supposedly if you've killed the emperor moloch, you instead get the message "The only response to your wish is a slow, menacing, rythmic breath of a being lurking somewhere... out to get and destroy your puny self."
likewise, "*We shall avenge our lord!*" when wished for an already dead minotaur emperor
and quickling bard "Weshallavengeourbelovedchampionofsondandmusicandwillgetyou!" [looks to be a type, sond not sound]
crumpled scroll = blank scroll
marble statue or statue of famous hero = statue
artifacts = nothing

Other potentially worthwhile wishes (rather incomplete): Emperor Moloch - Summons about 35 Greater Molochs randomly in the level (So use the wish in the ID, Ogre Cave, Etc.). If you can handle them in combat this is a massive exp. boost.
