The flame Tang totem within TBC does this where it basically grants your main WoTLK Classic Gold hand weapon an imbue that is similar to as a flame Tang weapon does for you with the Charmin. If you are given the amount of damage it can deal on a weapon swing well it's not anymore.
It's now just flat spellpower. It's certainly not as powerful as that demo Warlock and the Elemental Shaman's...
