Miscellaneous key - OSRS Wiki

Miscellaneous key is a quest item obtained during the Heroes' Quest from Grip. It is used to access the windowed room in ScarFace Pete's mansion in Brimhaven. From here a second player can kill Grip using a Ranged attack, and the first player, the one doing the quest, is then able to retrieve Grips' key from the body. This is one of the keys that cannot be held on a steel key ring.
