Description

A Rainbow Snake is 6 feet long with its body colored on seven segments following a rainbow pattern. Rainbow snakes are most commonly seen after rains. They attack with a poisonous bite, and those bit must make a saving throw against poison or be blinded for 1d4 rounds as they won't stop seeing rainbow-colored flashes. A rainbow snake can also attack by spitting a rainbow-colored spray up to 5 feet. Make a roll for each creature hit to determine the color of the ray that hits them:
