Where Warden of the Firebox waits
Warden of the Firebox holds the gates at depths 57,800, 58,400, 59,000, 59,600, 60,200 in The Furnace Roots, sharing the zone's 100-depth gate rhythm with The Stoker of Hell and The Boilerlord and The Great Bellows and The Slagfather and The Gaugewright.
What Warden of the Firebox is
Warden of the Firebox is a Knight: it swings a sword, and the body asks for fast builds beware: the more you swing, the more it hits back — and it wards off blows from afar. 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.
Warden of the Firebox 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 DISCIPLINE- every body that steps within 4.5 tiles gains a shell of 20% of its health
OF ENDURANCE- gains an Endurance charge every second while hit recently: +15% physical reduction and +15% to the elements each, up to 3
FIREPROOF- +75% fire resistance (capped at 75%)
OF POWER- gains a Power charge on every hit it lands: +200% critical chance each, up to 3
OF HINDERING- you move 30% slower within 4.5 tiles of it
OVERWHELMING- ignores 30 points of your armor
WITHERING- every blow leaves damage over time on you: 15% of the blow each second for 4 s
EVASIVE- +22% chance to dodge your hits
ENRAGED- builds 2 Rage with every blow it lands, up to 50; each point is 1% more damage
SUNDERING- every blow cuts your armor by 30% for 4 s
STORMSHIELDED- +75% lightning resistance (capped at 75%)
ETHEREAL- takes 60% less from HITS, and double from damage over time
BURNING- +35% ignite chance; a quarter of its physical damage becomes fire
VENOMOUS- +35% chance to poison you
PIERCING- penetrates 25% of your resistances
LUCKY- 15% of its blows land twice over
RETALIATING- strikes back at once when one blow takes more than 8% of its health and you stand within 2.5 tiles
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 Warden of the Firebox leads with 45,331,824,239 health, against 22,967,300,902 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.
