I notice a few comments about level 5? I am trapped at lvl 4.. is there something im missing
I think they mean that when the level cap is gone you would likely be level 5 when you reach the gith.
On the fight itself, it was less challenging than the swamp fight for me. Probably because I figured I should split the party and leave mage and cleric on the bridge. Then triggered a conversation with Astarion and he was able to misty step to height advantage leaving just lae'zel down below. And she can take some beating.
