Tiakealic's Constellation Burst

You summon the celesital light from a constellation above. You summon beams of light from 3 stars that burst from the sky towards targets within range. You can target one creature or several. Make a ranged spell attack for each beam. On a hit, the target takes 2d10 radiant damage per beam and must succeed on a Constitution saving throw or be blinded until the start of your next turn.

If you are outdoors at night when you cast this spell, the spell's damage increases by 1d10 for each beam.

When you cast this spell using a spell slot of 5th level or higher, you summon one additional beam for each slot level above 4th.
