Swordbeam

A beam of brilliant light flashes out from your sword in a 5-foot-wide, 30-foot-long line. Each creature in the line must make a Constitution saving throw. On a failed save, a creature takes 1d6 + 1 radiant damage and is blinded until your next turn. On a successful save, it takes half as much damage (rounded up) and isn't blinded by this spell. Creatures with an evil alignment have disadvantage on this saving throw.

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

For the duration, a blade-shaped projectile of brilliant radiance breaks from your sword. It sheds bright light in a 10-foot radius and dim light for an additional 10 feet. This light is sunlight.
