Where The Gnomon waits
The Gnomon holds the gates at depths 83,300, 83,900, 84,500, 85,100, 85,700 in The Black Sun, sharing the zone's 100-depth gate rhythm with Herald of the Black Dawn and The Eclipse Tyrant and The Cinder Sovereign and The Black Idol and The Devourer of Noon.
What The Gnomon is
The Gnomon is a Wight: it swings an axe, and the body asks for burst damage — it heals as it fights. 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 Gnomon 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
SHOCKING- +35% shock chance; a quarter of its physical damage becomes lightning
OF DAMAGING- the pack within 4.5 tiles hits 25% harder
EVASIVE- +22% chance to dodge your hits
CORRUPTING- a third of its damage is chaos
RETALIATING- strikes back at once when one blow takes more than 8% of its health and you stand within 2.5 tiles
REGENERATING- Heals 1% of its maximum health every second
OVERWHELMING- ignores 30 points of your armor
OF HASTE- the pack within 4.5 tiles moves and swings 30% faster
THICK-SKINNED- Overwhelm and armor you ignore count at half
LUCKY- 15% of its blows land twice over
WITHERING- every blow leaves damage over time on you: 15% of the blow each second for 4 s
OF FRENZY- gains a Frenzy charge on every hit it lands: 4% more damage, +15% attack speed and +5% movement each, up to 3
FIREPROOF- +75% fire resistance (capped at 75%)
DEADLY- +20% critical strike chance
VAMPIRIC- heals 1.5% of its maximum health with every blow it lands
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 Gnomon leads with 96,634,467,218 health, against 42,947,584,698 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.
