Yeah I just killed them, Underdark is the last thing ive done after finishing the entire above ground map so I hit the level cap ages ago, I assume you are just meant to tackle them quite late in the game, if you do the goblin camp and then choose the temple underneath as the way of progressing. Lae'azel for me is a beast at the moment, she has a warhammer that does knock back and has her skill that does knock back so she just whacked them around the underdark and my other characters basically just supported, although saying that, Shadowheart has necrotic touch and the level 2 version of that is regularly hitting for high 30s damage so she is no slouch either. Bane helps a lot because it affects their saving throws and then they do their own skill which always give you advantage of attack so my characters were always hitting and then critting quite often.
I think it was largely down to being over-leveled but I think thats just how you are meant to do them.
