  • False Appearance. While the chromatic toadstool remains motionless, it is indistinguishable from an ordinary fungus.
  • Hive Mind. All fungi within 50 miles of are in constant communication. If one is aware of a particular danger, they all are. No fungus in a group is considered surprised unless all of them are.
  • Variable Illumination. The chromatic toadstool glows, shedding bright light in a 5-foot radius and dim light for an additional 5 feet. When stepped on, the chromatic toadstool glows brighter, shedding bright light for 1d4 rounds in a 10-foot radius and dim light for an additional 10 feet.


  • Multiattack. The chromatic toadstool makes four Chromatic Mycelium attacks.
  • Chromatic Mycelium. Melee Weapon Attack: +4 to hit, reach 10 ft., one creature. Hit: 6 (1d8 + 2) damage. The damage type is determined by the color of the chromatic toadstool: blue (cold), red (fire), green (acid), pink (radiant), yellow (lightning), violet (psychic).


This softly-glowing toadstool has a cap that is ten-feet in diameter and brightly colored.

Chromatic toadstools are plants cultivated by animated fungal colonies to act as guardians to their territory. By stepping on chromatic toadstools in a certain color order, they are harmless, but for intruders unaware of their pattern, they can be deadly.

Chromatic toadstools live in acidic swamps are immune to the corrosive effects surrounding them, which makes it very appealing for large creatures to walk across their surface. If a creature attempts to swim beneath the toadstool in the acid, or steps on the colors out of order (coded by their fungal masters, usually a queen), the toadstool unfurls mycelium from its underside, where they normally remain hidden in the gills.
