This skill governs the creation, use, and recharging of enchanted items. Skilled enchanters are more successful at creating new items. Enchanted items burn less power, and are recharged more efficiently from soul gems, for a trained user.
Governing Attribute: Intelligence
UPDATE (August 2010): Enchanters have a 100% chance of success and will happily charge you an arm, a leg, three toes off the other foot and your firstborn to enchant and/or recharge items for you. You, dear reader, aren't quite so skilled and are not assured of success. But you can stack the deck in your favor. First, save the game before trying anything. Soul Gems aren't cheap and it does take a bit of effort to fill them, so let's not waste anything. Second, Fortify your Intelligence by whatever means are available. Even a short-duration spell (3 or 4 seconds) will work since you only need to cast it and open your inventory (at which point time stops).
