Wildfire Cape

Wildfire Cape is a cloak that dropped in Upper Blackrock Spire. Before Cataclysm, it had a large amount of fire resistance but no additional stats. It had been great for characters newly venturing into the Molten Core, though not so useful to players gearing up for Outland by running dungeons.
