Behavior

The Factory Control Core is found at the end of the Kogbold Steamworks in a massive, square room that initially has no other objects within save for a border of hazardous Steam Vents that deal a higher 80 damage per tick compared to most of those found in the dungeon. It initially wanders around aimlessly, but will activate when attacked enough, moving to the center of the room and initiating combat.
“Hostile presence detected…”

Phase 1

Taunt: “…Initiate defense protocol: Windup”
The Factory Control Core fills the outer portion of the arena with damaging Steam Vents (leaving a much smaller platform of safe tiles), and divides the platform into quadrants with four conveyor belts in a plus shape that push players outward. Four turrets spawn at the corners of the room and begin firing slow red orbs in various spread patterns to restrict player movement, and arrays of crushers will periodically spawn in various patterns, slamming down to deal AoE damage after a telegraph. The Core itself will be stationary, firing aimed spreads of stagnating blue arrowheads at the nearest player while firing solid “blocks” of red arrowheads in two directions, rotating the orientation of the attack 45 degrees clockwise each time.

At the start of the phase, four Shield Generators will spawn in the corners of the arena next to the turrets; these will be invulnerable for a few seconds upon spawning and be marked on the minimap by blue dots. Destroying all four Generators is needed to make the boss start taking damage. Once the phase ends, all turrets stop firing and all hazards disappear outside of the outermost ring of Steam Vents, which now seals off the entrance to the room.

Phase 2

Taunt: “Threat level increased”
At 90% HP, the Factory Control Core chooses a random “defense” attack out of 3 possible ones. Each attack is announced in advance by the Core in the chat, and often drastically changes the structure of the arena with new hazards and Steam Vents surrounding the new arena. During each phase, players must find and destroy the four Shield Generators to render the Core vulnerable.

The Core will switch to a new attack when brought to 75% HP. When an attack ends, there is a noticeable delay to allow the arena to return to its default state and to let lingering shots clear out.
“Recalibrating…”

Push Apart

The Core transforms the arena into a rectangle of conveyor belts that push players away from the central axis. A line of turrets along the central axis will start firing walls of shots parallel to the conveyor belts’ directions; these span the length of the rectangle but have periodic gaps to dodge through. Two lines of turrets at the short ends of the rectangle will periodically fire single slow sawblade projectiles perpendicular to the conveyor belts’ directions. The Core itself does not move or attack during this phase.

The Shield Generators are evenly spaced along the central axis.

Scatter

The Core transforms the arena into a cross-shaped platform, with a smaller cross of Steam Vents in the center to limit movement and periodic triple crushers that slam down at the ends of the cross. A turret in the middle starts firing an oscillating barrage of slow blue arrowheads in all directions, while four turrets in the outermost corners of the room fire spreads of slow green arrowheads towards the center of the room. The Core itself will circle clockwise around the center turret, occasionally firing flame waves in four directions.

Two of the Shield Generators will be on opposite ends of the platform, while the other two will be right next to the center turret.

Semi-Spiral

The Core slightly shrinks the arena. A ring of invincible Factory Maintenance Cores rotate back and forth around the arena, firing silver arrowheads towards the center of the arena and releasing simultaneous rings of slow red waves whenever their rotation changes direction. The Core itself will remain stationary and fire a spiraling pattern of blue orbs, changing the spiral direction with each attack.

The Shield Generators are found at the corners of the platform.

Phase 3

Taunt: “Hostile vitals positive…deploying Enforcer Core”
At 60% HP, the Factory Control Core summons mechanical limbs and attaches them to itself to transform into a humanoid form, now called the Factory Enforcer Core. It follows a similar behavior to before, but now uses a new set of “enforcer” protocols where it takes on a more active role. The Core will choose one attack right after the phase begins and a new attack at 45% HP.

Minefield

The Core transforms the arena into a clover shaped platform. A central turret will fire rings of slow mines to create the namesake minefield of shots, and the corner turrets will fire pairs of flame shots aimed at the nearest player. The Core itself will chase players while firing four-way Quieting yellow arrowheads and launching aimed “arrows” of Quieting drills; it will periodically stop moving, become Armored, charge up power, and fire a barrage of slower yellow arrowheads in four directions.

The Shield Generators are at the corners of the arena, next to each of the corner turrets.

Sawblade

The Core transforms the arena into a square with two concentric rings of conveyor belts that travel in opposite directions. Turrets surrounding the platform will periodically fire walls of shots with evenly spaced gaps to dodge through, alternating between horizontal and vertical walls. The Core itself will be chasing players while firing spreads of wavy sawblades; it will periodically stop moving, become Armored, charge up power, and fire a spiraling barrage of larger sawblades.

