Moonpetal Tarn
Palakar Forest · Primary antidote site · Ooze-guarded root intake
Pale moonpetals drift across a tarn as still as polished silver. Beneath them, black-and-gold veins branch through the sediment toward a tangle of exposed roots. A small gelatinous shape drifts through the shallows, carrying silt and fallen petals within its translucent body. Beyond the pool, a far larger patch of glossy green growth bulges among the reeds. The reeds bend toward it, though there is no breeze.
GM — The Contaminated Root Intake
Primary antidote site. The Moonpetal Tarn collects water feeding roots closer to the central Stage 3 blightnode. The infernal infection is established in the submerged sediment and living root intake, not merely in the surface water. The surviving pale blossoms mask how far the corruption has spread. A dose splashed over the water's surface is wasted; the prepared Watercourse Neutralizer must reach the infected root intake. Treat the objective as a careful placement rather than a requirement to destroy every creature.
Occupants — Two Oozes
Gutter Ooze (Creature −1): This Tiny ooze drifts through the silt and shallow water, gathering petals and organic detritus. It is a minor physical obstacle near the accessible bank. It is mindless, not a deliberate guardian; disturbed water or nearby movement may draw it in. Its Slip Up reaction can make footing treacherous.
Verdurous Ooze (Creature 6): This far more dangerous Medium ooze lurks amid the reeds and overhanging roots on the far side of the tarn. Its motion sense 60 feet detects movement and vibration even without sight. Its 20-foot Enliven Foliage aura turns the vegetation into grasping difficult terrain. The creature is mindless and acts on motion and prey rather than infernal loyalty. Its corrosive body, Grab, and Sleep Gas make close combat extremely hazardous for low-level PCs.
Encounter warning: A level-6 creature is four levels above a level-2 party and represents extreme danger even alone. Do not treat this as an ordinary fight. Make the large ooze visible through its effects on surrounding plants before characters enter its reach. It should remain in its own portion of the tarn unless disturbed or attracted by motion; players can choose to return later if they cannot secure a viable approach.
Exploration and Approach
- Scout the pool: From the edge, the party can identify the silt-buried root intake and see repeated movement through the reeds. Nature DC 18 identifies the black-gold channels as infected living roots, not harmless discoloration.
- Choose a bank: A shallow near-bank channel offers an approach to one exposed intake without crossing the deepest water. The larger ooze's position and 60-foot motion sense remain important; cover and concealment alone do not block its motion sense. Players may wait until it shifts away or find ways to avoid causing detectable movement.
- Manage the small ooze: The Gutter Ooze may be distracted by organic debris or dealt with separately. It should not automatically summon the Verdurous Ooze as a scripted reinforcement.
- Withdraw: The party can retreat with the site identified and return with better preparations. Combat is not required to earn the reconnaissance clue.
Primary Objective — Deliver the Antidote
one prepared Watercourse Neutralizer dose must be introduced directly into the infected root intake beneath the silt. Characters must physically reach an accessible intake and seat or pour the antidote where it contacts infected living roots. Sprinkling the surface of the tarn does not work.
If the site is secure: Careful placement takes 10 minutes, with no check required. Under pressure: Nature DC 18 or Crafting DC 18 permits rapid placement in approximately 2 minutes, using the attached Neutralizer Placement — Moonpetal Tarn challenge. Failure costs time or requires repositioning, rather than automatically consuming a dose. A single successful placement treats this site; there is no requirement to administer a separate dose to each ooze.
The antidote threads into the submerged rootlets. For a moment the black-gold veins glow brighter, then collapse into dull gray strands. A ripple travels across the pool, and the moonpetals slowly settle into still water again.
Resolution and Consequences
Successful treatment dims the golden filaments and arrests the local seep toward the inner woods. It does not cleanse the central Stage 3 blightnode or automatically kill, pacify, or remove the two oozes. Record Moonpetal Tarn: Treated and note whether the creatures remain. If the party withdraws before delivering the antidote, the root intake stays infected.
Report the contaminated intake, the two oozes, and whether the antidote reached the living roots. Thornwatch can use that information to protect water supplies and plan a safer return; the broader root network still requires treatment elsewhere.
This location uses the Watercourse Neutralizer, a custom field preparation for contaminated groundwater and infected root intakes. Use one watercourse dose per water site; a dose must reach the living feeder roots, not merely splash into open water. It suppresses the local contamination but cannot destroy an exposed infernal blightseed. The separate Blightseed Antidote treats seed cores directly and is not interchangeable. Treat all application timings and DCs here as scenario-specific skill challenges, not universal PF2e consumable rules.
