Where The Under-Delver waits
The Under-Delver holds the gates at depths 24,100, 24,700, 25,300, 25,900, 26,500 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 Brittle Colossus.
What The Under-Delver is
The Under-Delver 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 Under-Delver 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
CHILLING- Turns 30% of its physical damage into cold
ETHEREAL- takes 60% less from HITS, and double from damage over time
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
SUNDERING- every blow cuts your armor by 30% for 4 s
SHOCKING- +35% shock chance; a quarter of its physical damage becomes lightning
OF HINDERING- you move 30% slower within 4.5 tiles of it
OF CHILLING DEATH- leaves a pool of frost where it falls
ARMORED- Armour ×1.9, at the cost of 5% of its health
OF THE EXECUTIONER- you recover half as much within 4.5 tiles of it
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
OF HASTE- the pack within 4.5 tiles moves and swings 30% faster
OF FRENZY- gains a Frenzy charge on every hit it lands: 4% more damage, +15% attack speed and +5% movement each, up to 3
OF FLAMING DEATH- leaves a pool of fire where it falls
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 Under-Delver leads with 7,384,552,879 health, against 5,907,133,238 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.
