After healing a hero over and over again, or Punishing the incapacitated pawn, a God loses energy. There are quite a few ways of regaining Godpower: by the Sacrifice of an enemy, using the Accumulator, or the most basic method known as prayer. This method regains 15%+ of GP to the Divine Being. It is initiated by telling the hero to do so via a Voice of god message, or the hero can do it of his own accord at a wayside shrine, a temple, or at a bamboo grove with a friend.
Rumor has it that donating 100 gold coins or less restores 20% of GP. Donating more by the Hero increases GP, perhaps even filling the GP to 100%. A good approximation for gain in GP is (gold coins donated - 100) / 10 + 20, which is 80% accurate according to the data collected so far. This formula seems to work best in all towns except Los Demonos and San Satanos (I wonder why godless towns are worse!), so there is probably a coefficient in the actual formula which varies depending on the town the hero is in.
The frequency of donations is still not yet known. Once understood it will be posted in the Probabilities section of GodWiki.
The first step is to roll out a carpet to keep the holy site clean. It must be the preferred color of the God. Next, the worshipper must peform the ritualistic dance his God programmed into him at birth. This dance symbolizes the birth and death, the love and hate, and the undying bond between the Human and their God.
After 10 minutes of continous dancing, the hero must actually say the prayers. The prayer book given to him at birth is taken out and flipped open to a random page. If the page selected is blank (heroes must learn new prayers or create them and write them down in the book), then the hero must make one up.
The final step is the most important. Once finished, the body should be glowing. This glow is the prayer that was said manifesting itself in the real world. The Hero must then focus this prayer into a collimated beam and send it through to his dominant hand. He must concentrate and fling the prayer westward, towards the Trans-Astral Highway, for it to reach the God for who it is meant.
