Arcane Expulsion

A beam of brilliant arcane energy flashes 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 6d10 force damage . On a successful save, it takes half as much damage.

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

For the duration, a mote of brilliant arcane energy glows in your hand. It sheds bright light in a 30-foot radius and dim light for an additional 30 feet.
