The steps will consume 800 prayer points total (200 points per step). The oratory at the east end of the Abbey has an altar where players can recharge points if needed. Attempting a step with less than 200 prayer points will ruin your progress and force you to start over. Completing the illuminated book awards players with 10,000 Crafting experience and 10,000 Prayer experience (first time only). The Illuminated Book of Chaos has better stats than Zamorak's unholy book in all applicable categories.
