Hedrum the Creeper

Hedrum the Creeper is an elite crystal spider that sometimes appears in Blackrock Depths. When a player enters the Ring of Law in the Depths, an arena event will occur where players have to face three waves of non-elite enemies and finally an elite mini-boss. Hedrum is one of six possible mini-bosses that could appear. The other ones are Anub'shiah, Eviscerator, Grizzle, Gorosh the Dervish, and Ok'thor the Breaker. Don't underestimate her low level - she can bring down groups in seconds.
