Death Flayer
From WoWWiki
Death Flayer is a level 11 rare mob scorpid found roaming the clearing south of the road west of Razormane Grounds in Durotar. He is on a 1.5 to 2.5 hour respawn timer.
Death Flayer is the most vicious scorpid in all of Durotar. He uses his big toxic tail and stings the enemy, who'll collapse almost directly after. He was corrupted by the Demonic Warlocks from the Burning Blade clan when they came to Durotar. This scorpid lives around the rocks near the Southfury River and attacks anyone who gets near.
