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.
Upon learning Enchanting, players will also learn the Disenchant ability. This will allow players to destroy and convert Uncommon, Rare, and Epic quality items into crafting reagents such as Dream Dust, Greater Eternal Essence, and Small Radiant Shard, materials used for enchantments. Items that cannot be equipped cannot be disenchanted, with the exception of bags (as they're technically equipped). In order to Enchant an item, it is required of an Enchanter to have a rod in their inventory. As you level up your skill, you will require different rods, all of which can be crafted from your Enchanting spellbook. Rods are further explained in this guide.
Enchanting is a primary profession, and you can only have two primary professions active at once in Classic WoW.Enchanting pairs well with Tailoring, Leatherworking, or Blacksmithing, as those professions generate gear that can be disenchanted. Tailoring is generally most commonly paired with Enchanting as you can loot cloth needed for Tailored items without having to learn a gathering profession (such as Skinning for Leatherworking). These Tailored items can then be Disenchanted into dust.
For Druids interested in Tanking, Enchanting is essential to craft the Smoking Heart of the Mountain trinket, but it can be dropped after crafting. Cloth-wearers (Mage, Priest, Warlock) need wands while leveling from 1-60, and Enchanting is a source of two easy-to-get wands: Lesser Magic Wand and Greater Magic Wand. As covered in the section above, Tailoring goes well with Enchanting, and cloth-wearers can equip and benefit from crafted Tailoring gear. Enchanters can also create Wizard Oils which casters may consider using as a consumable.
You can enchant your own gear, as well as other players of your faction through the Trade Interface. Open a trade and have their player put their item in the "will not be traded" area at the bottom of the window. Choose the desired enchant in the Profession UI and then click on the item. Enchanters can command tips for providing rare enchants for players, so you may want to advertise in Trade if you have a special recipe.
