Where The Mould-King waits
The Mould-King holds the gates at depths 74,800, 75,400, 76,000, 76,600, 77,200 in The Unmade, sharing the zone's 100-depth gate rhythm with The Unmaker and The First Draft and The Armature and The Rough Hand and The Cornerstone.
What The Mould-King is
The Mould-King is a Brute: it swings a mace, and the body asks for the guard shell, armor against a heavy blow, stalling — it wards off blows from afar and hooks you in. As a boss it wears the type's defences at 35%, carries no status of its own, and enrages below half health: it hits harder and moves faster.
The Mould-King by the numbers
The card at each gate — health, damage per swing, armour and the modifiers it rolls — straight from the game's spawn table. On the floor the boss leads with 60% of the card's health and 60% of its damage, before the road's own pressure.
What those modifiers do
OF PRECISION- the pack within 4.5 tiles crits 15% more often
VENOMOUS- +35% chance to poison you
BURNING- +35% ignite chance; a quarter of its physical damage becomes fire
SUNDERING- every blow cuts your armor by 30% for 4 s
PIERCING- penetrates 25% of your resistances
OF SHOCKING DEATH- leaves a pool of lightning where it falls
WITHERING- every blow leaves damage over time on you: 15% of the blow each second for 4 s
BARRIERED- Opens behind a barrier worth 25% of its health
ENRAGED- builds 2 Rage with every blow it lands, up to 50; each point is 1% more damage
EVASIVE- +22% chance to dodge your hits
FROSTBOUND- +75% cold resistance (capped at 75%)
DEADLY- +20% critical strike chance
OF CHILLING DEATH- leaves a pool of frost where it falls
OF THE EXECUTIONER- you recover half as much within 4.5 tiles of it
OF FLAMING DEATH- leaves a pool of fire where it falls
Modifiers are rolled per depth and are the same for every player. Bosses always carry at least 3 and never a pace modifier (SWIFT, BRUTE), so a boss's swing rhythm is its own; of the seals only the walls — BLOODLESS, INERT, ASHEN, ETHEREAL, DENSE — ride a boss. The full list is in Enemy modifiers.
At its first gate The Mould-King leads with 77,330,140,330 health, against 61,862,399,611 for the leader one floor above, and swings every 1.25s.
What a gate floor is
A gate is a floor like any other, with the boss leading its last pack. Nothing below it opens until the floor is cleared. A lost floor costs nothing; you can fight it again. How a floor is fought is under Combat.
