I decided to visit the mountain pass in order to make sure Lae'zel doesn't freak and try to kill me again, But I really want to officially pass via the underdark. So I want to clean up as many lose ends in the mountain pass first, how much of the monastery quest do I need to do for Lae'zel arc to be over (Or be satified)? I already did the weird machine that almost killed her to remove the tadpole and I lied to the captain saying I was just a regular old mercenary.
I'm currently looking for the blood of Lathander. Once I find it I'd like to star heading to the underdark. Have I done ennough to cal Lae'zel? Or will she cause problems in the underdark?
Take Lae'zel to talk to the inquisitor W'wargaz, I believe his name is.
to do that, you have to go through the portal/door in the room with the kith'rak, the captain you mentioned deceiving. to go through the portal/door, you'll need the red gem thing to insert. the captain lady has it in her possession. just mentioning in case you missed it in the cut scene.
