The wrench is a quest item used during the Rum Deal quest. It is given to players by Captain Braindeath. Players must then take it to Davey on the ground floor of the rum factory on Braindeath Island to have it blessed, turning it into a holy wrench. It can then be used to defeat the possessed controls on the first floor of the brewery to release a level 80 evil spirit. The spirit can then be killed any way the player wishes.
- Despite its examine saying that it is heavy, its in-game weight is only 5 grams.
