Decimate is a prayer from the Ruinous Powers prayer book, unlocked at level 82 Prayer. It can be used by selecting the Ruinous Powers relic in Trailblazer Reloaded League or by purchasing the Ruinous powers book in Deadman: Annihilation.

Decimate gives a temporary 30% boost to a player's Attack and a 27% boost to Strength. This makes it an offensively superior version of Piety, having a 4% greater boost to Strength, but with the drawback of no boosts to Defence.

The prayer was originally available to use on a beta world as part of the DT2 Rewards Beta after having passed the relevant consultation poll, where players could playtest it in various content before a second poll was brought forward to ask players whether they'd like the prayers to be implemented in the live game as a reward from completing the quest Desert Treasure II - The Fallen Empire.
