Tetradopterus Wingblade

This sleek, curved blade is crafted from the talons and feathers of the Tetradopterus monstrosity, giving it an otherworldly sheen. When wielded, the user gains a +1 bonus to attack and damage rolls. Additionally, the blade has the ability to create bursts of wind. Once per short rest, the wielder can use a bonus action to unleash a gust of wind in a 15-foot cone originating from themselves. Creatures in that area must succeed on a Strength saving throw (DC 13) or be pushed back 10 feet and knocked prone. Creatures who succeed take half damage and are not pushed back.
