Unmade King

Major spoilers

This page contains significant lore spoilers for the Sunless Throne and the game’s overarching plot. Read at your own discretion.

The Unmade King is the endgame boss of the Sunless Throne and the most challenging encounter in Yomi no Sho as of patch 2.4. The King is a unique enemy with multiple phases, complex mechanics, and lore implications that extend throughout the game’s plot. Defeating the King weekly is the primary endgame activity for high-Ascension accounts, and the King’s drop table includes several of the rarest items in the game.

This page covers the King’s stats, its mechanics in each phase, the recommended strategy, and its lore. The strategy section assumes the reader has a fully-Ascended party; the King is not intended to be challenged by undergeared accounts.

Stats

The Unmade King’s stats:

Stat	Value	Notes
HP	4,500,000	The highest in the game by an order of magnitude.
Attack	850	High; will one-shot most Shades without mitigation.
Defence	350	High; reduces incoming damage significantly.
Speed	80	Slow; the player’s Shades will usually act first.
Affinity	Void	Strong vs Earth, weak vs Wood.
Resistance	50% to Void, 30% to all others	Extremely resistant.

The King’s stats are calibrated for a party of three Ascension-5 Shades with tier-3 gear. A party below this threshold will struggle to out-damage the King’s HP regeneration, which is the encounter’s primary enrage mechanic.

Phase 1: The Court of the Unmade

The fight begins with the King alone on the field, in the centre of a vast, empty void. The King has two abilities in phase 1:

Decree of Silence — a single-target attack that deals 1.5x Attack damage and silences the target for 5 seconds. The King uses Decree of Silence on a 12-second cooldown, prioritising the Shade with the highest current AP.
Summon Unmade — a channelled ability that summons 2 Unmade Thralls (weaker versions of the Wandering Hollow, scaled to the King’s tier). The King uses Summon Unmade on a 30-second cooldown.

Phase 1 lasts until the King reaches 75% HP. The strategy is to focus damage on the King while ignoring the Thralls, which are too weak to threaten a tier-3 party but too numerous to ignore indefinitely. The Thralls can be cleared by AoE skills if they become problematic.

The Decree of Silence is the primary threat in phase 1. The silence prevents the silenced Shade from using skills, which can disrupt the party’s rotation. The counter is to bring a Shade with a cleanse skill (most support Shades have one), or to plan the rotation around the silence — the silenced Shade can still use basic attacks, which means the rotation’s basic-attack phases should be aligned with the silence cooldown.

Phase 2: The Empty Throne

At 75% HP, the King transitions to phase 2. The transition is instantaneous and includes a brief invulnerability window. In phase 2, the King gains two new abilities:

Decree of Dissolution — a party-wide attack that deals 1.0x Attack damage and applies a 5% Diminution stack to all Shades. The Diminution stacks persist for the rest of the fight. The King uses Decree of Dissolution on a 45-second cooldown.
Consume Unmade — a channelled ability that consumes all Unmade Thralls on the field, healing the King for 5% of its max HP per Thrall consumed. The King uses Consume Unmade on a 60-second cooldown, but only if Thralls are present.

Phase 2 lasts until the King reaches 50% HP. The strategy is to manage the Thralls carefully — the King’s Consume Unmade can heal it for up to 10% of its max HP per use, which can undo several minutes of damage. The counter is to clear the Thralls before the King can consume them, which requires the party to split damage between the King and the Thralls.

The Decree of Dissolution is the primary threat in phase 2. The Diminution stacks persist for the rest of the fight, which means the party’s effective HP and damage decrease over time. The counter is to bring a Shade with a Diminution cleanse skill (rare; only two Shades in the game have one — the Scribe, who is unobtainable, and Yomotsu-Shikome at Ascension 5 with the Withering Set). Most accounts do not have access to a Diminution cleanse, which makes phase 2 a race against the Diminution stacks.

Phase 3: The King Alone

At 50% HP, the King transitions to phase 3. The transition is instantaneous and includes a 5-second invulnerability window, during which the King casts Final Decree — a party-wide attack that deals 2.0x Attack damage and applies a 10% Diminution stack to all Shades. This attack is unavoidable and is the primary gear check of the fight; a party without sufficient HP will be wiped.

