TRAITS

• Legendary Resistance (3/Day): If Gamigin fails a saving throw, he can choose to succeed instead.
• Magic Resistance: Gamigin has advantage on saving throws against spells and other magical effects.
• Soulcounter’s Sight: Gamigin can see the location and remaining lifespan of any creature’s soul within 120 feet of him. He also knows the true name and identity of any creature whose soul has passed into the Abyss, even if they are currently on another plane.
• Aura of Final Reckoning: Any creature within 60 feet of Gamigin must succeed on a DC 27 Constitution saving throw or suffer one level of exhaustion at the start of their turn. This aura also distorts time, causing creatures within it to move 10 feet slower than normal.
• Boiling Judgment (Recharge 5-6): As a reaction, when a creature within 30 feet of Gamigin makes an attack against him, he can cause a wave of energy from the Last Morass. The creature must make a DC 27 Constitution saving throw or take 90 (20d8) necrotic damage and become incapacitated until the end of its next turn. On a successful save, the creature takes half damage and is not incapacitated.

---

ACTIONS

• Multiattack: Gamigin makes three attacks: one with his Spirit Ledger, one with his Brush of Fate, and one with Divine Wrath.
• Spirit Ledger (Weapon Attack): Melee Weapon Attack: +18 to hit, reach 5 ft., one target.
  Hit: 50 (10d8 + 10) necrotic damage. On a critical hit, the target’s soul is briefly marked in the ledger, and they must make a DC 26 Wisdom saving throw or be cursed for 1 minute. While cursed, they cannot benefit from healing and must repeat the saving throw at the end of each of their turns.
• Brush of Fate (Weapon Attack): Melee Weapon Attack: +18 to hit, reach 5 ft., one target.
  Hit: 40 (8d8 + 10) magical slashing damage. On a hit, the brush leaves a mystical rune on the target, marking them for destruction. The next attack against the target has advantage. If the target is reduced to 0 hit points by this attack, their soul is immediately absorbed into the Last Morass, beyond resurrection.
• Divine Wrath (Recharge 5-6): Gamigin channels his chaotic power and strikes all creatures within 60 feet. Each creature must make a DC 27 Dexterity saving throw, taking 120 (20d12) force damage on a failed save, or half as much on a successful one. In addition, creatures that fail the saving throw are stunned until the end of Gamigin’s next turn.

---

LEGENDARY ACTIONS

Gamigin can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn. Gamigin regains spent legendary actions at the start of his turn.

• Soulrend (Costs 2 Actions): Gamigin targets one creature within 60 feet that has been marked by his Spirit Ledger. The target must make a DC 27 Constitution saving throw or take 90 (20d8) necrotic damage, and their soul is temporarily ripped from their body, causing them to be incapacitated until the end of Gamigin’s next turn.
• Command Servants (Costs 2 Actions): Gamigin summons a Demon Servant (use the statistics of a Vrock or Balgura, depending on the surroundings). The summoned demon takes its turn immediately after Gamigin’s legendary action. It remains under his control for 1 hour or until destroyed.
• Rite of Tar (Costs 3 Actions): Gamigin can open a small portal to the Last Morass and unleash a blast of boiling tar in a 30-foot cone. Creatures within the area must make a DC 27 Dexterity saving throw, taking 60 (10d10) necrotic damage and being restrained by the tar until they break free with a successful DC 27 Strength or Dexterity check at the end of their turns.

Additional Spell-Like Abilities (Legendary Actions/Innate Powers)

1. Soul Siphon (Recharge 5-6):
   • Range: 30 ft.
   • Effect: Gamigin can drain the life force of a creature within range. The target must make a DC 22 Constitution saving throw or take 5d10 necrotic damage. On a failed save, Gamigin regains half of the damage dealt as hit points. If the target is reduced to 0 HP by this ability, its soul is consumed by Gamigin, adding to his power.
2. Reckoning of the Abyss (Recharge 5-6):
   • Effect: Once per day, Gamigin can cast a Legendary Action to invoke the Abyss’s power, causing a 30-foot radius of darkness to emerge around him. All creatures within the area must make a DC 26 Wisdom saving throw or be paralyzed for 1 minute as they are overwhelmed by the forces of the Abyss.
3. Abyssal Mastery (1/Day):
   • Effect: Gamigin can invoke his Aura of the Abyss to distort reality itself. For 1 minute, he gains advantage on all attack rolls and saving throws, and all creatures within 60 feet of him must make a DC 24 Charisma saving throw or suffer disadvantage on attack rolls, ability checks, and saving throws for the duration.

