A healer's domain has been overtaken by fungal foes. Without help, a friend is doomed to a mycelial fate.

On June 25th, 2025, roughly 30 people convened in Columbus, Ohio at a Shadowdark dungeon-making seminar. A Fungal Problem is the resulting adventure. 

The party arrives at a temple to pick up their comrade and pay for their friend's new arm. The necromancer there grows limbs to use as replacements, but something has gotten out of hand and fungus has taken over the temple. What else could the necromancer be hiding?

This nine-area dungeon designed for low-level characters works great as a one-shot or to drop into a campaign. Don't own Shadowdark? This adventure can be played using just the free quickstart set!
