I rolled a gray elven wizard with a really decent 13 To potential. The problem is, some hours later I'm level 23, ready to go to Tower of Eternal Flames and I'm stuck at that 13/13 To. I still have the Ice Queen's second quest to do and I have 2 potions of gain attributes but that will take me only to 17. Not cool. No potions of toughness in sight. I still haven't been to casino (obviously) and haven't tried to loot the underwater cave, but I don't have very high hopes anyway. Pools in Darkforge aren't even touched, but I'd rather not gamble there, I have some nice intrinsics I don't want to lose and Khelavaster is saved already.
Is there any other way to train Toughness? Is eating undead corpses reliable enough? (I don't want to lose too much alignment.) I tried training with Garth earlier, but 10k gold did nothing. If I give him, say, 50k, will it help? Or should I try Minotaur Maze? I've never been there before actually. :)
