Does enchanting a weapon further make the extra damage exponential, or is it a straight line? It seems that enchanting Cloaks of Fire Resist makes them significantly stronger with each +1, has there been any quantification of the extra damage from weapon enchants?
also i got sal thuul for the first time and went into a shop, when i went to pick something up it asked if i wanted to commit this thievery, i chose no. If I chose yes does the shop keeper automatically detect it, or is there a chance for me to get away with it?
