Umbra's Vow is a prayer from the Ruinous Powers prayer book, unlocked at level 88 Prayer. It can be used by selecting the Ruinous Powers relic in Trailblazer Reloaded League.

Umbra's Vow drains the opponent's Defence by 5% of damage dealt, up to 15% of their base level. This reduction is applied before other defence-reducing attacks such as the Bandos godsword.

Only one Ancient Vow can be activated at a time.

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.
