

Everytime when i almost kill it, it's HP stucked. like unkillabe.  Literaly unkillable.

First i thought maybe it's just lack of luck or lack of damage, but i've tried so many times that it's really UNKILLABE !

Is there anyone have same issue? 

Fix it Plarium ! It's really frustrated....
