In your campaigns, would a cleric building temples to more than one god be acceptable, or would they be expected to be wholly devoted to a single god?
Do you have any mechanics in your games that would let you benefit from spreading your devotion around?
...
How would you handle donations and building of temples to multiple gods?
I kind of always assume that folks in the fantasy world worship a little bit of everything, like in pagan times. A typical peasant working in a farm might pray daily to the deity of agriculture, and on specially occasions might participate in a festival to the sun goddess, or make an offer to other specific gods before going hunting, and so on. Evil deities being much less popular, but there might still be a festival to either please or bane the gods of death to ensure they stay away from the village, or a peasant might secretly make a donation to a deity of diseases if someone in the family gets ill.
OTOH about Clerics I always default to single deities. It's a bit like different professions: there are bakers, blacksmiths and tailors, and while folks need to buy services from all of them, each person works in a single profession.
I wouldn't mind having some Clerics devoted to a whole pantheon however. Maybe a small community can only afford a single Cleric who has to cover a bit of everything, or maybe there are some priests who oversee common temples or keep multiple religions tied together.
I don't use any specific rules for getting benefits from worshipping or donating.
