Bend Moonlight

Through the mysterious powers of dunamis, you bend space to reflect a silvery beam of moonlight, forming a 60-foot-long, 5-foot-wide Line that arcs out from you in a direction you choose. Each creature in the Line makes a Constitution saving throw, taking 2d10 radiant damage from the searing moonlight on a failed save or half as much damage on a successful one.

Additionally, the fleeting moonlight envelops you, hiding you from sight. After casting this spell, you are invisible until the start of your next turn or until you attack, make a damage roll, or force someone to make a saving throw. 

Using a Higher-Level Spell Slot. The damage increases by 1d10 for each level above 2.
