Before you start

Keep your eye out for Lost Journal Pages throughout the fractal!

Start: You think this is Cliffside

Kill the four Veteran Chanters at the beginning to open the gate to the right side of the map. The fastest person may rush ahead on the path leading to the next encounter, which involves a small jumping puzzle and kitty golems that Knockback the player off the platforms. As soon as one person reaches the checkpoint, everyone else can /gg and resurrect at the platform near the Chaos Anomaly .

While the video showcases the skip for Thief any class can execute the skip effectively with the help of blocks and reflects.

Stack Might before approaching the four K1T-A golems, pull them together to kill them so that the Chaos Anomaly spawns. Alternatively, you can check if you still need one of them for the Kitty Compactor and focus on it. Every 25% health, The Chaos Anomaly will become immune to damage and you have to kill K1T-A golems again to continue. With every phase there will be one less K1T-A golem but the remaining grow in strength. The final single golem at 25% health has about 1.5m health and is a champion. This is the one that will count towards the achievement. The last golem to be killed is the one that will not spawn in the next phase.

Pay attention to the Knockback zones from the small JT-12 golems and look out for Flux Bombs, the debuff can be hard to notice on the mosaic ground.

Blizzard path (Forest)

You will need to light four bonfires on the path leading to the end boss. The Enlighten special action key has unlimited charges, which means the forest may be soloed.

You could stack Stealth to skip the mobs although it’s usually not necessary. Learn to dodge the tentacles Knockback. Mobility skills and Executioner Axe Toy are very good here.

Legendary Brazen Gladiator

The end boss is only vulnerable when his protective bubble is removed by pulling him into the moving purple areas.
He will also apply a group-wide Daze if he hits anyone with the third hit of his auto-attack chain. Avoiding this is the highest priority during the fight. Either use blocks, dodges and skills that make you invulnerable or - most commonly - bring permanent Stability. It may also be avoided by not standing in front of him when his attack hits. Learn to recognize the animation.

By bringing permanent Stability and reflects, enough DPS or a dedicated healer the mechanics of this fight can easily be ignored.

Note that you can take aggro from him by walking inside his hitbox and cancel the third auto-attack by moving out before.
Another trick is to bypass the damage from purple zones by jumping repeatedly.

Starting at 50% health, he will randomly start a pulling attack which can be prevented by breaking his defiance bar. Save your crowd control skills for this.

Also pay attention to the small JT-12 golems and their AoEs as they apply Knockback and can shove you off the platform.
