Prayer

You train the skill  Prayer  to gain trust from the Gods. With the more experience you gain, you can use higher prayers for better bonuses from the Gods and you will manage to keep your prayers active for a longer period of time. To train Prayer you bury the death, or actually, just their bones. Many Monsters leave bones behind that you can bury to gain Prayer experience. You can also use the bones on a altar to gain double experience. There are two types of prayers you can choose from; Normal prayers and Curses.

Almost all monsters except for most demons drop bones. Some drop bigger bones, granting more experience. Examples are Hill giants, Dragons and Dagannoths.
