Gauntlet of Mauling

This +3 mailed glove is adorned with wicked looking curved blades.  When used for a punching attack, your unarmed strikes do 1d6 points of lethal damage (plus the enchantment bonus of the gauntlet), and the hit point damage inflicted is transferred to the wearer (not to exceed normal maximums). 

It also grants a +1 armor class, and does not increase the chance of arcane spell failure if worn by a caster.
