Harlequin Crest is an elite Unique Helm with an item level of 69 and a Character Level requirement of 62.

One of the most popular unique helms in the game, the Harlequin Crest (or "SHAKO!") provides huge bonuses to life and mana, as well as +skills, big magic find, and even damage reduction. These overwhelming bonuses are only partially offset by the fact that it's a lime green dunce cap as distinctive as it is ugly, and sure to clash with any other equipment choices.
