Where Ephialtes the Chained waits
Ephialtes the Chained holds the gates at depths 32,100, 32,700, 33,300, 33,900, 34,500 in The Well of Giants, sharing the zone's 100-depth gate rhythm with Nimrod the Babbler and Antaeus Unbound and The Foundation Stone and Warden of the Well and The Marrow Colossus.
What Ephialtes the Chained is
Ephialtes the Chained 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.
Ephialtes the Chained 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 ENDURANCE- gains an Endurance charge every second while hit recently: +15% physical reduction and +15% to the elements each, up to 3
OF DISCIPLINE- every body that steps within 4.5 tiles gains a shell of 20% of its health
STORMSHIELDED- +75% lightning resistance (capped at 75%)
BARRIERED- Opens behind a barrier worth 25% of its health
CORRUPTING- a third of its damage is chaos
SHOCKING- +35% shock chance; a quarter of its physical damage becomes lightning
WITHERING- every blow leaves damage over time on you: 15% of the blow each second for 4 s
RETALIATING- strikes back at once when one blow takes more than 8% of its health and you stand within 2.5 tiles
OF CHILLING DEATH- leaves a pool of frost where it falls
OVERWHELMING- ignores 30 points of your armor
ROTPROOF- +75% chaos resistance (capped at 75%)
PIERCING- penetrates 25% of your resistances
VAMPIRIC- heals 1.5% of its maximum health with every blow it lands
ENRAGED- builds 2 Rage with every blow it lands, up to 50; each point is 1% more damage
CHILLING- Turns 30% of its physical damage into cold
MANGLING- +35% chance to cause bleeding
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 Ephialtes the Chained leads with 13,389,258,307 health, against 11,900,793,550 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.
