Alright I'm coming here because I'm starting a new playthrough for the first time in a couple patches and I really don't have much patience for this game, so I'm coming here to ask for as much help as I can get. So I have a few questions in advance that I'd love advice on.

Firstly, is there a way I can rescue Halsin and save the grove without aggroing the entire goblin hideout? Specifically Razglin, it seems like there's no way to kill him that doesn't get the whole camp hostile, but maybe that's been fixed in the latest patch?

Aunt Ethel. What's the best, least tedious way to kill her and save Mayrina?

Once I've gotten through the goblin camp and into that underground section that connects to the underdark, how do I get through the locked gate? I got there before and could not figure out how to get through the gate. That's what made me give up my last run.

I've never seen any underdark content at all so please, give me advice for any and all of it. I don't care about spoilers, I just want to try and have a good time. If I have any other specific questions, I'll ask them specifically. Thanks in advance folks.
