Changes

The required number of missions in order to help your deity move is one per wild server and one per home server belonging to your kingdom template. Only missions completed on the Epic servers count – missions on Freedom servers are for fun only and don’t contribute.

When a deity has "enough" collectables and returns to the starting point, that god wins the power struggle and a scenario ends, the winner receives bonuses and may punish the others with some cataclysmic event. (The amount of collectables needed seems to be unknown, so there's no way you can see their progress, as far as I know.) The best way to describe it is a race, however we have no way in knowing how far ahead or behind our deity is.
