The Barber

The Barber is a Legendary Ceremonial Knife (dagger prior to patch 2.5.0) in Diablo III. It requires character level 14 to drop.

This dagger used to increase Critical Hit Damage prior to 2.5.0, which is normally not allowed on a weapon. Prior to patch 2.4.3, it also rolled five Primary affixes.

As of 2.4.3, it gained a unique affix: Spirit Barrage no longer deals damage on impact, but instead accumulates it until the casting is stopped for any reason. Once it happens, all affected enemies each explode for up to 500% of full accumulated damage to all nearby foes (and themselves), with possible interlapping.

For the Phantasm rune, the "stop casting" moment is the time when they expire, detonating all enemies they attacked over the duration.

The Manitou rune will trigger the explosion when enough damage has accumulated to kill the target.

Trivia

 * This is one of the few legendary weapons that do not use an original model, instead using the same one as Simple Dagger.
 * Prior to release, it had a different graphic (resembling the Kill dagger).
