-- Removes Unlit Poor Torch (6183) from vendors. It's not supposed to be available to players at all. Thanks Ghurok
-- Removes Mood Ring (7338) from dropping. It is only supposed to be available through purchase. Thanks Ghurok
-- The Dragonmaw Shinbones will now drop if you have the quest. Thanks Ghurok
