Rooted Fortress. The Spore-Father cannot be moved by any means short of a Wish spell. It automatically succeeds on Strength and Dexterity saving throws against effects that would move it or knock it prone.
Fungal Apotheosis. The Spore-Father can concentrate on two spells at once. If it takes damage, it makes a single Constitution saving throw to maintain concentration on both.
Spore Leak. Whenever the Spore-Father takes fire damage, it releases a cloud of irritating smoke. All creatures within 20 feet must succeed on a Constitution saving throw or be Blinded until the end of their next turn.

Spells

Blight (level 4, necromancy). Deals necrotic damage to one creature.
Entangle (level 1, conjuration). Grasping weeds and vines turn the ground into difficult terrain.
Cloudkill (level 5, conjuration). A 20-foot-radius sphere of poisonous, yellow-green fog.

Actions

Multiattack. The Spore-Father makes three Root Lash attacks.
Root Lash. Melee Weapon Attack: to hit, reach 20 ft., one target. Hit: 14 () bludgeoning damage plus 7 () necrotic damage. If the target is a creature, it is Grappled (escape ).
Reclaim the Flesh. One creature grappled by the Spore-Father must make a Constitution saving throw, taking 35 () necrotic damage on a failed save, or half as much on a success. The Spore-Father regains hit points equal to half the necrotic damage dealt.

Reactions

Spasm Response. When a creature hit the Spore-Father with a melee attack, the Spore-Father can trigger a localized puff of spores. The attacker must make a Constitution saving throw or be Poisoned until the end of its next turn.

Legendary Actions

Release Spores: Confusion. The Spore-Father releases a haze of iridescent spores. Each creature within 30 feet must succeed on a Wisdom saving throw or be affected by the Confusion spell until the end of its next turn.
Release Spores: Slow. Each creature within 30 feet must succeed on a Wisdom saving throw or be affected by the Slow spell until the end of its next turn.
Release Spores: Blindness. Each creature within 30 feet must succeed on a Constitution saving throw or be Blinded until the end of its next turn.
Cultivate Hulk (costs 2 actions). The Spore-Father causes a Moss-Stitched Hulk to rise from the ground in an unoccupied space within 60 feet. The Hulk acts on its own initiative. Only three Hulks can exist at one time.

Augmentations

Fungal Symbiosis: Grants the entity the ability to ignore exhaustion and feed on ambient decay.

Notes for the game master

The Spore-Father is a stationary boss; encounter design should provide cover for players to avoid his spores while closing the distance.
Moss-Stitched Hulks use the Ogre Zombie statblock but are considered Plants and have a climbing speed of 20 ft.

Tactics

  1. Opening

    The Spore-Father begins by casting Entangle and Cloudkill to divide the party and restrict movement while summoning the first Moss-Stitched Hulk.

  2. Mid-fight

    He uses Legendary Actions to cycle between Confusion and Slow to prevent the party from effectively attacking the main body. He targets healers with Blight.

  3. End of the fight

    When reduced to 50 hit points, he uses Reclaim the Flesh aggressively to keep himself alive while focusing on Blindness spores to disable ranged attackers.

  4. Retreat

    The Spore-Father cannot flee. He will continue to summon Hulks and lash out until his central mass is destroyed.

How it fights

Prioritize grappling high-mobility targets with Root Lash.
Use Confusion spores if more than two enemies are within range.
Always maintain a Hulk between himself and the strongest melee combatant.

Who it attacks first

Clerics and Druids (who can dispel his effects)
Ranged attackers (who can strike from outside his tremor sense)
Nearby melee targets (to use Reclaim the Flesh)

Works well with

Works well with Myconids or Shambling Mounds who are immune to his spores.
Can be paired with lair traps like falling stalactites or gas pockets.

How to beat it

Fire damage (exploits his weakness but triggers Spore Leak).
Dispel Magic or Greater Restoration (clears spore effects).
Ranged attacks from 65 feet or further (beyond his normal spore range).

Ways to avoid a fight

The Spore-Father may bargain if the party offers high-quality 'compost' (fresh bodies of powerful beings).
A druid might use a high-level Persuasion or Nature check to lull him into a temporary dormancy.

Ecology

A colossal, pallid puffball fungus dominates the center of the sanctum, its surface pulsating with rhythmic, bioluminescent veins of toxic green. From the fungal mass, the upper torso of an ancient priest protrudes, draped in rotting, moss-encrusted vestments. The priest's eyes are replaced by tiny, glowing mushrooms, and its mouth is sewn shut with fungal threads.

Behavior

The Spore-Father does not move. It communicates through telepathic whispers that sound like rustling dry leaves. It views itself as a gardener of souls, recycling the dead into a lush, suffocating eternity.

How it lives

As a symbiotic entity between a high-level necrotic caster and a Great Puffball, it feeds on the decay of a mass grave. It purifies the rot into magical energy, which it uses to sprout its Moss-Stitched Hulks.

Lair

The Spore-Father is the lair itself. Roots permeate the stone walls, and the floor is a deep pile of composted bone and moss. Thick spores choke the air, dimming all light sources.

Habitat
The Verdant Sanctum, a deep subterranean dungeon located beneath a prehistoric burial ground.

Lore

Centuries ago, High Priest Malakor sought immortality by merging with the cycle of decay. He succeeded far too well. Now known as the Spore-Father, he sits atop the 'Ever-Grave,' orchestrating a slow, green apocalypse. Adventurers are merely fresh fertilizer for his expansion.

What drives it

To expand the Verdant Sanctum until the surface world is consumed by the 'Great Rot' and reborn as a silent, fungal paradise.

After the fight

Upon its death, the Spore-Father bursts in a harmless shower of white dust. The plants in the dungeon rapidly wither and die, leaving behind a massive pit filled with centuries of cleaned, white bone. The corruption in the surrounding forest begins to fade.
