Vigilant Guardian

This is a three phase encounter where you will fight against the defenses at the enterance of the raid and finally fight against the Vigilant Guardian.

Phase 1: Kill adds as they spawn and move inside barriers when the boss casts Exposed Core.
Phase 2: Take the boss down to 15% and avoid mechanics.
Phase 3: Kill it before it kills you.

Your goal as a raid in this phase is to kill adds near an Automated Defense Matrix. Each time an add dies their Energy jumps into the nearest valid inactive add.

You need to have made an Automated Defense Matrix active before the boss is at full temperature (extra resource bar) and casts Exposed Core.

Avoid Deresolution Beams that are targeted on players and Refracted Blasts.

Tank & Kill Adds near this to empower it
Once it has received 16 energy a shield will spawn providing 80% damage reduction from Exposed Core
[Heroic/Mythic] This will reduce damage taken from mobs inside by 90%.

[Heroic/Mythic] The Automated Defense Matrix will become active after Exposed Core has finished and will channel Sear into random players.

When the Automated Defense Matrix dies it will drop an Unstable Core. One player will need to carry this up the ramp and to the boss. Each one of these will deal 20% of damage to the boss.

Phase 2 begins when the boss is at 40%.

The boss will roll out from the wall and become active.

You can get run over by the boss as it rolls down. Don't die a stupid death.

Pneumatic Impact - Tanks should swap on each cast.

Matter Dissolution - A player is targeted and orbs will converge on their location. Avoid!

When the boss reaches 15% Phase 3 will begin.

Blood Death Knight

Anti-Magic Zone is best used to mitigate raid damage taken from Exposed Core (Phase 1) and Core Overload (Phase 3).

Death Grip, Gorefriend's Grasp and Abomination Limb are all useful tools to displace the Point Defense Drones and cancel their Searing Ablation casts.

[Heroic/Mythic] Gorefriend's Grasp can be useful to grip adds out of the shields so that they do not take reduced damage.

This is a three phase encounter where you will fight against the defenses at the enterance of the raid and finally fight against the Vigilant Guardian.

Phase 1: Kill adds as they spawn and move inside barriers when the boss casts Exposed Core.
Phase 2: Take the boss down to 15% and avoid mechanics.
Phase 3: Kill it before it kills you.

Your goal as a raid in this phase is to kill adds near an Automated Defense Matrix. Each time an add dies their Energy jumps into the nearest valid inactive add.

You need to have made an Automated Defense Matrix active before the boss is at full temperature (extra resource bar) and casts Exposed Core.

Add Energy

When an add dies it will transfer energy to a nearby add.

Volatile Materium will transfer 1 Energy into the closest inactive Point Defense Drone (Requires 4 Energy to activate).

Point Defense Drones/Pre-Fabricated Sentries will transfer 4 Energy into the closest inactive Automated Defense Matrix (Requires 16 Energy to activate).

If all of the adds near you are active the Energy will go to the nearest inactive one in another add camp. Be mindful of other Automated Defense Matrix adds if they are active as they will need to be killed after Exposed Core.
