Traits

Aura of Bioluminescent Fog.A 30-foot-radius cloud of blue fog surrounds the Goliath. The area is heavily obscured for creatures other than the Goliath. Any creature that starts its turn in the area must succeed on a DC 17 Wisdom saving throw or be Frightened for 1 minute as they perceive their allies as monsters. A creature can repeat the saving throw at the end of each of its turns.

Caustic Splashback.When a creature within 5 feet of the Goliath hits it with a melee attack, the Goliath sprays pressurized Blue Bile. The attacker must make a DC 17 Dexterity saving throw, taking 10 (3d6) acid damage on a failed save, or half as much on a success. If the save fails, the creature's AC is reduced by 1 until the armor is cleaned or repaired as the fungus accelerates growth.

Siege Monster.The Goliath deals double damage to objects and structures.

Regeneration.The Goliath regains 10 hit points at the start of its turn. If it takes fire or cold damage, this trait doesn't function at the start of the Goliath's next turn. The Goliath dies only if it starts its turn with 0 hit points and doesn't regenerate.

Actions

Multiattack.The Goliath makes two Claw attacks. It can replace one Claw attack with a Maw attack if it has a target grappled.

Claw.Melee Weapon Attack: +10 to hit, reach 15 ft., one target. Hit: 19 (3d8 + 6) slashing damage plus 7 (2d6) necrotic damage. The target is Grappled (escape DC 18) if it is a Huge or smaller creature. The Goliath has two claws, each of which can grapple one target.

Maw.Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 22 (3d10 + 6) piercing damage. If the target is a creature, it must succeed on a DC 17 Constitution saving throw or be infected with Spore-Born blight. While infected, the creature's speed is halved and it cannot regain hit points. The infection lasts until removed by a Lesser Restoration spell or similar magic.

Exhale Aether-Fog (Recharge 5–6).The Goliath exhales a 60-foot cone of concentrated spores. Each creature in that area must make a DC 17 Constitution saving throw, taking 45 (10d8) necrotic damage on a failed save, or half as much damage on a successful one. Creatures that die from this damage rise 1 minute later as a Spore-Cougher Swarm under the Goliath's control.

Spore-Born Titan

The Spore-Born Titan is the terrifying culmination of the mycelial lifecycle—a goblin that has refused to die, surviving for centuries as an "old growth" organism until it transcends its small, feral origins to become a hill-sized engine of biological assimilation. This apex organism represents the final, grotesque metamorphosis of a creature consumed by the Omnisporangium (known to some as Mycelia-Zul, The World-Root). Its body is a grand, mythic fusion of necrotic muscle and hardened, bark-like fungal plates that groan like rusted iron with every movement. Where a face should be, a cavernous, toothless maw exhales a constant, rolling tide of bioluminescent blue fog, while its limbs—thick as ancient oaks—end in grasping, multi-jointed claws capable of crushing stone.

Far from a dormant sleeper, the Titan serves as a mobile broadcast tower for the hivemind, anchoring its influence across the forest floor and rhythmic industrial centers. In the ecology of the Azure Awakening and the Cicadan Swarm Genesis, the Titan is a mobile siege engine. It does not merely inhabit an environment; it terraforms it. As it walks, its massive feet leave behind "fertile" footprints where Spore-Cougher Swarms gestate in minutes. It is the apex predator of the Viridian Cradle, acting as a shepherd for the goblin hive-mind and a nightmare for the surface world.

"The mountain does not just walk; it breathes. And in its breath, I heard the names of everyone we lost, harmonized into a single, shimmering chord of blue." — Master Artificer Harlen of Steamfort

Sight, Sound, and Smell

The Titan appears as a shimmering silhouette of cobalt fog and calcified plates, its massive form illuminated by internal veins of pulsing Blue Bile. The sound is a rhythmic, low-frequency thrumming—a biological heartbeat that mimics the hiss of a massive steam engine. The air surrounding it carries the ancient, heavy scent of damp loam and ozone, undercut by the sharp, metallic tang of concentrated Aether.

