Once I got into the Goblin sanctum, I followed the quest leader to the priestess since I'm supposed to be hell bent on removing the parasite and supposedly she can help. So off we go to her room, and I split the party and let my pals wait outside. I can't remember exactly how but the sleeping potion didn't end up putting me to sleep, she just aggro'd and I end up having to fight her. Plus she then calls for reinforcements so her mates outside then bang the drums and call for more help so I'm left with a super interesting dual fight. Me + my ranger wolf spider companion vs. Gut, and Lae'zel, Gale and Shadowheart outside fending off the goblins and wargs.
I did manage to kill her solo with my spider help and then had to lock pick the door to get back outside and help finish off.
But then when I explored the rest of the place, every boss immediately aggro'd me so (having read up on this afterwards) I missed out on all the dialog with Minthara and Dror Ragzlin. Is this supposed to be an outcome? Any idea what I did wrong? All the 'walkthroughs' I read afterwards said I should be able to kill Gut in peace albeit 1v1 and then walk away and explore the rest of the place.
