I was thinking it'd be pretty funny to have the following wishes available "Destroy all Clams", "Destroy all Bloodstones", "Destroy all Fetishes".

Definitely put a cap in how much clamhoarding goes on right at the point of the game that clamhoarding gets critically silly.

No reason to stop there though, the potential of destroying all rings of water breathing, dousing rods, staff of storms, and marble armor would encourage a good diversification of items. Probably too devastating to destroy all amulet of the fishes though as there isn't really an alternative...
