Siltbound Monk - AI-generated fantasy Monster

Siltbound Monk

The guardian was once Sister Mereth, a monastic sentinel assigned to patrol the lower halls during the bell crypt's sealing. When blackwater began leaking through the crypt foundations, she remained at her post after the other guardians fled or died. The water changed her body but preserved enough of her discipline to trap her in an endless patrol. The evidence of her former identity survives in repeated initials carved beside patrol doors, a prayer ring in a ruined alcove, and a hymn preserved inside a wax-sealed reliquary.

Amphibious. The monk can breathe air and water.
Siltbound Concealment. The monk has advantage on Dexterity (Stealth) checks made while submerged or behind hanging chains, broken doors, or similar flooded-corridor cover.
Floodwalker. The monk ignores difficult terrain caused by shallow or waist-deep water. Other creatures in waist-deep water treat it as difficult terrain unless they have a swim speed.
Blackwater Grip. When the monk starts its turn grappling a creature in water, it deals 3 () necrotic damage to that creature and can pull it up to 5 feet toward deeper water.
Fragments of Duty. The monk has advantage on saving throws against being charmed or frightened. If shown the monastery insignia or presented with the preserved hymn, it loses this advantage and cannot use reactions until the end of its next turn.
Final Patrol. The monk has advantage on initiative checks while in the monastery and knows the location of every active trap along its patrol route.
Multiattack. The Siltbound Monk makes two Rusted Chain attacks or one Rusted Chain attack and one Blackwater Palm attack.
Rusted Chain. Melee Weapon Attack: to hit, reach 10 ft., one target. Hit: 8 () slashing damage. If the target is Large or smaller, it must succeed on a Strength saving throw or be grappled. The grappled target's escape DC is 14. Until this grapple ends, the monk cannot use the chain against another target.
Blackwater Palm. Melee Weapon Attack: to hit, reach 5 ft., one creature. Hit: 10 () bludgeoning damage, and the target must succeed on a Constitution saving throw or be unable to take reactions until the end of its next turn. If the target is grappled by the monk, it is also pulled up to 5 feet into an unoccupied space in the monk's flooded corridor.
Cryptwater Breath. The monk exhales a plume of oily water in a 15-foot cone. Each creature in the area must make a Constitution saving throw, taking 14 () necrotic damage on a failed save, or half as much damage on a successful one. A creature that fails is also blinded until the end of its next turn.
Patrol-Step. The monk chooses one creature it can see within 30 feet that is standing in water, adjacent to a hanging chain, or within 5 feet of a broken door. The monk moves up to 15 feet without provoking opportunity attacks, provided it ends this movement in water or behind cover. It can then make one Rusted Chain attack.
Waterway Custodian. The monk strikes a submerged pressure plate, broken sluice, or hanging chain within 10 feet. One dungeon hazard connected to that feature activates, if available. Examples include raising the water level by 1 foot in the corridor, dropping a barred door, releasing a concealed current, or causing a bell-rope snare to tighten. If no hazard is available, the monk instead creates difficult terrain in a 10-foot-square area of shallow water until the end of its next turn.
Drag the Fallen. When a creature the monk can see falls prone or is pulled into water within 15 feet, the monk moves up to 10 feet toward that creature without provoking opportunity attacks. If it ends within reach, it can make one Rusted Chain attack.
