The Tavern

You can sacrifice weapons to Elyvilon.

I haven't yet tried to sacrifice rods to Elyvilon, even though I know I can use them as improptu weapons (mace/flails!).

Wands cannot be sacrificed, but as they are technically weapons of destruction and wands of draining are penance-worthy, I would think Elyvilon would allow for the sacrifice of any offensive or random effects wand, with special additional piety going to wands of draining and/or higher tier (Fire, Cold, Lightning, Disintegration) wands.

Could save me a trip from throwing it into deep water.

Rocks are in fact sacrificable (is that even a word?).

In fact, large rocks seem to give piety uncommonly often.
