Prismatic Spray

Eight multicolored rays of light flash from your hand. Each ray is a different color and has a different power and purpose. Each creature in a 60ft cone must make a Dexterity saving throw. For each target, roll a d8 to determine which color ray affects it.

• Red. The target takes 10d6 fire damage on a failed save, or half as much damage on a successful one.
• Orange. The target takes 10d6 acid damage on a failed save, or half as much damage on a successful one.
• Yellow. The target takes 10d6 lightning damage on a failed save, or half as much damage on a successful one.
• Green. The target takes 10d6 poison damage on a failed save, or half as much damage on a successful one.
• Blue. The target takes 10d6 cold damage on a failed save, or half as much damage on a successful one.
• Indigo. On a failed save, the target is restrained. It must then make a Constitution saving throw at the end of each of its turns. If it successfully saves 3 times, the spell ends. If it fails its save 3 times, it permanently turns to stone and is subjected to the petrified condition. The successes and failures don't need to be consecutive; keep track of both until the target collects 3 of a kind.
• Violet. On a failed save, the target is blinded. It must then make a Wisdom saving throw at the start of your next turn. A successful save ends the blindness. If it fails that save, the creature is transported to another plane of existence of the GM's choosing and is no longer blinded. (Typically, a creature that is on a plane that isn't its home plane is banished home, while other creatures are usually cast into the Astral or Ethereal planes.)
• Special. The target is struck by 2 rays. Roll twice more, rerolling any 8.
