About training Prayer

Prayer is the classic buyable skill: nearly all of its xp comes from sacrificing bones or ashes, so your bank balance sets the pace more than your play time. Multipliers decide the price - a gilded altar pays 3.5x per bone, the Wilderness chaos altar adds a 50% chance to keep each bone, and Varlamore's libation bowl turns crushed bone shards into cheaper, semi-AFK xp. Free players can only bury bones at face value, which makes Prayer painfully slow in F2P but one of the fastest 99s for members willing to spend.

Did you know: Level 1-99 Prayer is 13,034,431 xp: that's 2,896,541 regular bones buried by hand, or just 51,725 dragon bones at a gilded altar - a stack costing roughly 155M gp at 2026 prices.
