The Pixie Ring is an accessory dropped by Faeries. It offers a decent +10% casting speed bonus at the cost of a bit of intelligence. While it isn't quite as potent as the Hell Bracelet, it is more common and can be used at much lower levels; it also doesn't take away from willpower like the Hell Bracelet does, so it's good for priests, but a level 5 mage is likely to notice the -3 intelligence more than a level 45 would notice the -4 from the bracelet.
