Duskwalker

You fade into nearby shadow, disappearing into the darkness and reappearing in the corner of one's eye, in light just dim enough to obscure your emergence.

Step into a shadow and choose a location obscured by dim light or darkness up to 15ft of you and teleport there. If you choose to teleport close enough to an opponent and make an attack, deal an additional 1d6 Psychic damage upon a succeeded hit and failed Wisdom saving throw by the target. If the target is hit but succeeds the saving throw, they do not take the additional Psychic damage.

At Higher Levels. When you cast this spell at higher levels, increase the Psychic damage dealt by 1d6 with each additional level.
