Blades of the Forgotten

You summon spirits out of the Shadowfell to coalesce into three blades. You can direct these blades at one target or several within range. Each target must make a dexterity saving throw, taking 1d10 necrotic damage on a failed save. A target that fails its saving throw cannot take reactions until the end of your next turn. On a success, a target takes half damage and suffers no additional effects. If multiple blades are directed at a single target only one Dexterity saving throw is required.
