Start & Ankle Seals

Kill the Cultists but take the Cultist Hammer before finishing the last one to get a hammer charge.

Take the portal to above (…or walk) and destroy the two Ankle Seals using hammer Skill 4. Both seals have to get hit two times, do not finish mobs unless you need a charge.

Use /gg afterwards and stay dead until the Elementalist, Guardian, Thief reaches the Chest Seal.

Chest Seal

As soon as the Elementalist did /gg too, everyone can resurrect and will respawn in front of the Chest Seal with a new Cultist Hammer ahead of you.

It will take five hits to break the chest seal. If you see somebody running ahead and placing a White Mantle Portal Device to the Arm Seals, try to get a hammer charge before taking it to above. In an ideal scenario the group kills the cultists one by one and uses every charge gained so that no time is lost due to waiting for respawns. This implies, that the party can run a healer to better sustain the damage - with no penalty in speed for this encounter.

Arm Seals

This is a matter of timing, so look out for the White Mantle Portal Device and the hammer carrier. In a perfect world you use the portals one by one, and Renegade placing Inspiring Reinforcement , giving Stability to the hammer carrier and not getting knocked back, resulting in faster seal breaking.

During the portal jumping, keep Cultist’s health as low as possible but only finish them when a hammer charge is needed. If you run out of portals simply run together. Ideally, both seals take three hits to be destroyed—two portals are more than enough.

Type /gg after finishing both seals and stay dead. If you wipe before both seals are destroyed, they will reset to full health.

The way up

Do not resurrect yourself yet, wait for the Revenant, Elementalist, Guardian or Thief to finish his portal and do /gg himself again or you will be stuck with a useless person for the entire end fight.

After the whole party /gg’ed, resurrect and place White Mantle Portal Device at the revival position. Blink up, and open the portal. Note that after the Status Reset change you cannot blink up and /gg anymore, since it will clear the portal.

Arch Diviner

Take the portal up and start the fight against the Arch Diviner. His defiance bar appears very shortly but frequently, try to break it as often as possible to benefit from Exposed.

Every 25% of his health, you will need to collect a Cultist Hammer charge similar to before by killing one of the four spawned Cultists and hit the final Seal to make the Arch Diviner vulnerable again. Cultists apply a lot of conditions so kill them fast and try to stay out of their aggro range.

Do not get caught in any of the Arch Diviner’s voidzones, otherwise you will be teleported and trapped inside a distant cage which messes up positioning. Also, try to stack on him as he teleports to the furthermost person.
