Theogenesis

You place a divine spark into a mortal creature,
unlocking the potential to ascend to godhood.
Choose a target, you must remain in contact
while casting the spell. If contact is broken, both
you and the target take 20d6 radiant damage. If
the spell is successfully cast, then one of the gods
appears and decides whether or not to grant the
divine spark. The creature's relationship with
the god determines its chance of success .
