Where The Slagfather waits

The Slagfather holds the gates at depths 58,000, 58,600, 59,200, 59,800, 60,400 in The Furnace Roots, sharing the zone's 100-depth gate rhythm with The Stoker of Hell and The Boilerlord and Warden of the Firebox and The Great Bellows and The Gaugewright.

What The Slagfather is

The Slagfather is a Golem: it swings a mace, and the body asks for Overwhelm, the elements instead of physical — and a second wind: a big one breaks into two. 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 Slagfather 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.

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 Slagfather leads with 45,657,446,606 health, against 20,291,473,556 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.
