Dark Ray

A torrent of Shadowy Flame Streams 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 8d8 Necrotic damage and is blinded until your next turn. On a successful save, it takes half as much damage and isn't blinded by this spell.

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

For the duration, a mote of roiling flame encases your hand creating dim light in a 5-foot radius.
