The holy wrench is a reward for completing the Rum Deal quest. If players have it in their inventory when they drink a prayer potion, prayer mix, super restore potion, or Sanfew serum, they will regain additional Prayer points, depending on their Prayer level.

The effect of the holy wrench is restoring an additional 2% of the player's Prayer points when the player drinks a dose of any prayer restore potion. This means that each dose of the potion will restore 27% of your prayer on top of the base restore of 7, 8, or 9, instead of 25%. All numbers are rounded down to the closest integer.

If lost, it can be recovered by talking to Davey in the brewery on Braindeath Island.

The prayer cape also provides the same effects as the holy wrench.

The holy wrench can be used to imbue the ring of the gods into the ring of the gods (i) along with 650,000 reward points in Nightmare Zone. This does not consume the wrench. The ring of the gods (i) shares the holy wrench's effect. The effects do not stack.

Listed below is the gain per dose of potion when using a holy wrench at different levels.

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

Uses

As the holy wrench's direct effect is minimal, it is often more beneficial to use the inventory slot for another prayer potion. However, the wrench can instead be used to save prayer potions for cost effectiveness in situations where extra inventory slots are not needed.

However, depending on the player's Prayer level and whether they are using prayer potions, super restores or Sanfew serums, the holy wrench may save more prayer points than another potion would. For maximum prayer restoration capacity, the formula: ${\frac {p}{n}}+1=s$ can be used, where p is the amount restored per dose (without the wrench), n is the extra prayer points from the wrench, and s is the amount of potions needed where replacing one with a wrench does not matter for capacity; if there are more slots available for prayer potions than s, a wrench may be used for higher capacity.

At 99 Prayer, the holy wrench begins to restore more prayer points per inventory than just potions when the player uses 17 inventory spaces or more: 16 prayer potions with a wrench restores more prayer points than 17 prayer potions, whereas 15 prayer potions and a wrench restores fewer prayer points than 16 prayer potions. With the +2 bonus, bringing 12 prayer potions and the holy wrench provides as much prayer restoration as bringing 13 prayer potions, and with the +1 bonus, bringing 24 prayer potions and the holy wrench provides as much as 25 prayer potions.
