Monster skill

From Guild Wars Wiki

A monster skill is a skill that is only equipped and used by 'monsters' (hostile or friendly NPCs, including humans) in the game. They have unique effects that players cannot acquire, ranging from simple effects like Claim Resource to party-wiping destruction like Impossible Odds.

Monster skills cannot be taken by Mesmers via usage of Inspired Enchantment or Arcane Thievery. Similarly, monster skills that are hexes removed via Revealed Hex or Inspired Hex won't be copied. Instead, Revealed Hex/Inspired Hex will instantly recharge. Most monster skills do not correspond to specific attribute lines or professions and thus may be utilized by various NPC professions. Players can only use some specific monster skills while disguised as NPCs, like Junundu, Rollerbeetle Racers, or Turai Ossa, as part of a fixed build that comes with the disguise.

Although many monster skills use a common icon, some have their own icons usually golden in color and few have icons similar to normal skills.
