Now I wish it was the other way round, and one could make some confrontations easier. I don't have super armor. It seems I find only the failed homeworks from magical school. Right now I'm down in the mindflayer nest under moonrise towers. The party is depleted in spells and HP. I can't long rest or fast travel here, can't find a way back out, and I'm supposed to do what will probably be the biggest boss fight from chapter 2 in this state.
I sure hope you have a save from before because this sounds like you're hopelessly stuck.
You absolutely should have had a full rest before entering this dungeon.
I did full rest before entering, but the battle in the barracks and especially the undead was hard. But Meanwhile I found a healing device, like they had on Nautiloid in the intro, and that got my party back in shape for the final confrontation with Ketheric. I downed him, but then things went south rapidly. Every party member and Nightsong were killed by that Myrkul beast in the blink of an eye.
