Haunting Vision

From WoWWiki

Haunting Vision is a level 57-58 undead Scourge officer inhabiting Gahrron's Withering in the Western Plaguelands. They frequently drop runecloth, Invader's Scourgestones, and 1-8 silver and occasionally drop Dried King Bolete, Morning Glory Dew and less frequently Major Healing Potion and Major Mana Potion. Due to their low hit points to overall high loot tables, they are an extremely popular PvE farming encounter.
