These somewhat plain looking dark grey arm wraps seem to give off a slight charge that keeps the wearer focused. All unarmed attacks made while attuned to this item grant a +1 attack bonus, and such attacks are considered to be magical.

You can use a bonus action to speak the command word, causing small bolts of white electricity to erupt around your hands. Once per round, when an enemy is hit with an unarmed strike, a thunderous sound and a bright flash of light erupt from the wearer's hands upon contact, dealing an extra 1d4 lightning and 1d4 thunder damage. The sound can be heard in a 100-foot radius, and the flash sheds bright light in a 10-foot sphere. The effect lasts until you use a bonus action to once again speak the command word.

Notes: Damage: Thunder, Bonus: Unarmed Attacks, Damage: Lightning, Requires one hour of mediation, can be accomplished during a short rest.
