Laughing Skull Berserker

Laughing Skull Berserkers are orcs summoned by the Maniacal Grimace.

Trivia

 * An unused NPC with the same name was to appear as level 94.

Speculation
When considering the presence of the Laughing Skull Orcs in Gorgrond, the Melded Berserker mobs in The Everbloom may be intended to be infested versions of those berserkers.