REGIONAL EFFECTS

The region surrounding Gamigin’s Citadel (the Jagged Tor of Final Reckoning) is warped by his presence. These effects are noticeable within a 10-mile radius of the citadel:

• Time Distortion: Time passes erratically, with hours slipping by unnoticed or fast-forwarding without warning. This affects creatures’ sleep cycles and the ability to track time effectively.
• Necrotic Clouds: The air is thick with poison and necrotic energy, causing creatures who stay in the area for more than 24 hours to suffer one level of exhaustion every day.
• Soul Distortion: The souls of recently deceased creatures become visible, flickering in the sky like fading stars. These souls are drawn to Gamigin’s citadel, often finding themselves trapped in a loop of torment.

LORE AND ROLE

Gamigin, known as the Soulcounter, is a demon prince who oversees the Abyssal judgment of souls and the delicate balance between life and death. His obsession with calculating souls stems from his belief that the Abyss is the true keeper of fate, with each soul simply a cog in the endless machine of the multiverse. The souls that pass through his domain are weighed, judged, and ultimately consumed to feed the Abyss’s ever-growing power.

Gamigin perceives himself as the ultimate arbiter, a being who has mastered the laws of life, death, and decay. His presence in the multiverse is not merely about death—his obsession with collecting debts of souls extends beyond simple justice. He intends to accumulate greater power for the Abyss, believing this will allow him to reshape existence itself.

Gamigin commands legions of followers, most notably lich-like necromancers, who view him as a mentor in soul preservation. His influence spreads throughout the Material Plane, where dark cults and necromancers revere him, attempting to emulate his mastery over death and the afterlife.

Ultimate Goal: Gamigin’s goal is to elevate the Abyss to a higher plane of existence, where it becomes the central force of the cosmos. By acquiring countless souls, he intends to gather the strength needed to overthrow the other demon lords and ultimately claim dominion over all undeath, securing his position as the undisputed master of souls.

---

PERSONALITY AND MOTIVATION

Gamigin is calculating, precise, and relentlessly methodical in all his actions. He sees souls as tools to be manipulated, with little regard for morality. His obsession with maintaining a delicate balance between life and death drives him to meticulously track the fate of every soul. He acts with a cold, calculating demeanor, but beneath the veneer of logic lies a burning desire for ultimate power and control over all realms.

Gamigin seeks to expand the Abyss, growing stronger with each consumed soul. He is constantly working towards gathering knowledge and influence to achieve his final ascension. His rivalry with Orcus is one of pure strategy, as he aims to dominate the realm of undeath and dethrone the demon prince of the undead.

---

TREASURE AND ARTIFACTS

Brush of Fate: An artifact that allows Gamigin to mark souls for destruction, control their fates, and manipulate magical energies. The brush’s bristles are made from the hairs of ancient demons, and its power can be used to channel chaotic forces in battle.

Spirit Ledger: A legendary tome that holds the true names and fates of every soul entering the Abyss. It grants Gamigin unparalleled control over the flow of souls within his domain.

Gamigin (Samigina)

Designed By Aaron Loeb, Erik Mona, Chris Pramas, and Robert J. Schwalb

Originally from The Book of Fiends

Few cynical students of the occult are surprised upon learning of Gamigin, the demonic patron of the universal constants: death and taxes. When a chaotic evil creature dies, its soul manifests in the Abyss, where it must either quickly learn to protect itself or be devoured by ravenous demons. From the moment the soul arrives until its destruction, its activities and whereabouts are meticulously tracked by Gamigin, the calculating demon prince known as the Soulcounter.

