Where The Orrery Engine waits
The Orrery Engine holds the gates at depths 66,400, 67,000, 67,600, 68,200, 68,800 in The Starless Deep, sharing the zone's 100-depth gate rhythm with The Unlit One and The Sightless Crown and The Last Meridian and The Star-Reader and The Undawn.
What The Orrery Engine is
The Orrery Engine 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 Orrery Engine 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
ROTPROOF- +75% chaos resistance (capped at 75%)
OF ENDURANCE- gains an Endurance charge every second while hit recently: +15% physical reduction and +15% to the elements each, up to 3
CHILLING- Turns 30% of its physical damage into cold
OF FLAMING DEATH- leaves a pool of fire where it falls
OF SHOCKING DEATH- leaves a pool of lightning where it falls
DENSE- takes 60% less from damage over TIME, and double from hits
OF DISCIPLINE- every body that steps within 4.5 tiles gains a shell of 20% of its health
OF PRECISION- the pack within 4.5 tiles crits 15% more often
OF HASTE- the pack within 4.5 tiles moves and swings 30% faster
EVASIVE- +22% chance to dodge your hits
OF HINDERING- you move 30% slower within 4.5 tiles of it
OVERWHELMING- ignores 30 points of your armor
OF THE EXECUTIONER- you recover half as much within 4.5 tiles of it
RETALIATING- strikes back at once when one blow takes more than 8% of its health and you stand within 2.5 tiles
THICK-SKINNED- Overwhelm and armor you ignore count at half
VAMPIRIC- heals 1.5% of its maximum health with every blow it lands
FIREPROOF- +75% fire resistance (capped at 75%)
ENRAGED- builds 2 Rage with every blow it lands, up to 50; each point is 1% more damage
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 Orrery Engine leads with 60,423,305,911 health, against 80,561,894,658 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.
