Chromatic Neigh

Six 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 60-foot cone must make a Dexterity saving throw. For each target, roll a d6 to determine which color ray affects it. The spell has no effect on shapechangers, creatures with 0 hit points, or horseoids.

1. Orange. If the target fails its save, it is transformed into a Riding Horse as if effected by the Polymorph spell for the duration and its attacks deal an additional 1d4 acid damage as acid oozes from its mouth and hooves.
2. Blue. If the target fails its save, it is transformed into a Sea Horse as if effected by the Polymorph spell for the duration and can breathe both air and water.
3. Red. If the target fails its save, it is transformed into a Warhorse as if effected by the Polymorph spell for the duration. The Warhorse is covered in illusory flames, and it is frightened.
4. Yellow. If the target fails its save, it is transformed into a Draft Horse as if effected by the Polymorph spell for the duration. Its hooves and eyes emit illusory lightning, and it is blinded.
5. Green. If the target fails its save, it is transformed into an inanimate horse skeleton with 1 hit point for the duration.
6. Violet. Roll again on the table. Orange: At the end of its next turn, the target explodes with acid, dealing 8d4 acid damage to itself and all adjacent creatures. Blue: The target is inexplicably immune to all damage for the duration of the spell. Red: The target gains a flying speed of 60'. Yellow: The target's size changes to Huge. Green: The target's size changes to Tiny if it was Large, Large if it was Tiny, or Gargantuan if it was Huge.
