Darkbeam

A beam of darkness bursts out from your hand in a 5-foot-wide, 60-foot-long line. Each creature in the line must make a Constitution saving throw. On a failed save, a creature takes 6d8 necrotic damage and is blinded until the end of your next turn. On a successful save, it takes half as much damage and isn't blinded by this spell.

The darkness dispels any light created by a spell of 6th level or lower.

You can create a new line of darkness as your action on any turn until the spell ends.

For the duration, a mote of darkness rests in your hand.
