int become_follower	(	object *	op,
		const object *	new_god
	)

This function is called whenever a player has switched to a new god.

It handles basically all the stat changes that happen to the player, including the removal of godgiven items (from the former cult). Handles race restrictions on god, and will punish player if needed.

◆ determine_god()

const char* determine_god ( object * op )

Determines if op worships a god.

Returns the godname if they do or "none" if they have no god. In the case of an NPC, if they have no god, we try and guess who they should worship based on their race. If that fails we give them a random one.

Parameters

op	object to get name of.

Returns: god name, "none" if nothing suitable.
