Dawn Bolt

You extend your hand and fire a blast of radiant energy from your palm. Make a ranged spell attack against the target. On a hit, the target takes 1d10 radiant damage. If you are under direct sunlight, the target takes fire damage equal to your spellcasting modifier. 

This spell's damage increases by 1d10 when you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10).
