Galvanic Steelsnare

This magic net is made with fine steel chains and has the heavy property. Magic, leaden weights line the edge of the net and send shocking pulses throughout the metal. The net is resistant to slashing damage and has immunity to all other damage types. Regardless of a creature’s abilities or magic items, it can’t make more than one melee or ranged attack during its turn while it’s restrained by the net.

While a creature within 30 feet of you is restrained by the net, you can speak the net’s command word as a bonus action to cause it to release a painful wave of electricity, dealing 1d6 lightning damage to the restrained creature. If the net is restraining a creature made of metal or wearing metal armor, it deals 2d6 lightning damage instead. Once this property of the net has been used, it can’t be used again until the start of your next turn.

A creature can use its action to make a DC 15 Strength check, freeing itself or another creature within its reach on a success. A Small or smaller creature has disadvantage on the check. Dealing 15 slashing damage to the net (AC 12) also frees the creature without harming it, ending the effect and destroying the net. Once destroyed, the net magically repairs itself over the course of 1d6 + 1 days.
