Prayer is a big part of Project Z, it helps you get to places, protects you from bosses and more.
Altars and their locationsEdit
Your prayer can be recharged for no cost at any of the altars in the game. All the altars do work. The one in the Lumbridge church is the most commonly used one, because it's so close to home.
Big bones are one of 4 bone types in the game so far. When you bury them you get 900 experience. When you use them on an altar you get 3600 experience.
