Translucent, slug-like body, made of bubble like-spheres, colored ripples continuously play over its surface. Hovers, rarely touching the ground. Presumed to be from a parallel universe, blinks in and out of physical space, leaving a rotten smell. Appear blurred, as creature is out of sync with the physical dimension. Speaks a language that sounds like radio static.
Special: Distorts dimensions, can flip the quantum states of itself in the blink of an eye, essentially becoming a wave or a solid; after creature makes attack, it has a 1–in–6 chance of blinking away up to 30’ without foe being able to counter-attack; injects sharp needles of hardened light into victims within melee range, causing blood to catch fire, boiling inside their veins for 1d6+2 damage, save vs paralysis for half; attains nutrition from magic, players casting spells on creature must make WIS or INT save, or spell fails, adding 1d4 hp to creature; ten Sun Sprites (other creatures from Night Land) can cluster together in a swarm and attack these creatures as a suicide bomb, effectively vaporizing them both instantaneously from space and time.
