Where The Boiling Tyrant waits
The Boiling Tyrant holds the gates at depths 17,700, 18,000, 18,300, 18,600, 18,900, 19,200 and onward in The Phlegethon, sharing the zone's 100-depth gate rhythm with The Crimson Warden and The Flayed Colossus.
What The Boiling Tyrant is
The Boiling Tyrant 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 Boiling Tyrant 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
WITHERING- every blow leaves damage over time on you: 15% of the blow each second for 4 s
OF CHILLING DEATH- leaves a pool of frost where it falls
OF FLAMING DEATH- leaves a pool of fire where it falls
FROSTBOUND- +75% cold resistance (capped at 75%)
VENOMOUS- +35% chance to poison you
ARMORED- Armour ×1.9, at the cost of 5% of its health
EVASIVE- +22% chance to dodge your hits
OF PRECISION- the pack within 4.5 tiles crits 15% more often
OF DISCIPLINE- every body that steps within 4.5 tiles gains a shell of 20% of its health
CHILLING- Turns 30% of its physical damage into cold
CORRUPTING- a third of its damage is chaos
ENRAGED- builds 2 Rage with every blow it lands, up to 50; each point is 1% more damage
OF SHOCKING DEATH- leaves a pool of lightning where it falls
OF HINDERING- you move 30% slower within 4.5 tiles of it
EXPOSING- every blow cuts your resistances by 15 for 4 s
OF POWER- gains a Power charge on every hit it lands: +200% critical chance each, up to 3
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 Boiling Tyrant leads with 3,888,933,571 health, against 2,073,854,350 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.