Gamigin evaluates the worth of each soul against ancient, esoteric formulae. When he identifies an “imbalance,” he dispatches his skullduggers to collect the debt owed to the Abyss. These servitors capture the soul and transport it to Gamigin’s lair on the Jagged Tor of Final Reckoning, where it is cast into the Last Morass, a boiling pit of magical tar that utterly annihilates it. While Gamigin appears to derive satisfaction from these destructions, the true beneficiary is the Abyss itself, which grows stronger with each consumed soul. Some whisper that Gamigin is not a demon prince in full control of his domain but a mere servant of the Abyss’s will, more dominated than dominant.

The studious Gamigin wears the somber robes of a scholar and carries the Spirit Ledger, a massive tome recording the fate of every soul that enters the Abyss. His weapon of choice is an oversized brush, which he uses to inscribe calamitous symbols in the air when threatened. At his command, this brush can transform into a scythe. His head, shaped like that of a horse, is crowned by an intricate array of antlers, lending him a regal yet unsettling presence.

The Jagged Tor of Final Reckoning, Gamigin’s lair, is a colossal stone citadel perched atop a mile-high mesa of gnarled, mutant flesh. Below the mesa, poisonous clouds thick enough to harm even demons obscure the Abyssal landscape. The citadel’s vast hallways rise several stories and are lined with meticulously organized bookcases containing records of every soul in the Abyss. Gamigin guards these records jealously, as they provide the current location and status of every creature in the plane. Seventeen chambers within the citadel store treasure offered in exchange for his coveted knowledge. Although Gamigin cares little for wealth, he takes immense pride in its accumulation and seeks to see it grow.

On the Material Plane, Gamigin’s followers are primarily liches or spellcasters on the path to lichdom. These undead beings, whose souls are anchored between life and afterlife, are uniquely positioned to approach Gamigin as equals. They seek his expertise in protecting their souls from threats, a form of wisdom he is uniquely equipped to offer. Gamigin’s cult is notably more refined than the gruesome worship of Orcus, the demon prince of undeath, with whom he shares a bitter rivalry. Their enmity stems from the early days of demonic history, when they vied for control over undeath. Though Orcus emerged victorious, Gamigin remains watchful, ready to seize power should his rival falter.

Obedience

To deepen their understanding of death and undeath, thaumaturges devoted to Gamigin perform unsettling daily rituals. They use specially prepared pins, oils, and unguents to mortify a one-inch-square patch of their flesh, usually on a concealed part of the body. Over several days, the dead tissue begins to decay, becoming infested with maggots and parasites. During the ritual, the thaumaturge removes one of these maggots and places it into their eye socket, allowing it to squirm against the eyeball. This grotesque act is believed to provide insight into the realms beyond mortality. After a few minutes, the maggot dissolves into the caster’s flesh, replenishing their spells for the day.

Defensive Abilities

Death’s Balance (Su):

Gamigin keeps meticulous records of every soul that passes into the Abyss. He has the ability to negate any attack that would affect his person or his allies within 30 feet once per round, reflecting his control over the flow of souls. When an attack is directed at him, as a swift action, he may weigh its outcome and nullify the attack, turning it into an illusion of failure. This defense can be invoked once every 1d4 rounds.

Abyssal Consignment (Su):

As the keeper of soul’s fate, Gamigin can consign a creature’s soul to the Abyss upon death, preventing resurrection. Upon killing a creature, he may use a swift action to bind its soul to the Abyss for a century, after which the soul is erased and lost to time. This also prevents the use of Resurrection, Reincarnation, or similar effects on the soul for 100 years. Any creature with an unnatural or undead nature (such as a lich) is particularly vulnerable to this power.

Regeneration (Ex):

Gamigin regenerates 15 hit points per round. If reduced to 0 hit points, he automatically retreats to the Abyss, reforming within 1d10 days unless permanently destroyed (via a Wish spell or equivalent). However, while in the Abyss, he may still oversee his plots and plans, continuing his control over the realm of souls.

