PSA on moonrise

In case it somehow hasn’t been found yet, you can kill the myrkul lady and necromites at the top of the tower before fighting ketheric. Obviously it’s important to do this before entering the main hall triggering the ketheric cutscene. There’s some scaffolding around the side of the tier below that you can jump to (high str or jump spell) and from there cast fly on your party to reach the top. Then kill everything up there.

Also it’s more widely known, but you can do the same with Gortash. Climb the top of wyrms rock and kill the steel watch and bane cultists before meeting him at the coronation, then destroy the little wall device things to make the fight laughably easy.

Edit: it doesn’t make anyone hostile in either instance

You can also do it after the Ketheric scene, you just have to be more careful about letting the Necromites come to you. You can kill the necromancer and the Necromites without aggroing Ketheric as long you don't go beyond the stairs next to the door you enter the roof from
