Prayer

Prayer is a combat skill that may grant he or she a buff in combat. All players start with limited access to the Prayer skill. As a player advances their Prayer level, they gain access to new prayers. It allows players to pray for assistance in combat, such as, stat boosts and immunity from attacks. Effects last until the player runs out of prayer points, or a player turns their prayers off. Can also be used to repair or bless Gravestones.

How to train Prayer
You can train prayer in a number of fashions. The most popular being usage on the gilded altar found at home gives 350% increased compared to burying them. Another option is to use the Chaos alter in the wilderness. It can save a bone at a 50% chance. Using this altar is just slightly better then using a gilded altar with its base xp rate. Saving a bone is basically doubling how much xp you get per bone.