In phase 3, the King loses the Summon Unmade and Consume Unmade abilities, but gains two new abilities:

Decree of Unmaking — a single-target attack that deals 3.0x Attack damage and applies a 20% Diminution stack. The King uses Decree of Unmaking on a 20-second cooldown, prioritising the Shade with the lowest current HP.
Aura of Dissolution — a passive aura that deals 0.5x Attack damage to all Shades every tick. This damage is not reduced by Defence and cannot be mitigated by any means other than HP.

Phase 3 lasts until the King reaches 0 HP. The strategy is a pure damage race — the King’s HP regeneration (1% per tick, applied at the end of each tick) means the party must out-damage the regeneration while surviving the Aura of Dissolution and the Decree of Unmaking. The Decree of Unmaking will one-shot any Shade below 30% HP, which means the party must keep all Shades above 30% HP at all times.

Recommended strategy

The community consensus strategy for the Unmade King is:

Party composition: Kagaribi (Heartfire Set, Ascension 5), Tengu (Skyfather Set, Ascension 5), Yomotsu-Shikome (Withering Set, Ascension 5). This party provides the branding, grounding, and decaying effects, which multiply to produce a 4.5x damage multiplier on the King.
Phase 1: Focus damage on the King. Kagaribi applies branding, Tengu applies grounding, Yomotsu-Shikome applies decaying. The Thralls are ignored unless they reach 4 or more, at which point Tengu uses Tempest to clear them.
Phase 2: Same as phase 1, but with careful Thrall management. The party must clear Thralls before the King’s Consume Unmade cooldown expires, which requires Tengu to save Tempest for Thrall clears rather than single-target damage.
Phase 3: Pure damage race. All Shades use their ultimates on cooldown, with Kagaribi’s Watchfire Eternal as the primary damage source. Yomotsu-Shikome uses Embrace of the Hag to apply the decaying effect, which is the only way to out-damage the King’s regeneration.

The expected clear time with this strategy is 4–6 minutes, depending on gear quality and RNG. The King’s drop table includes the rarest items in the game, which makes the weekly clear the primary endgame activity for high-Ascension accounts.

Lore

The Unmade King is the lore-explanation for the Sunless Throne’s sole inhabitant. In the metaphysics of Yomi, the King is the most-coherent of the Unmade — a soul that was so thoroughly forgotten by the living world that it should have dissolved entirely, but which retained enough coherence to become a threat to Yomi itself.

The King’s identity is the subject of significant lore speculation. The game’s plot establishes that the King was once a mortal — a ruler of some kind, given the “King” title — but does not specify which mortal. The community has proposed several candidates, ranging from historical figures to characters referenced elsewhere in the lore. The most-discussed theory is that the King is the original Scribe — the one who was Unmade in the Loss — but this theory has not been confirmed and is contradicted by several lore fragments.

The King’s Decree abilities are lore-justified as remnants of its mortal authority. In life, the King was a ruler whose decrees shaped the world; in death, the King’s decrees still shape Yomi, but in a diminished and corrupted form. The Decree of Silence mutes, the Decree of Dissolution unmakes, and the Decree of Unmaking erases. The progression reflects the King’s gradual descent from coherent ruler to Unmade threat.

The King’s relationship with the Scribe is the source of significant lore tension. The Scribe is visibly uncomfortable when discussing the King, and several late-game dialogue options suggest that the Scribe knows more about the King’s identity than he is willing to share. The community expects this to be a major plot point in future content updates.

Trivia

The Unmade King is the only enemy in the game with a unique boss arena. The arena is a vast, empty void with no floor, no ceiling, and no walls — only the King and the player’s Shades, suspended in absolute darkness.
The King is the only enemy in the game with a unique death animation. Instead of dissolving, the King’s model slowly collapses into a small, glowing point of light, which then fades. The community has interpreted this as the King’s soul finally achieving the dissolution it had been denied.
The King is the only enemy in the game with a unique drop table. The drops include the King’s Decree, a unique item that grants the player a single-use copy of one of the King’s Decree abilities. The item is consumed on use and is one of the most valuable items in the game.
