Alpha's Sparkle Beam

The caster calls upon the Positive Plane and summons forth a cone of shining silver and gold lights. These shoot off towards one creature within sight, who must make a Constitution saving throw or be blinded until the beginning of its next turn.

An Undead or Fiendish creature who fails its save will also take 1d8 radiant damage.

Leveling: This spell does an additional 1d8 radiant damage when the caster reaches 5th level (2d8), 11th level (3d8) and 17th level (4d8).
