I can do most of the fight though I'm a bit low on Resurrection scrolls. The worm however can just one-shot my party and if I don't constantly CC Alexander, he will also one shot my party. A lot of my success in the fight has come down to confusing the AI and using those oil barrels. Again, none of this is any good though since once Alexander is down, the worm proceeds to kill multiple party members with one spell.
My main issue with right now with this fight is that I can't find any other way to level up. The entire island's map is uncovered and almost all of my quests are resolved (can't figure out the maze so I teleport cheesed it and it seems a few quests were bugged and just can't resolve). I know I'm missing something but I have to ask how are people even getting to level 8?
