Finally, they emerge completed on conveyor belts along the southeast wall of his room, where they attack players.

Boss Strategy

At all times during this fight you want to make sure that you have got 1 tank on Siegecrafter Blackfuse and you have another tank on Automated Shredders, however if both Blackfuse and a Shredder is alive they should not be coming within 35 yards of each other at any point during the fight due to the Automatic Repair BeamAutomatic Repair Beam ability that you will have to deal with. You must ensure that you are tank switching due to the Electrostatic ChargeElectrostatic Charge debuff. You should not worry too much about the Shredders as your tank should be able to do enough damage to them in order to kill them off in time before you have to perform a tank switch. If this is not the case then you will want to get your DPS to aid on killing the Shredders.

Whenever you kill one of the Shredders your current Blackfuse tank will have to use a cool down or one of your healers will have to use a cool down on the tank due to the damage that is going to be output from Protective FrenzyProtective Frenzy.

Your Shredder tank should also be aware of the Shredders Death From AboveDeath From Above ability as this can cause a lot of damage to any player that gets hit by it. if your tank is struggling to kill the Shredder then they can also consider using some of the fights abilities against it, as they will deal damage to the shredder. These abilities are Serrated SlashSerrated Slash, SuperheatedSuperheated and also Magnetic CrushMagnetic Crush when it pulls the sawblades off the platform as these are able to damage the Shredders.

Boss Strategy – Conveyor Belts

Firstly due to the Pattern RecognitionPattern Recognition debuff you will want to set up two groups of 2 or 3 DPS players depending on how good your DPS is in order to go on the conveyor belts in a set rotation. You need to do this as new adds will spawn roughly every 40 seconds and because of the debuff, the same players are not able to go on the conveyor belt every time. Anyone that is on the conveyor belt will not take any damage, unless they are to be hit by the Matter Purification BeamMatter Purification Beam.

When it comes down to which add you want to kill, it will be entirely based on what works best for your raid and what abilities you find easier to manage. The one thing we will suggest is that every now and then you will have to allow a Deactivated Electromagnet through the conveyor belt as the Magnetic CrushMagnetic Crush ability is really useful for removing the Sawblades from the platform and giving your raid more room to move about.

Boss Strategy – Siegecrafter Blackfuse

Throughout the fight the main ability that your raid is going to have to deal with is Launch SawbladeLaunch Sawblade and the Sawblades that it will create. These can deal a high amount of damage and will take up a fair amount of room on the platform, and you will need this room during the fight in order to avoid abilities that are being cast at you from the conveyor belts. As previously mentioned you will want to allow Magnetic CrushMagnetic Crush to go off several times during the fight and when it does go off you will want to position yourselves in such a way so that no one is standing between the Electromagnet and the Sawblades it is going to pull in as they will hit you and deal very high amounts of damage.

Previously we spoke about Death From AboveDeath From Above and tanks avoiding this ability, however your whole raid in general should watch out for this ability and if they are standing in the zone where it is going to land then they need to move away as soon as possible. As well as Death from Above, pleayer will also have to deal with the OverloadOverload that the Shredder will be casting throughout the fight. This damage can not be avoided, unless you are on the conveyor belt, and will just require your healers to heal through the damage that it is dealing to your raid. The longer a Shredder stays alive the harder its OverloadOverload ability is going to hit due to the 30% increase in damage every time it is cast. This should not be a massive issue as long as your tanks kill the Shredders in a decent amount of time and they do not go within 35 yards of Blackfuse and get healed by Automatic Repair BeamAutomatic Repair Beam.

Another form of damage that your raid is going to have to avoid will be coming from the Activated Missile turrets and their Shockwave MissileShockwave Missile ability. The damage that this can deal is very high and the Shockwave MissileShockwave Missile ability could be one of the harder ones to deal with so we recommend that you try to avoid not killing this add on the conveyor belt. If however you do let the Turret through then you should always be aware of where the effects of the shock wave are on the floor and react accordingly to move out of them.

For the second time in this raid you are going to have to deal with Crawler Mines on a boss. If you let the Mines spawn and jump onto the platform then the players that get fixated by them must make sure they kite them around and keep them out of range of Blackfuse otherwise he will heal them with Automatic Repair BeamAutomatic Repair Beam. You should be aware of how long is left on the Mines Break-in PeriodBreak-in Period as using roots, stuns and snares can be really beneficial when it comes to killing the mines. When the mines are Ready to Go!Ready to Go! you will want to kill them as soon as possible in order to reduce any risk of people getting killed by the damage they deal.

Finally you will have to be aware of the Activated Laser Turrets and in turn their SuperheatedSuperheated ability. Players should keep an eye out on where they are able to move if they do get targeted by the beam and should make use of any space that the raid, in general, can not really make use of for moving from the Sawblades. Your tanks should also keep an eye out on this location as the beam will be able to deal damage to the Shredders if they happen to be hit by it or stand in the void zones that are left behind.
