Watercourse Neutralizer Placement — Fernmirror Pool
Watercourse Neutralizer Placement — Fernmirror Pool
Optionally close the secondary seep and stop Silverrun from being recontaminated through connected underground roots.
Without pressure: If guards are absent and the party has access to the intake, placing a Watercourse Neutralizer dose takes 10 minutes and requires no check. Under pressure: use one of the following checks to place it within about 2 minutes; a failed attempt costs time, never automatically destroys the watercourse dose.

Afterward: The mirrorlike surface breaks into ordinary ripples and the pooled gold recedes. Optional objective. If the party lacks a fourth dose, they can simply map this seep for later treatment by Cedar Court specialists. The mature central node remains active until the final assault.
Distinct formulas
Only Watercourse Neutralizer works at this feeder intake. It cannot kill individual blightseeds. A Blightseed Antidote dose is a different preparation and does not substitute here. This 10-minute safe / approximately 2-minute pressured procedure is a custom scenario challenge (Nature or Crafting DC 18).
