The Tavern

Xom summons enchanted hats that stick on creatures and player. Some good, some bad, and some ugly. Treat the hats as creatures maybe, so they'll disapear

This seems like the kind of thing where if you coded a patch (which is easier than it sounds, you mostly assemble your pet project out of code from other, similar effects), it would stand a high chance of being accepted. Xom's the kind of god where more options / effects is good, so as to provide more randomness, and a certain "balance" is mostly irrelevant.