Lore & Origin

The Spore-Born Titan is the ultimate expression of the Equilibrium Cycle, a biological rebalancing that occurs every 17 years. While smaller vessels like Whisper-Hulks are formed from giant-kin, the Titan is a rare "Perfect Vessel." It begins when an Aether-Weaver Goblin is injected with an excessive concentration of Blue Bile. Instead of expiring, the host's Aether metabolism accelerates, weaving mycelial threads through every nerve ending until the individual ego is extinguished, replaced by the collective resonance of the World-Root.

Historically, these Goliaths have appeared during periods of rapid surface expansion. Scholars at Thorne’s Library believe the Titans are the world’s "mobile immune cells," triggered by the "Aether-Scald" produced by industrial hubs like Steamfort. To the Titan, the rhythmic clanging of clockwork and the smog of the Steam Wrights Consortium are symptoms of a planetary infection that must be "pruned" and processed back into the earth.

Tactics

The Spore-Born Titan does not carry victims internally; rather, its expansive, ropy tendrils lash out to ensnare prey, externally fusing them into its own mass. In combat, it uses its Bioluminescent Fog to hijack the senses of its enemies, making them perceive their allies as rotting husks or industrial monsters. It prioritizes targets carrying high concentrations of magic or technology, sensing the "heat" of Aether like a predator senses blood. If damaged by heavy weaponry, it may trigger a Caustic Splashback, spraying pressurized Blue Bile that accelerates fungal growth on armor and skin alike.

Ecology

As a primary node in the Mycelial Threading network, the Titan acts as a conduit for the Omnisporangium’s telepathic signals. It often travels toward Bile-Ducts or geothermal vents to "recharge" its internal pressure. It is frequently accompanied by a frantic escort of Bile-Mutated Trolls and Aether-Weaver Goblins, who view the Titan as a walking god. Its presence stabilizes the local fungal bloom, ensuring that the 17-year timer of the Cicadan Swarm remains perfectly synchronized.

Ideals & Flaws

Ideal: Harmony. "The chaotic screams of the surface must be tuned to the singular, silent song of the Root."
Flaw: Over-Specialization. The Titan is so attuned to the resonance of Mycelia-Zul that it is momentarily blinded and deafened by the "harmonic stabilizer" effects of the Eclipse Sun-Spore Seed.

Rumors & Whispers

True: Every 17 years, the Titans converge on a single location to form a "Heart-Stalk," which can signal a planetary cataclysm similar to the Great Flood.
False: The Titans are ancient clockwork constructs from the First Age that have simply been overgrown by mushrooms.

Markings

Commonly found on the outskirts of settlements the Titan approaches, or scratched into the copper plating of Steamfort's outer walls:

The Mark: A gear being cracked open by a sprouting seedling.
Translation: "The cog must bleed to feed the root; the silence is coming."

Secret Motivation: The Spore-Born Titan is driven by a directive of "Holy Architecture." It seeks to find "Perfect Anchors"—locations of intense energy, such as the geothermal vents of Steamfort. Once found, the Titan intends to undergo its final metamorphosis: rooting itself permanently to the earth to become a new Deep-Root Hub. It views the screams of those it assimilates not as cries of pain, but as the chaotic tuning of an orchestra finally finding its harmony.

Adventure Hook: The Siege of Oakhaven Rumors have reached Kigum of a "walking mountain" that has settled in the valley north of the city. The trade routes have been severed by a forest that grew overnight. Survivors speak of a Titan that has "sat down" in the center of a major logging village. It isn't attacking; instead, it is gently pinning villagers with tendrils, feeding them hallucinogenic spores to keep them in a state of euphoric paralysis while it weaves their nervous systems into its own. Lady Elara fears that if the Titan finishes rooting, the blue fog will become permanent. She offers a king's ransom to anyone who can "sever the heart-root" or use a hybrid seed to re-tune the creature's alien mind.
