This next item from Dragon Magazine #99’s Treasure Trove II is Ed Greenwood’s Hand of Remote Action. I nerfed it a bit from the Dragon Magazine write up, since it allowed attacks, choosing instead to copy over the effects of the mage hand cantrip.
Hand of Remote Action
Uncommon wondrous item
This unusual creation is actually two devices: a gauntlet of steel which will change size to fit the hand of any wearer (halfling through human), and a “hand” of solid steel which is identical to the gauntlet in size and appearance. The two items are magically linked, so that the hand can be controlled like a mage hand, with a range of 30 feet.
You can use your action to control the hand. You can use the hand to manipulate an object, open an unlocked door or container, stow or retrieve an item from an open container, or pour the contents out of a vial. You can move the hand up to 30 feet each time you use it.
The hand can’t attack, activate magic items, or carry more than 10 pounds.
The hand is immune to cold, fire, lightning, necrotic, and poison damage, but if it is hit by a magical force of one of these sorts, the spell effect will be transmitted at half-strength to the gauntlet wearer. For instance, if the hand is hit by a fireball of 8d6 strength, the gauntlet wearer will take 4d6 of damage, or 2d6 if a saving throw is made.
It cannot be destroyed by physical attacks, but will become inert if it takes blows amounting to 20 points of damage. It can be “recharged”, negating all damage it may have suffered, by bringing it into contact with the gauntlet before the 20-point limit is reached for a short rest. If it falls inert, either from damage or by moving out of sight of or too far away from the gauntlet wearer, it must be “replenished” by being in contact with the gauntlet for a long rest.
