Shadow Passenger

4th-level transmutation

Casting Time: 1 action

Range: Touch

Components: S, M (a vial of black ink)

Duration: 8 hours

You step into a shadow you can see within range, melding yourself and all the equipment you carry with the shadow for the duration. Using your movement, you step into the shadow at a point you can touch. Nothing of your presence remains visible or otherwise detectable by nonmagical senses except truesight.

You can perceive the surroundings around the shadow out to a radius of 10 feet, but you have disadvantage on Wisdom (Perception) checks. If the shadow moves, you move with it. You remain aware of the passage of time and can cast spells on yourself while merged with the shadow.

You can use your movement to leave the shadow, exiting into an unoccupied space within 5 feet of the shadow and ending the spell. You otherwise can’t move.

If the shadow is destroyed, such as from a source of bright light, the spell ends, you are expelled, emerging prone in an unoccupied space within 5 feet of where the shadow was located, and take 6d6 radiant damage.

If you willingly exit the shadow, you have advantage on the first attack roll you make before the start of your next turn, and if you hit a creature with that attack, the attack deals an extra 3d8 necrotic damage to the target.
