  • Skilled Explorer. The spore rat ignores nonmagical difficult terrain created by plants. The spore rat also has advantage on saving throws against spells and magical effects involving plants.


  • Infectious Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 5 (1d4 + 3) piercing damage. The creature must make a DC 10 Constitution saving throw or be poisoned until the end of its next turn.
  • Spore Cloud (2/day). The spore rat releases a cloud of toxic spores within a five-foot radius. All creatures adjacent to the spore rat must make a DC 10 Constitution saving throw or have its Strength score reduced by 1d4. The creature dies if this reduces its Strength to 0. Otherwise, the reduction lasts until the target finishes a short or long rest.


We were chasing wererats through the sewers when we came upon another pack of giant rats. More of an annoyance than a threat to experienced sewer runners like us, but these were unlike any giant rats we had ever seen. Their fur was more green than brown, and it had an odd texture. They came swarming toward us, and we readied ourselves. As they neared, the rats spurted out clouds of choking spores that filled the narrow sewer. It was close, and we learned not to underestimate rats again. Ultär, son of Ultär, adventurer

These dog-sized rats are covered in greenish-brown growths that mat to form a fur-like covering. This mat is not fur; it is a colony of dozens of species of fungi and mosses. These colonies give them a distinct advantage when attacking: Their bites inject poison spores into their prey and if threatened, the spore rat can unleash a cloud of choking spores. Spore rats behave much like other giant rats, living in large packs, making nests in forgotten or out-of-the-way places, and opportunistically feeding on anything they find.
