Holy wrench detail

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

The effect of the Holy wrench is changing the prayer/super restore/sanfew potions formula for restoring prayer from ((level/100)*25)+x to ((level/100)*27)+x, where x=7 or 8 depending on if you are using a super restore or prayer potion. To simplify, this means that the potion will restore 27% of your prayer on top of the usual 7 or 8, instead of 25%[1]. All numbers are rounded down to the closest integer as usual. The result of this change is a different boost to prayer restoration for every single level.

Seen 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.

Some players find the wrench rather useless, as the wrench takes up an inventory space which could instead be used for a Prayer potion. However, with level 50 prayer, having a full inventory of prayer potions (4) will restore 2,128 prayer points (4 * 19 = 76, 76 * 28 = 2,128), while having 27 prayer potions (4) and a holy wrench will restore 2,160 prayer points (4 * 20 = 80, 80 * 27 = 2,160), or 32 more prayer points. Plus, the wrench is technically free, while prayer potions can be very expensive. It can be used effectively if the player doesn't bring an inventory completely full of prayer potions, or when prayer potions are used with food. It is also useful in circumstances where inventory space is not an issue allowing one space to be used for the wrench.

At 99 prayer, the wrench begins to restore more prayer points per inventory than just potions when the player uses 17 inventory spaces or more. i.e. 16 prayer potions and 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.

The wrench does work with Sanfew serum. With 95 prayer, sanfew serum restores 32 prayer per dose, and 34 per dose with the Holy wrench.
