Spore Song

From publisher blurb: Mini-Dungeon for 5 characters of level 3 Special Collaboration with Dynamic Dungeons! The characters must travel to the Underdark to collect a sample of spores purported to possess magical properties. A wizard or druid may have hired the party to gather the spores on their behalf, or perhaps the spores are the only known cure for a plague that has devastated the characters’ homeland.
