These very rare magical items are of unknown origin and the secrets of their creation remain very well hidden. Each Great Gauntlet is a well-made armored glove of excellent craftsmanship and the finest materials. They are always discovered alone, never in pairs.
A Great Gauntlet will magically resize itself to (properly) fit any human, demi-human, or humanoid of small or medium size. It will also magically reconfigure itself to fit whichever hand (right or left) that it is placed upon.
When worn a Great Gauntlet allows its wearer to wield a weapon that normally requires two hands in one hand with no penalty or negative effect. For example, a human using a shield and bastard sword who was also wearing a Great Gauntlet would cause damage with the sword as if it were used two handed. Likewise a dwarven cleric with a great gauntlet could use a maul one handed without penalty.
Using a large weapon with two hands while wearing a Great Gauntlet has no positive or negative effects.
If a single creature attempts to wear two Great Gauntlets at the same time they interfere with each other; both Gauntlets vanish as they teleport to a random location and the wearer's arms go numb, acting as if they had been withered until the affected creature receives a Restoration.
Great Gauntlets may only be used by fighters, and fighter sub-classes, clerics (but not druids), and assassins.
