If the demi-god survives long enough for their deity to win another scenario with the cherry token, there is the chance that they will be raised to full godhood, becoming a deity in their own right. If this happens, the player-god will have it's own religion enabled for other players to follow, complete with spells. The player-god can also move around the board in the same manner as the existing gods.
Current information suggests that as demi-god or god your account will become unplayable. The reward of getting demi-god and become unplayable is a double edged sword as it might be the highest for of reward u also lose your character. The god status was more favorable when there were plans to reset everyone. Now thats no longer the case.