Form of the Soulcounter (Su):

Gamigin can temporarily transform his form into that of the Soulcounter, a dark and towering avatar. His appearance changes as his horse skull is crowned with antlers, and his robes flow like tattered flesh. His slams increase to 2d8+18 damage, and each attack deals an additional 2d6 unholy damage. He gains a +4 deflection bonus to AC and becomes immune to mind-affecting spells. This form lasts for 10 rounds and can be used once every 1d4 rounds.

Special Abilities

Soul Siphon (Su):
As an action, Gamigin may focus on a creature’s soul within 60 feet, draining its vitality and adding it to his own life force. The target must make a DC 34 Will save or suffer 2d6 Constitution damage. For every point of Constitution damage dealt, Gamigin gains an equal number of temporary hit points that last for 1 hour. He can use this ability up to 3 times per day.

---

Combat Tactics

Gamigin is a master tactician, calculating every move with a cold, meticulous precision. His Soul Siphon lets him recover while simultaneously weakening enemies, making him an excellent opponent for drawn-out conflicts. He relies heavily on Dominate Person and Fear to weaken or control foes, while his Abyssal Consignment ensures that any significant adversaries cannot be brought back once slain.

When the battlefield is overwhelmed with too many enemies, he will cast Meteor Swarm or Horrid Wilting to deal massive damage across wide areas, targeting anyone who dares defy his control. For closer combat, he uses Form of the Soulcounter to dramatically increase his survivability and to press his advantage. His Death’s Balance ability prevents most critical strikes, giving him the upper hand against even the strongest attackers.

---

Legendary Actions

Gamigin can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time, and only at the end of another creature’s turn. Gamigin regains spent legendary actions at the start of his turn.

• Cast a Spell (Costs 2 Actions): Gamigin casts any 1st to 5th-level spell he knows (as a spell-like ability).
• Soul Rip (Costs 1 Action): Gamigin makes a single slam attack. If this attack hits, the target must make a DC 34 Will save or have their soul siphoned, taking 2d6 points of Constitution damage.
• Flesh of the Abyss (Costs 3 Actions): Gamigin reshapes the ground around him, causing 20-foot radius area to become covered in sharp, thorny tendrils that deal 4d6 piercing damage to all creatures within.

---

Environment:

Gamigin resides in his dark and oppressive citadel, The Jagged Tor of Final Reckoning, a massive fortress located atop a mile-high mesa of tangled, twisted flesh that stands in stark contrast to the otherwise barren and hostile landscape. The landscape around him is littered with broken stone, the remains of failed attempts to scale the tor. The air is thick with the smell of decay and corruption, and no living thing dare approach. Toxic clouds of ash and smoke perpetually obscure the sky.

Inside the citadel, towering spires made of fleshy materials line the halls. Gigantic tomes of soul records stretch across vast, cathedral-like rooms, containing details of every creature’s fate in the Abyss, meticulously cataloged by Gamigin himself. The walls are adorned with swirling, haunting sigils of dark power. A room dedicated to wealth and treasure houses a vast array of arcane artifacts, valuable tomes, and bindings of lost souls.

---

Lore

Gamigin, the Soulcounter, is a demon prince whose obsession lies in the meticulous tracking and management of souls in the Abyss. His goal is not to destroy or conquer for the sake of chaos, but to maintain balance — the kind of balance that can only come from controlling every life and death. Each soul, every fate, must be weighed and dealt with in accordance to the strict codes of the Abyss’s inner laws.

Gamigin is a rival to Orcus, and their competition over the dominion of death and undeath has existed for millennia. Despite losing the battle for control over undeath in the Material Plane to Orcus, Gamigin’s role is still one of power and manipulation, commanding a vast knowledge of the underworld. He is a constant observer, seeing the invisible strings that tie life to death, controlling when and where they snap.

---

Treasure

Gamigin’s wealth is far more than material; it is symbolic. His prized possession is the Spirit Ledger, a book containing the recorded fate of every soul in the Abyss. This tome is said to hold the key to manipulating souls and bending reality itself. His treasures include cursed artifacts, arcane relics, and binding sigils, each a part of his greater goal to maintain the flow of the multiverse’s natural laws. Gamigin’s obsession with these treasures, however, is not for personal gain but as a means of furthering his control over fate and souls.
