The tapeworm’s larger, more malicious cousin.
Glutton worms find their way into the body through contaminated food, taking up residence in the host’s digestive tract. The worms often grow so large as to entirely block one’s intestines, even to the point of distending the host’s belly, such that no sustenance gets through the host without the worm first taking its share – a large share indeed. If left unsatisfied, it will 10 instead leech from the host’s body instead, forcing the afflicted to meet its ravenous demands or find themselves being drained of nutrients and energy.
In certain parts of the world, these worms are unheard of; the worm has a particular dislike for a certain beverage, coffee (or anything caffeinated), and will voluntarily expel itself from the host if exposed to enough of it. While an unpleasant experience for all parties, the treatment is rapid and absolute, returning the host’s bowels to normal, once their stomach settles. Exposure occurs through consumption of contaminated food or water.
On consumption, a humanoid must succeed in a DC 10 Constitution save or the worm finds a home in their gut. While infected, triple rations/food must be consumed to keep the worm happy. If less is consumed, it will leech from the body, forcing a DC 15 Constitution save each day, failure of which gives the character 1 Exhaustion.
Consumption of copious amounts of coffee or any other caffeinated substance in a single day will purge the worm.
