Ruinous Powers

This item can only be obtained during temporary Deadman Mode events. It may not be currently obtainable. Players cannot obtain this item in the live game.

The Ruinous Powers is a set of ancient Zarosian prayers available in some temporary game modes such as Leagues and Deadman Mode. Originally intended as a reward for completing Desert Treasure II - The Fallen Empire, with some unlocked via boss drops after the quest, they proved difficult to balance and were not added to the main game.

The Ruinous Powers have similar prayers to the standard set of prayers, but are only available at high Prayer levels. Ruinous Powers generally offer damage and accuracy boosts at the cost of higher prayer point drain and no defensive bonuses.

In Deadman: Annihilation, the Ruinous Powers prayer book could be purchased from the skull shop for skull points. Players can swap between the Ruinous Powers and standard prayer book by using the "Swap" right-click option on their deadman's skull, or by using the "Change Prayerbook" option on the Ruinous powers item.

A proposal for a new prayer book, obtained as a Desert Treasure II reward, was first put to a poll by Jagex on 20 December 2022.^[1] Players voted in favour of the original poll by 86.3%.^[2]

On 14 February 2023, a blog post was released detailing the proposed rewards for the Desert Treasure II quest. As part of this blog post, Jagex created a poll which included a question on whether the new prayers should focus mostly on combat, on skilling, or a balance of both.^[3] A majority of players voted that the prayers should focus on a balance of both combat and skilling.^[4]

On 3 March, Jagex released a new blog post detailing their vision for the new prayer book. This initial proposal outlined 22 new prayers, which included utility, combat, protection, overhead, and skilling prayers.^[5]

After player feedback, Jagex adjusted the proposal in an updated blog post, removing the Conservation, Ancient Abundance, Ancient Offering, and Overprotection prayers, and reworking several others.^[6] A poll subsequently followed, giving approval to run a beta where players could try out the proposed new prayers.^[7]

On 12 April, beta worlds became available to test out the Desert Treasure II rewards, which included the Ruinous Powers.^[8] The worlds could be accessed for just one week, after which a blog post was released noting that Jagex were considering changes to the prayers to ensure that they do not impact the long-term health of the game.^[9]

A second beta begun on 14 June, which included several changes to address player feedback.^[10] This beta was intended to run until 21 June, however Jagex announced on 19 June that they would instead be shelving the Ruinous Powers.^[11] In a lengthy post, they explained that their original vision for the content had "fallen to the wayside", that the Ruinous Powers felt like "power creep for the sake of it", and that shelving the content is the best decision for the game. However, they also made it clear that despite Ruinous Powers not being added to the game, the door is still open on new prayers and prayer books to be added in the future.

The prayers have since been made available, having first been made available in the Trailblazer Reloaded League via the Ruinous Powers relic, and again in Deadman: Annihilation, which also came with various changes to the prayers to better balance them for the PvP environment of Deadman Mode.
