Prayer power has a cap which is directly related to the village's (or villages of the same tribe) population (becoming higher as the population grows), although it is possible to go over that cap with sacrifices. The amount of prayer power can always be seen at the worship site's altar by hovering the hand over it. A flame-like plume of energy of the player's color at the altar also offers a visual effect, getting higher as prayer power grows. In Black & White 2, prayer power is replaced by mana.
