The Siegecrafter Blackfuse fight consists of 2 main targets: Blackfuse himself and Automated Shredders.
Blackfuse should be tanked near the north-western conveyor belt with the Shredders just away to prevent healing.
Two teams should be assigned to alternate going onto the conveyor belt to defeat one of the weapons (the suggested order is linked in The Assembly Line section).
Any Weapons not killed will use their abilities from the second conveyor belt.
This fight has no phases, and you need to deal with Siegecrafter Blackfuse on the main platform.
EVERYONE
DON'T GET HIT
A sawblade is thrown towards a random player and lasts until removed by an Activated Electromagnet's Magnetic Crush.
Players that come into contact with a sawblade are knocked back and take massive Physical damage from Serrated Slash.
TANKS
SOLO SHREDDERS
Blackfuse will periodically summon Automated Shredders that have 3 abilities:
Reactive Armor - a passive ability that reduces damage taken by 90%. This can be negated by a tank with stacks of Electrostatic Charge picking them up and killing them.
Death from Above - the shredder takes flight and slams to the floor, dealing massive damage to all players within 15 yards. For 5 seconds after landing, they take 200% increased damage.
Overload - all players not on the conveyor belt will take small damage and the shredder will buff its damage dealt by 30%
If a shredder gets within 35 yards of Blackfuse, he will use Automatic Repair Beam, healing it for 5% of their max health every 3 seconds.
Tanks should solo these adds, away from the boss, utilizing the damage buff.
Two groups should be assigned to go take on the Assembly Line, swapping to combat the Pattern Recognition debuff.
Note: Some classes (such as Hunter with Disengage, Rogues with Shadow Step) can make it up without getting the debuff.
You can choose your own mob kill order to decide what to mechanics to deal with.
Here is one suggested kill order:
Wave 1: Missile
Wave 2: Missile
Wave 3: Missile
Wave 4: Missile
Wave 5: Missile
Wave 6: Mine
Wave 7: Missile
Wave 8: Missile
Wave 9: Laser
Wave 10: Missile
Wave 11: Missile
Wave 12: Laser
KILL A WEAPON
AND DODGE LASERS
A player can jump into a pipe to be transported onto the conveyor belt.
After using this pipe, they will gain the Pattern Recognition debuff, preventing them from using the pipe for 1 minute.
Once up on the platform, players will need to kill one of the disassembled weapons before they reach the other end of the belt while dodging lasers.
Players will die if hit by a Matter Purification Beam.
Near the end of the belt, players can jump into the pipe to return to the main platform.
EVERYONE
AVOID SHOCKWAVES
EVERYONE
KITE BEAM
When the Laser Turret is not killed, it will target random players with Superheated.
This is a beam that will chase the player and leave a trail of fire that applies a small Fire DoT for 7 seconds. This will stack for every second spent in the fire, up to 20.
The fire will also damage Automated Shredders.
EVERYONE
WATCH THE MAGNET PULL
EVERYONE
MOVE WHEN FIXATED
Dissembled Crawler Mines that make it through the first conveyor belt will turn into Crawler Mines.
Several of these leap down onto the platform and fixate on a random player.
For the first minute, they can be CC'd due to Break-in Period.
After this, they will gain Ready to Go!, becoming immune to CC's and speeding up their player chase.
If they reach a player, they will cast Detonate! This deals moderate Fire damage to all players and knocks them into the air.
The boss can be tanked on top of their spawn, enabling them to be cleaved down with CC as they arrive.
