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.
