Where The Foundation Stone waits
The Foundation Stone holds the gates at depths 32,400, 33,000, 33,600, 34,200, 34,800 in The Well of Giants, sharing the zone's 100-depth gate rhythm with Ephialtes the Chained and Nimrod the Babbler and Antaeus Unbound and Warden of the Well and The Marrow Colossus.
What The Foundation Stone is
The Foundation Stone 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 Foundation Stone 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
BARRIERED- Opens behind a barrier worth 25% of its health
MANGLING- +35% chance to cause bleeding
OF CHILLING DEATH- leaves a pool of frost where it falls
OF SHOCKING DEATH- leaves a pool of lightning where it falls
OF PRECISION- the pack within 4.5 tiles crits 15% more often
SHOCKING- +35% shock chance; a quarter of its physical damage becomes lightning
DRAINING- you recover half as much: leech, regen, recoup
VENOMOUS- +35% chance to poison you
VAMPIRIC- heals 1.5% of its maximum health with every blow it lands
PIERCING- penetrates 25% of your resistances
DENSE- takes 60% less from damage over TIME, and double from hits
OVERWHELMING- ignores 30 points of your armor
DEADLY- +20% critical strike chance
RETALIATING- strikes back at once when one blow takes more than 8% of its health and you stand within 2.5 tiles
BURNING- +35% ignite chance; a quarter of its physical damage becomes fire
ETHEREAL- takes 60% less from HITS, and double from damage over time
EXPOSING- every blow cuts your resistances by 15 for 4 s
THICK-SKINNED- Overwhelm and armor you ignore count at half
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 Foundation Stone leads with 13,650,233,266 health, against 6,066,381,788 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.
