A spiked gauntlet is a simple one-handed melee weapon in the unarmed weapon group.[AV:9]

A spiked gauntlet is an off-hand weapon. A character can use a spiked gauntlet to make attacks even while holding another one-handed weapon in the other hand, and can use the other one-handed weapon to make attacks even if it isn't an off-hand weapon. Unlike most magic weapons, enchanted spiked gauntlets occupy the magic item hands slot.

A hand is considered free if wearing a spiked gauntlet, even if used to attack with the gauntlet during the same turn.[MP2:7]

Ardents, artificers, avengers, barbarians, bards, battleminds, clerics, druids, fighters, invokers, paladins, psions, rangers, runepriests, seekers, shamans, sorcerers, swordmages, vampires, wardens, warlocks, and warlords are proficient with all simple melee weapons, including the spiked gauntlet. Assassins are proficient with one-handed simple melee weapons, including the spiked gauntlet.

Other classes do not have proficiency with the spiked gauntlet as a class trait, but any character can become proficient by taking a Weapon Proficiency feat.
