Thornlash Lattice — Simple Hazard 2
Thornlash Lattice
Magical · Plant · Trap
Pale bark chips line a gap between two cedars. Above them, black thorns lie in a strangely regular weave, ready to snap across anyone forcing a way through.
Stealth DC 18 (trained) to notice tensioned shoulder-high thorns and hidden anchors.
Disable Nature DC 18 (trained) to release the living tethers, or Thievery DC 18 to pin the springing branches. Severing the anchors from a safe distance also stops the trap from resetting.
Trigger A creature pushes through the armed gap between the cedars.
Effect — Thornlash Branches rake a 10-foot line. All creatures in the line attempt a DC 18 basic Reflex save against 2d6 piercing damage. On a critical failure the creature is also immobilized until the end of its next turn (Escape DC 17 ends the effect early).
Reset The vines become taut again after 1 minute unless their anchor tethers are severed or safely disabled.
The Assassin Vine (Creature 3) inhabits lower roots beyond the trap; the Glimmervine (Creature 4) lurks deeper amid bright blossoms. Each has its own monster stat block and sensing abilities. Neither is an automatic reinforcement when this independent hazard triggers. Let careful PCs spot and bypass the lattice without triggering both plant encounters.
