Rahmion issues

[Doctor Rogue]

Ok so im on chapter 9 where i have to go into a dungeon to get a fragment of the Twilight edge, The boss in there however, i cannot kill for the life of me, because about 30 seconds into the fight, he sprays goo on Poharan, spawns 4 minions with 3400000 health that take away a quarter of my health a hit, and then he gets enraged 2 seconds later and kills me, Not sure how im suppose to do anything without dying or kill anything without getting 1 shot, but if any of you can enlighten me on what cryptic thing im suppose to do, please do tell me

did you talk to the npc at the entrance before and entered the dungeon via him (or her xD cant remember)? If you just walk into the dungeon the boss isnt scaled down. Try to speak with the npc in front of the dungeon :>

An alternative suggestion would be to ask for a helper in region chat. I know I was asked to help another player in Ebon Hall in this fashion, another may be willing too.
