Breaking the breakbar on the Retriever Projections will cause the Projections to temporarily get stunned and make it easier for the designated core pusher to get the cores away from the Projections and into the Ley Rifts.Rest of the players should be using their crowd control skills to break the bar on the Retriever Projections 1-2 players should be assigned to pushing the Construct Core around with their autoattacks knocking them into Unstable Ley Rifts around the room.Otherwise this phase will end only when all 5 Unstable Ley Rifts are destroyed by the Construct Core.

If the Construct Core is retrieved by the Retriever Projections or get knocked into the red outer ring, this phase will end immediately. Moving the Construct Core to the Unstable Ley Rifts is not an easy task as Retriever Projections will also spawn and try to retrieve the Construct Core. Each Unstable Ley Rift touched and destroyed by the Construct Core will cause the Construct to gain a debuff that increase your damage by 75% per stack in a later burn phase. The goal here is moving the Construct Core into the Unstable Ley Rifts by hitting it.

Five Unstable Ley Rift will also spawn around the room with an outer red ring enveloping the room. Once the Phantasms are destroyed, Construct Core will be visible and players can move it around by using their attacks. Failing to do so will result in a raid wipe. All you need to do is to have 2 player or more standing on each green circle and the Phantasm will be destroyed once the green circle times out. Each green circle will have a XeraвЂ™s Phantasm standing on it trying to protect the core. During this phase the first thing you will see is 3 green circles split across the room. Construct Core PhaseД¬onstruct Core Phase is only encountered if you remove Keep ConstructвЂ™s XeraвЂ™s Embrace buff and then break his breakbar. Breaking the breakbar will force it to enter the Construct Core phase. Once both stacks of XeraвЂ™s Embrace buffs are removed, the Keep Construct will gain a break bar. Each projection killed near the boss will remove a stack of XeraвЂ™s Embrace buff. The projections should be dragged to the boss and killed with AoEs while keeping them away from the other projections. The first two projections that spawn after 66% or 33% phase always come in pairs and then become staggered again. The first two mesmer projections will spawn around the same time but the ones after that will be staggered by about 15 seconds until the boss reaches 66% or 33%. Once they start merging to form the Insidious Projection, you cannot stop it.

Players should pay extra attention for this fixation mechanic and move away from each other to prevent the projections from merging.

Getting one Insidious Projection to form is not huge an issue but if you keep getting them then you have a high chance to fail since they have much more HP, hit hard, and do not disappear.

This can cause projection merges if the newly fixated person does not pay attention.

if the fixated person get downed, the Projections will switch their fixation to someone else in the raid.

Much like fixation on Slothasor, the player being fixated will have a purple icon above their head and see a message displayed across their screen вЂ“ You have been fixated.

This is especially important when you have two projections spawning at the same time like at 9:40 or once the boss finishes the 66% and 33% Magic Blast phase. This give you a good idea of where to move the boss so you can AoE down the spawning projection.

You can see where the next Mesmer Projection will spawn next since the statue they will spawn from glow in a bright light.

Each of the mesmer projections will have a white circle underneath them and if the circle of one of projection touches the other projection they will gravitate toward each other and merge to form an Insidious Projection that has a lot more health and will convert player boons to conditions. Starting at 9:40 on the timer, two mesmer projections will spawn from on statues on opposite sides of the room and become fixated on a random player similar to the fixation mechanic from Slothasor. Keep Construct gains this buff passively every minute and it cannot be removed (you will see the message The ConstructвЂ™s strength increases when this happens).

Gaining Power вЂ“ Each stack of this buff increase Keep ConstructвЂ™s direct damage by 10% and condition damage by 3%.

Removing 2 stacks of this buff causes the Keep Construct to gain a breakbar and enter a special mechanic phase.

XeraвЂ™s Embrace вЂ“ Maximum of 2 stacks, this can be removed by killing the Mesmer Projections described below.

Keep Construct has two buffs you need to be aware of.
