High Quality Content by WIKIPEDIA articles! Assassin (Also known as Rogue, Thief, or Ninja) is a character class common to many games. Such characters typically combine elements of combat gaming with strong stealth skills, and specialise in defeating an enemy without becoming involved in a protracted melee. They are seen as the "fragile, but deadly" ninja-esque character class and are usually recommended to more experienced players in the game. Assassins have appeared in games like Diablo 2, Ragnarok Online, Lineage II, World of Warcraft, MapleStory, and Guild Wars.
