I already spoke to Vlakiith and she commanded me to meet the Guardian and kill him (but I didn't of course). Got the whole creche hostile against me and had to fight my way out of it.

However, I decided to skip the creche purification device quest with the doctor since I heard your character gets permanent debuffs from it.

I'm in Act 2 now and I've progressed up to the point in the Shar's Gauntlet quest where a notification tells you that proceeding with the quest will fast forward events.

I'm torn between going back to get purified in the creche (which I know will never work anyway) or just going ahead with the Shar's Gauntlet quest.

Will Laezel leave my party if she hasn't gotten purified although we have already met Vlakiith and got the creche against us?
