To become a follower, you must first have a at least 1.5 [[skillbody]] at 10 or higher. You can then find a follower of that god(dess) and ask them to [[convert]] you.

Note that if you join [[Libila]], you automatically join [[Horde of the Summoned]], and all of [[Jenn-Kellon]] will become enemies of you.
