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 [[Book]]. Praying to [[Mellis]] will sometimes result in Mellis sharing knowledge of a god that you have not yet encountered. Reading the book of a certain God will also raise your relation with that god, and to a lesser extent your relation with other gods of a similar alignment. Using a [[Wand]] of polymorph will transform change a god's alter into a random different god's alter; this does not affect your relationship.
