The Saltspire Salt Mine spoils its rock outside the galleries, and the heaps stand in long grey ridges a man could mistake for landscape. The lurkers mistake nothing. They lie under the tailings breathing through the loose stone and they hunt by footfall alone, which is why mine company survey walks are paced on planking and why the plank roads have no gaps in them. Every gap is a story.

Traits

Spoil Shroud. While burrowed in loose tailings, gravel, or sand, the lurker is hidden even from creatures with darkvision and blindsight; the only warning is a line of settling stones.

Vibration Sense. The lurker automatically detects any creature moving across loose ground within its tremorsense. A creature standing still, or moving on solid stone or planking, cannot be sensed by it at all.

Pack Ambush. The first lurker to hit a surprised creature gives every other lurker advantage on attack rolls against that creature until the end of its next turn.

Actions

Multiattack. The lurker makes two claw attacks.

Claw. Melee Attack Roll: +5, reach 5 ft. Hit: 10 (2d6 + 3) Slashing damage, and the target is grappled (escape DC 13) if it is Medium or smaller. The lurker has two claws, each of which can grapple only one creature.

Drag Under. One Medium or smaller creature grappled by the lurker is pulled into the tailings with it. A buried creature is restrained and begins holding its breath, and the collapsed spoil fills the hole behind it. Digging a buried creature free takes three workers 3 rounds, or one worker a DC 13 Strength (Athletics) check as an action.
