Mos Le'Harmless is the quaint free port run mostly by pirates that players may visit after completion of the Cabin Fever quest. The isle has a few attractions, such as Trouble Brewing—a minigame—and the Mos Le'Harmless Caves where cave horrors may be found.

Players must either be carrying the Little Book o' Piracy in their backpack or have completed the Rocking Out quest to understand what the inhabitants are saying and interact with them. Otherwise, the pirates and shopkeepers will respond with a fixed script of incomprehensible pirate slang.

Getting there[edit | edit source]

Partial completion of Cabin Fever is required to access Mos Le'Harmless.

Trivia[edit | edit source]

  • The name "Mos Le'Harmless" alludes to The Hitchhiker's Guide to the Galaxy series by Douglas Adams, in which the Hitchhiker's Guide's entry on Earth is simply "Mostly Harmless".
  • Mos Le'Harmless is featured as an Arcanists arena.
  • The patch notes update on 4 August 2010 drastically reduced the rarity of high-level impling spawns on Mos Le'Harmless. Previously, the island was a popular place for impling hunters because of the respawn points that commonly produced implings ranging from nature to kingly.
  • The only accessible part of Mos Le'Harmless used to be the town, which was surrounded in Unknown, but after an update the entire sea around it, the jungle, Harmony Island and the Trouble Brewing minigame became accessible.
