Holy wrench

The Holy wrench is a reward for the completion of the Rum Deal quest. It may be worn in the pocket slot.

If players have the wrench in their pocket or inventory when they drink a prayer potion, super prayer potion or super restore potion, they will regain additional Prayer points depending on their Prayer level. The increase is 10-20 Prayer points for each dose of a regular prayer potion, and 10-30 points per dose of a super restore potion. The wrench also affects Prayer points restored by prayer renewal potions over time, increasing them by approximately 5.5%. The effect of the wrench stacks with all tiers of the Reverence aura.

The holy wrench may be used in low-risk combat situations such as Slayer, where signs of item protection or life are not needed.

If a player loses their holy wrench, they can obtain a new one by talking to Davey on Braindeath Island. Having more than one wrench in your possession does not further increase prayer gain.
