[Balance] Shopkeepers should see in the dark
Yeah, screw you gut!
Stealing from shops is made much easier for anyone with a darkness scroll or the spell, since one can avoid the shopkeepers wrath and any alignment hit by bolting him from darkness and teleporting away. Some lowly individuals even abuse darkness to kill shopkeepers without risk. Stealing from the casino is particularly easy with this trick.
I suggest making shopkeepers able to see in the dark to remove these abuses.
