unkillable Doryani

Hello, today i was on a tier 15 map at doryani and in the first phase he got to the 5% level of life when the culling skill activates and then i tried the culling skill several times, meanwhile doryani kept attacking me until i died. Now i understand the game is in beta but how come no good bugs for the players only bad bugs for us. Anyway, i want my 8% xp i lost and my drop. Fix this for me. Thanks

Earlier a buddy of mine and I took on Doryani in a tier 15 citadel, my buddy croaked right before 2nd phase, I managed to get him all the way down to death but he then stayed hovering and a massive lightning bolt chased me all around the arena for like a minute while i tried to figure out why he wasn't down on the ground dead until my friend suggested i portal out and back in, and when i began the portal animation, the lightning caught up to me and started striking me over and over again until i died right before getting out. lost the xp i had made over the last few hours and everything, PLEASE FIX THIS ENDGAME BOSS BUG STUFF, THX

so frustrating, all this "friction".
