Fungal Fortitude. If damage reduces the sentry to 0 hit points, it must make a Constitution saving throw with a DC of 5 + the damage taken, unless the damage is fire or from a critical hit. On a success, the sentry drops to 1 hit point instead.
Stench of Decay. Any creature that starts its turn within 5 feet of the sentry must succeed on a Constitution saving throw or be poisoned until the start of its next turn.

Actions

Multiattack. The sentry makes two attacks with its fungal halberd.
Fungal Halberd. Melee Weapon Attack: to hit, reach 10 ft., one target. Hit: 8 () slashing damage plus 3 () necrotic damage. The target must succeed on a Constitution saving throw or have its maximum hit points reduced by an amount equal to the necrotic damage taken.

Reactions

Release Cloud. When the sentry takes damage, it releases a puff of toxic spores. Each creature within 10 feet of the sentry must make a Constitution saving throw. On a failure, a creature takes 7 () poison damage and the area is heavily obscured by black spores until the end of the sentry's next turn. On a success, the creature takes half damage and is not blinded.

Gear

  • Rusted Fused Plate (Armor, None)Armor that has become part of the wearer's anatomy.
  • Spore-Dipped Halberd (Weapon, 20 gp)A heavy polearm coated in necro-fungal sludge.

Notes for the game master

The spore cloud effect stacks with the Stench of Decay for a punishing melee experience.
Fire damage bypasses the Fungal Fortitude and prevents the Spore Cloud from triggering.

Tactics

  1. Opening

    The sentry stands motionless until a target is within 10 feet, then it uses its Reach advantage to strike first.

  2. Mid-fight

    It relies on its 'Release Cloud' reaction to punish attackers and obscure the battlefield, making it harder for ranged attackers to hit it.

  3. End of the fight

    It fights until it is completely destroyed, never retreating from its post.

  4. Retreat

    The sentry has no morale and cannot be intimidated. It will stand its ground even against overwhelming odds.

How it fights

Uses its 10ft reach to hit enemies before they can get into melee range.
Stays in narrow hallways where its spore cloud can block the entire passage.

Who it attacks first

Clerics or Paladins who might use radiant or fire energy.
The nearest living creature that is not yet infected.

Works well with

Violet Fungus: The sentry keeps players busy while the violet fungus rots them.
Will-o'-Wisps: These lure players into the sentry's reach in the dark.

How to beat it

Ranged fire attacks (Fire Bolt, Flaming Arrows).
Gust of Wind or Fog Cloud to clear the spores.

Ways to avoid a fight

Wearing a damp cloth over the face grants advantage on saves against the spores.
Tossing a high-concentration salt bag at the sentry may distract the fungus, making it sluggish for 1 round.

Ecology

A skeletal figure standing six feet tall, though its bones are barely visible beneath a thick carpet of pulsating black filaments. Rusted iron plate armor is physically fused into its desiccated flesh by weeping fungal roots. In place of eyes, twin clusters of pale white mushrooms sprout from its sockets. It grips a massive, pitted halberd that drips with a dark, oily substance.

Behavior

The sentry stands perfectly still until its designated perimeter is breached. It moves with a jerky, unnatural gait, as if the fungus is pulling the bones like a marionette. It does not speak, but emits a low, wet wheeze from its throat as spores leak from its joints.

How it lives

The Mold-Stuffed Sentry is the result of 'Black Grave-Cap' spores infecting a fresh corpse in a high-humidity environment. The fungus preserves the motor functions of the host to protect the main colony.

Lair

Usually found in damp, shaded alleyways or guard posts where moisture allows the fungal colony to thrive.

Habitat
Dreary country towns, ruined watchtowers, and foggy graveyard gates.

Signs that it is near

A heavy smell of damp earth and rot
Black soot-like residue on the ground
Mushrooms growing in the shape of human footprints

Lore

The village of Oakhaven fell in a single night, not to raiders, but to a rot that came with the autumn fog. The guards were the first to turn. Now they stand at the village limits, mindless and eternal, ensuring that those who stayed never leave, and those who arrive never depart.

What drives it

To stand guard over its original post and eliminate any living organisms that could provide new biomass for the fungal spread.

After the fight

Once defeated, the fungal filaments rapidly wither if exposed to direct sunlight, leaving behind only rusted scrap metal and brittle, bleached bones.

“Now they stand at the village limits, mindless and eternal, ensuring that those who stayed never leave, and those who arrive never depart.”
