You direct a blast of shadowy energy at a creature or object within range. Make a ranged spell attack against the target. On a hit, the target takes 2d8 necrotic damage.
- This spell becomes a reaction spell if you have the spells dark II or dark III prepared or set. The trigger for the reaction is when a creature targets you with an attack.
