Magical Dungeon Fungus

Dwarven and Tenderfoot (Halfling) druids and clerics in my game world often specialize in magical fungi. They learn how to find and cultivate these fungi the same as above ground mates create potions. There are some subtle differences.


This is a mold that appears on almost anything in a dungeon in a two to five foot spread; it is non-sentient, and comes in a multitude of colours which reflects their magic and origin. It radiates a faint magical effect within a forty foot radius.  When either scratched or consumed it has a magical effect based on its colour. If consumed, the creature must make a Fort Save DC 11 or take 1d3 temporary constitution damage for 20 minutes. One gets the benefit whether one beats the poison effect or not. Many types do not need to be consumed, some just need to be breathed into the body. If one does not breathe or eat, such as a construct, the fungus has no potential effect.

If scrapped off from the object, the magic fades in 10d10 rounds and the entire fungus slowly fades. Some alchemists or underground druids have vials that can prolong the fungus indefinitely. Underground druids often try to keep these molds locations secret, as they can be perpetual sources of magic if they are properly harvested. Unfortunately, above ground humanoids just scratch the fungus, and release the magic in a one shot, instead of utilizing them over periods of time; those who understand the difference find this very wasteful on principle.

They are sold at around the same price points as magical potions. They can be enhanced, but via a secret known to underground druids or dwarven brew masters.

These are just the most common types of fungus known, there are many others.

Blue Fungus – healing, 1d6. Can work if the creature has been dead for less than one minute. If consumed twice or more in 24 hours, the second dose inflicts 2d8 damage, no save.
