The Ruinous powers is an item purchased from the skull shop in Deadman: Annihilation for 5,000 Skull points.

The item allows players to alternate between the standard prayer book and the Ruinous Powers prayer book. Unlike the version of the item from the Trailblazer Reloaded League, it cannot be equipped.

If lost, it cannot be reclaimed for free; you must spend another 5,000 points to get another. However, it is not necessary to do so, as you can freely switch prayer books via the Deadman's skull once you've purchased the item without needing to keep it.

Some of the effects of the prayers were altered for the PvP environment of Deadman Mode, with the full details of how they functioned listed below.
