You're right of course. I just wanted to finish this quest now that I already was down there. Actually for my lovely wizard the forest was no problem anyway with invisibility, farsight and teleport. Just killed Rehetep... dwarven graveyard, druid dungeon and tomb of the high king next to come. Then I will decide if I'm strong enough for darkforge and maybe even the tower. Actually my only problem at the moment is shortage of offensive spells. I decided to play without stair-hopping and at the moment I only have around 600 magic missile, 150 burning hands and 100 frost bolt. But I won't complain because I got many nice defensive spells and good equipment instead.
