Enchanting is a primary profession that allows players to apply permanent (but replaceable) buffs to weapons and gear, as well as the ability to craft Wands, consumables, and reagents used by other professions. Enchanters also have access to the spell Disenchant, allowing you to destroy items for materials which are used to Enchant items, or sold on the Auction House. Enchanting can be profitable and very useful as it is used heavily for both PvE and PvP scenarios. Engineering is the best combined with Mining.
