Nature Of Divinity

Ways to Ascend to Godhood

Performing a legendary deed
Being given a portion of an existing gods divine power, e.g. The god of war decides to give you some of his power to make you a demigod of duels.
Stealing a gods divine power
Killing a god
Being worshipped, legitimately without mind control, as a god; humanoid or magic sacrifice speeds this along, so wars have been fought with this singular goal.
