Tidemaster - Keegan is a Pinnacle Boss introduced in Torchlight Infinite's Season 1: Dark Surge release. Keegan is also encountered in the story, as Chapter 2's final boss. Keegan's endgame boss fight is among the most challenging encounters in the game, this guide teaches you everything you need to know about it.

Keegan has 3 difficulty levels, though the first is within the Story and is irrelevant to endgame. This guide focuses on the 3 Edict variant of the fight. Challenge the Tidemaster by offering Edict: Dart, Edict: Dive, and Edict: Ruin to the Great Void. Edicts rarely drop from bosses summoned by the Dark Surge.

Offer the 4th Edict - Edict: Doom - alongside the other 3 to challenge the most difficult version of the fight, read our dedicated guide for 4 Edict "Uber" Keegan here!

Defeating the Dark Surge Tidemaster can be very rewarding, he has a large pool of exclusive and powerful Legendary equipment. Keegan always drops the highly-variable Touch of the Dark Surge, and can sometimes drop a Familiar Nexus.

Skills Breakdown

Keegan swiftly slashes in front of him automatically in close quarters combat, dealing mediocre area damage in front of him while launching 3 Spikes into the ground that deal significant impact damage with little coverage. Spikes remain in the ground until launched by Keegan's other abilities. Avoid this attack by being behind or to the side of Keegan.

Keegan's Mechanics

Keegan awaits in the center of the Arena. Keegan deals damage in every damage type, 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.

Phase 1

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.

Phase Transition

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.

Note: Keegan gains new abilities after each Phase Transition.

Phase 2

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.

Note: Keegan can not be killed here. He always goes immune and forces Phase 3.

Phase 3

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 now has a higher chance to cast Enforced Despair. End the fight quickly, you are close. There are no more bouts of immortality for Keegan from here. This Phase is otherwise identical to Phase 2.

Note: You can use Elimination or other execution modifiers to speed this Phase up.
