  • Plant Speech. extraplanar plants
  • Verdant Burst. When the Color Out of Space Swarm dies, a burst of primal energy explodes from their body, restoring 31 (7d8) hit points to each plant creature in a 30-foot radius. All plants within the area grow to a massive size, making the area difficult terrain. Plants in the affected area return to normal after 24 hours.
  • Incomprehensible. With a color that cannot be grasped by mortal minds, glimpsing the Color Out of Space Swarm causes physical pain. Those starting their turn within a 30-foot radius of the swarm or enter the area for the first time on their turn must make a DC 15 Wisdom saving throw or suffer 18 (4d8) psychic damage, taking half as much on a success. Creatures who fail the save by 5 or more are stunned until the end of their next turn.
  • Plant Swarm. The Color Out of Space Swarm can move through a Medium or smaller creature’s space, suffering no penalties.
  • Mask Color. The Color Out of Space leshy shifts its color, appears as an ordinary, grey field of plants plant it is based on. While in this form, the leshy is indistinguishable from a normal (albeit discolored) field of plants so long as it remains motionless.


  • Color Drain. The Color Out of Space leshy drains the color in the space it occupies, forcing all creatures in its space to make a DC 15 Dexterity saving throw or suffer 13 (3d8) necrotic damage on a failure or half as much on a successful one. The swarm heals by half the total damage dealt.
  • Alien Spray. The Color Out of Space Swarm releases a prism of alien light in a 30-foot cone. Each creature in the area rolls 1d6 on the table below to determine which beams affects them, then attempts a DC 15 saving throw of the indicated type. On a successful save, the listed effect is negated entirely.


The Color Out of Space derives from Lovecraftian Mythos, making it possible that the Outer Gods are somehow responsible for the Color Out of Space and its subsequent leshies.

Any that dare to face these leshies should be aware that they tamper with powers and plans beyond any understanding, the ramifications of which may be dire.

If terrestrial forces are responsible for the creation of this bizarre leshy, no records remain. The Color Out of Space (Color Out of Space) Leshy Swarm is unlike anything else on the planet. Formed from seemingly normal plants, but grown to an unnatural size, the creatures of the swarm are nearly impossible to comprehend. Mortals have trouble even viewing the swarm, their eyes sliding off the overlapping alien colors. The machinations and motivations of this creature are as unknowable as the leshy itself. What is known is that this swarm seeks to spread its touch, draining the color of other plants and adding to its own numbers.
