There are a number of ways in which the character can interact with Gods. You cannot contact any god unless you know the right rituals. You can learn a god's rituals by visiting the god's altar, or reading the god's [[BookBooks|holy book]]. Praying to [[Mellis]] will sometimes result in Mellis sharing knowledge of a god that you have not yet encountered. Reading the book of (or praying to) a certain God will raise your relation with that god, and with gods of a similar alignment. The increase is proportionate to the similarity; gods that are significantly different will be displeased, so it is best to pick a handful of similarly aligned gods to pray to.
Using a [[Wand]] of polymorph will change a god's alter into a different god's alter; this does not affect your relationship.
'''Praying''' to a god will have a reward if you are in good relation with that god, and will slightly increase your [[Wis|wisdom]]. Although each god has a different effect, most will also summon new limbs if you are missing a limb, or possibly summon an [[Angel]] to help you. Praying will have a negative effect if you are not in good standing with that god, or if you pray too often. You may only pray to gods that you know the rituals for. If you receive a position reaction, it will be safe to pray again in three hours. In the event of a negative reaction, the cooldown time is generally at least twice as long.
'''Offering''' sacrifices to a god will raise your relationship with that god slightly. There are certain items and materials which Gods prefer, which will raise your relationship more than others (as noted by the god thanking you for your "generous offer")
