Bogroot Grasp — Simple Hazard 3
Bogroot Grasp
Environmental · Plant · Trap
Stealth DC 19 (trained) to notice black roots coiling beneath the mud rather than lying still.
Disable Nature DC 19 (trained) to coax the roots out of the crossing, or Survival DC 19 to find a clean path across the marsh.
Trigger A creature steps into the root-choked 10-foot patch of Goldfen mud.
Effect Roots lash the creature, which attempts a DC 20 Reflex save. Critical success: unaffected. Success: half of 2d6 bludgeoning damage. Failure: 2d6 bludgeoning damage and immobilized (Escape DC 18). Critical failure: 4d6 bludgeoning damage and immobilized.
Reset Roots slowly withdraw after 1 minute and may grasp again if the same patch is crossed.
GM Guidance. Tell players that the roots shift beneath the pads before anyone commits to the crossing; do not make this a compulsory surcharge on delivering the antidote. This is a custom campaign hazard; verify XP separately from the area monster roster.