Two Shield Generators are located at the corners of the outer conveyor belt ring, while two are located at the corners of the inner ring.

Crush Them

The arena remains unchanged in shape. Rings of crushers begin intermittently striking the platform; each ring starts by slamming down on the perimeter of the arena, with the ring shrinking more every time they slam down until they converge on the center. After two rings have fully converged, the crushers will instead slam down on the center and corners of the platform before reapeating. The Core itself will be chasing players while firing converging bursts of red shots, V-shaped bursts of more red shots to trap players, and spreads of blue arrowheads behind itself; it will periodically move to the center of the platform, become Armored, charge up power, and fire a spiral of blue arrowheads and rings of turning red waves. When the Core is in the center, the crushers will adopt a new pattern with crusher rings expanding outwards from the center of the room.

The Shield Generators are located at the corners of the platform.

Phase 4

Taunt: “Threat level: Unprecedented”
“All systems, full power…”
At 30% HP, the Factory Enforcer Core explodes with energy, melting and reforming its body into a draconic new form: Ferrus, Kogbold Deity. Ferrus still uses similar behavior to before, but now uses its most powerful “extermination” attacks. Like before, Ferrus will choose one attack at the start of the phase and a new attack at 15% HP.

Draconic Fury

Ferrus leaves the arena the way it is. Factory Maintenance Cores spawn and circle around the arena, firing turning brown waves perpendicular to their flight, while a turret in the center of the platform fires spirals of fireballs. Ferrus itself will be rotating counterclockwise around the arena while occasionally changing its orbit distance, firing radial bursts of fire shots.

The Shield Generators are located at the four cardinal points of the platform.

Rip and Tear

Ferrus shrinks the arena platform to only the square in the center. Factory Maintenance Cores circle around the platform, firing lines of red waves towards the center of the room, while a turret in the center fires a 2-way spiral of blue orbs. Ferrus itself will chase players with a 3-shot spread of silver arrows and periodic rings of silver arrowheads.

Unlike before, 6 Shield Generators will spawn around the perimeter of the platform.

Energy Storm

Ferrus slightly shrinks the arena platform and inflicts all players with Slowed for the duration of the phase. A line of turrets at the top of the arena fires a massive storm of slow blue bullets down the length of the arena, while two Factory Maintenance Cores oscillate up and down along the sides of the arena. Ferrus itself will be idly patrolling back and forth at the top side of the arena; every once in a while, it will stop in place alongside the two Maintenance Cores as all three of them charge up and simultaneously fire devastating laser beams straight ahead of themselves, telegraphed by lines of red crosshairs.

Unlike before, 6 Shield Generators will spawn; two at the top and bottom of the arena, one on the left side, and one on the right side.

Death Explosion

“Power limit reached…core overloaded…”
At 0.1% HP, all hazards in the room (except for the outer ring of Steam Vents) disappear. Ferrus retreats to the center of the room before its body explodes after a delay, leaving behind its molten core which bursts into electricity and releases rapid rings of flame shots while flailing erratically. After this final attack ends, the core explodes and is defeated for good, leaving behind any loot.

Advanced Steamworks

In the Advanced Kogbold Steamworks, instead of going through its usual death explosion, Ferrus will go invulnerable and launch a final desperation attack. Players will be inflicted with Sick, Silenced, Drought, and Exposed for the duration of the phase, which lasts for roughly 60 seconds and gets progressively harder over the duration.

• At the start of the phase, Ferrus will unleash a radial barrage of blue arrowheads as a chaotic barrage of Crushers periodically slams down on the entire arena.
• After ~15 seconds, the Crushers vanish and Ferrus’ arrowheads turn orange and more damaging. Ferrus transforms the arena into hazardous Steam Vents, with 8 safe spots made of conveyors that push players in one direction each; there will be a delay before Ferrus, the Steam Vents, and Conveyors activate to give players room to reposition. Once Ferrus resumes attacking, Crushers will periodically strike the center of each conveyor patch, leaving only a small safe area around the edges.
• After ~25 seconds, the Crushers will be replaced by special invincible Kogbold Drones that orbit clockwise around each safe zone, shooting fireballs towards the center.
• After ~35 seconds, the arena returns to normal and the Kogbold Drones vanish. Ferrus then shrinks the arena as its arrowhead barrage turns red and even more damaging. While the barrage is ongoing, Ferrus will periodically summon rows of evenly spaced diagonal laser beams that cross the entire arena, telegraphed in advance by red crosshairs.

If players survive this final phase, Ferrus will explode into a double ring of fire waves and leave its upgraded loot behind.
