The fountain feeds the garden.
After defeating the Zehir acolytes, The Mighty Nein puzzled their way below the temple fountain into the underground tree grove. Fed a steady diet of sacrificial blood, these trees produce a fruit that primarily feeds the guardian of one of the locked seals of Uk’otoa, and secondarily acts as a hallucinogen for humanoids (and possibly yuan-ti). In rooms off of the grove were hatcheries for unknown reptiles, and the path to the warden. Naturally, the room was not without protection against intruders, as Nott discovered when she disturbed the sentient vines hiding among the other garden floor greenery.
The garden feeds the warden.
Though simple beings, these vines could do a lot of damage in a short amount of time. Their initial strangle attack damaged, grappled, and restrained its target. After a successful strangle, the vine employed its thorns, which dealt an alarming amount of poison damage both on its turn and on the turn of its prey. Poor Nott got to experience all of the vine’s attacks, falling unconscious after taking more poison damage at the top of her turn. Fjord managed to be strangled by the other vine, but was saved from taking any further damage by enlarged-Jester’s Sacred Flame.
