Reysalor's Sinister Shade

Your shadow comes to life as a physical force and launches itself towards a target you can see within range. A target must succeed on a Wisdom saving throw or take 1d6 slashing damage and subtract 1d4 from the next saving throw it makes before the end of your next turn.

This spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
