Reedmaw Snare

• Reed Snare (Melee Weapon Attack: +5 to hit, reach 10 ft., one creature. Hit: 8 (2d4+3) bludgeoning damage, and the target is grappled (escape DC 13) if it is Large or smaller. Until the grapple ends, the target is restrained.
• Drag (Str save DC 13): If the Reedmaw Snare succeeds on a grapple check against a restrained creature, it drags the target 5 feet toward the waterline.
• Drowning Coil (bonus action, only vs. a creature it has grappled and that is fully submerged): The target must succeed on a DC 13 Constitution saving throw or begin suffocating.

• False Appearance: While motionless, the Reedmaw Snare is indistinguishable from an ordinary patch of swamp reeds. Creatures must succeed on a DC 15 Wisdom (Perception) check to notice it before it attacks.
• Silty Camouflage: The Reedmaw Snare has advantage on Dexterity (Stealth) checks made while in swampy or marshy terrain.
• Rooted Fury: The Reedmaw Snare cannot move its position on the ground, but its reeds can lash out to a reach of 10 feet.
• Vulnerable to Fire: The Reedmaw Snare takes double damage from fire.
• Amphibious: The Reedmaw Snare can breathe air and water.

Travelers who cross the Murkfen call it 'the patch that waits.' What looks like an unremarkable stand of brown reeds swaying in the wind is in fact a single vast root-creature, its stalks fused into whip-like tendrils and its true bulk submerged in the muck below. It does not hunt so much as wait for centuries, feeding on whatever wanders close enough to test the water's depth. Local guides mark safe fords with strings of bone charms — not for luck, but because the Reedmaw Snare, sensing the scent of old blood on bone, tends to avoid patches already claimed by another predator's kill.
