Where The Last Turnkey waits
The Last Turnkey holds the gates at depths 40,900, 41,500, 42,100, 42,700, 43,300 in The First Prison, sharing the zone's 100-depth gate rhythm with The Sealed One and The First Warden and The Doorless Gate and The Sigil-Speaker and The Warden's Hunger.
What The Last Turnkey is
The Last Turnkey is a Wight: it swings an axe, and the body asks for burst damage — it heals as it fights. 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 Last Turnkey 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 FRENZY- gains a Frenzy charge on every hit it lands: 4% more damage, +15% attack speed and +5% movement each, up to 3
FROSTBOUND- +75% cold resistance (capped at 75%)
VAMPIRIC- heals 1.5% of its maximum health with every blow it lands
OF FLAMING DEATH- leaves a pool of fire where it falls
OVERWHELMING- ignores 30 points of your armor
PIERCING- penetrates 25% of your resistances
OF POWER- gains a Power charge on every hit it lands: +200% critical chance each, up to 3
MANGLING- +35% chance to cause bleeding
BURNING- +35% ignite chance; a quarter of its physical damage becomes fire
STORMSHIELDED- +75% lightning resistance (capped at 75%)
ENRAGED- builds 2 Rage with every blow it lands, up to 50; each point is 1% more damage
SHOCKING- +35% shock chance; a quarter of its physical damage becomes lightning
OF ENDURANCE- gains an Endurance charge every second while hit recently: +15% physical reduction and +15% to the elements each, up to 3
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 Last Turnkey leads with 22,132,676,528 health, against 21,639,741,968 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.
