Radiant Strike

You summon radiant wrath from the skies and make a ranged attack roll against a creature within range. On a hit, the target takes 1d6 radiant damage or becomes blinded until the start of your next turn (you choose to deal damage or make them blind). The cantrip deals an additional 1d6 damage to fiends and undead.

This spell's damage increases by 1d6 when you reach certain levels: 5th level (2d6), 11th level (3d6), and 17th level (4d6).
