Where The Brittle Colossus waits
The Brittle Colossus holds the gates at depths 24,000, 24,600, 25,200, 25,800, 26,400 in The Frozen Deep, sharing the zone's 100-depth gate rhythm with The Sleeper in the Ice and The Keystone Warden and The Drowned Architect and The Tolling Warden and The Under-Delver.
What The Brittle Colossus is
The Brittle Colossus 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 Brittle Colossus 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
STORMSHIELDED- +75% lightning resistance (capped at 75%)
BURNING- +35% ignite chance; a quarter of its physical damage becomes fire
SHOCKING- +35% shock chance; a quarter of its physical damage becomes lightning
OF SHOCKING DEATH- leaves a pool of lightning where it falls
OF POWER- gains a Power charge on every hit it lands: +200% critical chance each, up to 3
MANGLING- +35% chance to cause bleeding
THICK-SKINNED- Overwhelm and armor you ignore count at half
OF CHILLING DEATH- leaves a pool of frost where it falls
OF PRECISION- the pack within 4.5 tiles crits 15% more often
OF THE EXECUTIONER- you recover half as much within 4.5 tiles of it
VAMPIRIC- heals 1.5% of its maximum health with every blow it lands
LUCKY- 15% of its blows land twice over
ROTPROOF- +75% chaos resistance (capped at 75%)
EVASIVE- +22% chance to dodge your hits
CHILLING- Turns 30% of its physical damage into cold
RETALIATING- strikes back at once when one blow takes more than 8% of its health and you stand within 2.5 tiles
DRAINING- you recover half as much: leech, regen, recoup
VENOMOUS- +35% chance to poison you
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 Brittle Colossus leads with 7,321,060,102 health, against 9,760,568,809 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.
