Tempest Griffon Bracers (Patreon)

Wondrous item, rare (requires attunement)

While wearing these oiled bracers lined with magic griffon feathers, your speed increases by 5 feet.

In addition, you can use an action to speak the bracers' command word to vanish into a plume of sparks and feathers. Choose up to 3 different creatures that you can see within 60 feet of you. Make a melee weapon attack against each target, briefly appearing next to each one before making the attack. A target takes an extra 2d8 lightning damage on a hit, or half as much lightning damage on a miss. You can then teleport to an unoccupied space you can see within 5 feet of one of the targets or return to your original space, reappearing in a flourish of electricity, feathers, and wind. Once this property of the bracers has been used, it can't be used again until the next dawn.

And in a gust of wind and ozone, she was gone. As the guard captain picked up one of the stray feathers that had fallen in the woman's place, the groans of his two elite guards gurgled from behind him. As he turned around to see the bodies of the men before him, he felt a crackle of electricity, the familiar scent of ozone, and the sharp bite of a piercing dagger.
