Mos Le'Harmless is a small island village, which is part of the quest reward for the Cabin Fever quest. There isn't much to do on this island at the moment, except drink in the taverns or buy pirate clothing and swords. Just outside the village you can can visit the cave to kill Cave Horrors to obtain a slayer mask or simply as part of a Slayer task.

Miscellaneous Information
Charter Ships

Certain ships at ports throughout RuneScape now have the ability to charter you to a number of locations. The sailors also stock certain items that they've picked up along their travels throughout RuneScape that you are able to buy. The Mos Le'Harmless charter ship departs to Brimhaven (725gp), Catherby (875gp), Karamja (1,025gp), Port Khazard (1,025gp), Port Sarim (325gp), Shipyard (275gp), Tyras Camp (2,000gp). To halve the cost of these charter ships, wear a ring of charos (a).

For those with level 58 slayer, there is a Mos Le'Harmless Dungeon filled with Cave Horrors. These monsters drop a special mask that when on a slayer task, you can hit harder than you normally would. You cannot double the mask's ability up with a salve amulet. More information about the mask can be found here.


There is a npc on Mos Le'Harmless who if you take a pirate hat or pirate bandana and a eyepatch will attach them into a 'Bandana Eyepatch' for 500gp. If you wish to detach the eyepatch from the hat or bandana, take it back to Patchy and he will detach them for 600gp. He also performs similar services with attaching a highwayman mask to a black cavalier, and a mime mask to a black beret.

There is a special piratical team mini game - Trouble Brewing on Mos Le'Harmless. The purpose is to try and brew rum, but you have to collect the supplies from all over the island and you have the ability to sabotage the other team. This is not a very popular mini game since the island is so far out of the way; so if you wish to play, it's recommended you bring a bunch of friends.

  • The Great Brain Robbery: Start by talking to Brother Tranquility to start this quest.
