Uber Keegan Boss Guide

Defeating the Dark Surge Tidemaster can be very rewarding, he has a large pool of exclusive and powerful Legendary equipment. 4 Edict "Uber" Keegan always drops the highly-variable Touch of the Dark Surge, and a Familiar Nexus. This is used to perform the Darkest Corrosion, which has an exclusive 15% chance to Desecrate equipment, potentially creating some of the most powerful equipment in the game.

Keegan awaits in the center of the Arena. Keegan deals damage in every damage type, so we recommend having maxed out resistances, potent damage mitigation, and defensive measures against Physical damage. Keegan's direct attacks can be mostly avoided by staying behind him or rotating around him quickly. Almost all of his abilities revolve around Spikes. Spikes are harmless while embedded into the floor, but abilities can launch them into the 4 cardinal directions, making them dangerous.

The fight itself is split into 3 Phases, separated by his transitional ability: Enforced Entropy. Keegan grows in strength with each passing Phase.

Keegan rotates through his Spike Gathering, Calamity: Blast, and the 3 Spike Formation abilities. Keegan can rarely use his Enforced Despair ability. This Phase ends when Keegan reaches 50% HP remaining, he then teleports to the top of the Arena to cast Enforced Entropy.

At 50% and 25% HP remaining, Keegan staggers and falls to the floor, he can be easily damaged but not killed in this time. After recovering, he teleports to the top of the Arena to begin channeling Enforced Entropy. A Divine Barrier forms at the bottom of the Arena, get behind this barrier before Keegan finishes channeling. If you are not behind this barrier, you shall die hundreds of times over in mere seconds.

If you die to this ability, do not respawn until it is over. After Keegan finishes using Enforced Entropy, he teleports to the center of the Arena. This marks the beginning of the next Phase.

After using Enforced Entropy for the first time, Keegan begins Phase 2 by using Calamity: Divide. Keegan adds this ability to his existing ability rotation. He also gains the Spike Barrage and Calamity: Focused Blasts abilities that can be used individually or combined. Keegan now has a higher chance to cast Enforced Despair. This Phase ends when Keegan reaches 25% HP remaining, he then teleports to the top of the Arena to cast Enforced Entropy.

After using Enforced Entropy for the second time, Keegan begins Phase 3 by using Calamity: Entrapment. Energy is prepared throughout the top and bottom borders of the Arena in an array, and after a delay the Energy erupts and travels upwards and downwards. Erupted Energy deals damage guaranteed to kill you on contact, and leaves behind a Trail.
Avoid death by heading to the bottom left or right of the Arena. The bottom left has little wiggle room but is completely safe from the Energy eruptions. The bottom right's Energy erupts prematurely, letting you move into where it was prior occupying. Wait within these areas of relative safety until after the residual Trail dissolves. Keegan has an even higher chance to cast Enforced Despair in Phase 3.

Uber Keegan initiates his Last Stand - Reinforced Entropy after reaching 5% HP remaining. After gaining temporary invulnerability, Keegan splits into 4 copies of himself. 3 of which are significantly smaller than the real Keegan. All of which channel Enforced Entropy. Divine Barrier does not appear, instead seek shelter behind the small Keegan opposite to the real one, all other positions erode away when subjugated to Enforced Entropy.

20% of Keegan's maximum life is restored after the Final Stand concludes, and no more bouts of invulnerability remain. Finish the fight quickly, you are close. Keegan's rotating abilities in Phase 3 are identical to Phase 2.
