Uber Keegan Boss Guide


"Uber" Keegan is one of the Pinnacle Bosses of Torchlight Infinite. He is a Main Story Boss you encounter in Chapter 2 and the Endgame boss of the Dark Surge League (Season 1). He is one of the most challenging fights in Torchlight Infinite and can drop exclusive Legendaries and Familiar Nexus which is used for Double Corrosions (Desecration).

Defeating Keegan for the first time (Main Story Chapter 2 End Boss) is much easier than his other versions. He uses the same move set, but deals less damage and you have an unlimited amount of lives to defeat him. This Guide focuses on the Endgame Dark Surge Season 1 "Uber" encounter where he is much more difficult and every attempt matters.

To challenge the Endgame Dark Surge Season 1 "Uber" version of Keegan you need to collect 4 different Edicts (Edict: Dart, Edict: Dive, Edict: Ruin, Edict: Doom) and insert them into the Void Rift. Make sure you have a high amount of Damage and Survivability before attempting him.

Edicts to unlock the Boss fight

To challenge the Endgame Dark Surge Season 1 "Uber" version of Keegan you need to collect 4 different Edicts that have a chance to drop when defeating a Dark Surge Boss. Go to the Great Void and select Season 1 Timemaster. You have a chance of spawning a Dark Surge Boss by collecting Dark Surge Energy by killing monsters in Beacons. Once you have enough energy (shown by the dark surge icon being full purple and glowing) press V (default PC) or click the Dark Surge Icon to spawn a Dark Surge wave. If you're lucky a mini boss spawns and you have a chance to find one of the Edicts.

  • Edict: Doom

NOTE: Edict: Doom is much rarer and is only used to spawn the Timemark 8 "Uber" Keegan encounter.


Skills Breakdown

Erosion Cleave ( Auto Attack )

Keegan cleaves in front of him dealing medium Physical and Erosion damage, and low Elemental damage (all 3 combined). This attack also shoots Erosion Block projectiles dealing high Erosion and Physical damage on hit. The Erosion Blocks land on the ground and remain until detonated by an Elemental Blast (turning the blocks into small Erosion Spike projectiles dealing high Erosion and Physical damage on hit) or used in Safety Blast. The Erosion Blocks on the ground are safe to walk on; only the projectile blocks and the detonated blocks deal high Physical and Erosion damage.

Safety Blast

Keegan goes immune and teleports to the center of the arena. He then shoots 4 lasers at each of the corners of the arena, dealing high Elemental damage and spawning more Erosion Blocks. Then, still immune, Keegan begins channeling and pulling all the blocks towards him in a circular shield formation. The Erosion Blocks CAN hurt you while they are in motion towards Keegan. Once all the Erosion Blocks have been pulled in, he releases them out in a blast of small Erosion Spikes dealing high Erosion and Physical damage. Pay attention to the circle of Erosion Blocks around Keegan for an open spot. Stand there, giving yourself enough distance, to avoid the small Erosion Spikes when they are released.

Elemental Blast

Keegan raises his right arm and points at you releasing an Elemental Blast dealing Massive Elemental, Physical and Erosion damage. If the Elemental Blast hits an Erosion Block on the ground it detonates, causing an explosion of small Erosion Spike projectiles dealing high Erosion damage. Avoid this by moving to the side of Keegan when he raises his right arm or by staying behind Keegan.

Uber Triangle Blast *New Ability*

"Uber" Keegan pulls all Erosion Blocks in the arena around him in a triangle and then spawns 2 walls beside it. These walls deal no damage but can not be passed. Leap Attack, Blink, Rocket Jump, Blink Bow and Shadow Dash can be used to get over the walls. After a brief delay he shoots all the Erosion Blocks at you dealing high Erosion and Physical damage. The blocks remain in the triangle formation after being shot. Avoid this by using your Mobility Skill to bypass the walls, or simply moving in a crescent pattern with fast Movement Speed.

Triangle Explosion

Keegan pulls all Erosion Blocks in the arena around him in a triangle and spawns 3 pulsing light beams. He detonates all the Erosion Blocks releasing MANY small Erosion Spikes, dealing high Erosion and Physical damage on hit. Avoid this by running to the end of the arena to give yourself enough room to dodge and avoid all the small Erosion Spikes.

4 Rings

Keegan raises his right hand over his head and begins channeling. He then spawns 4 overlapping rings of Erosion Spikes. After a brief delay, the blocks begin to move to the edge of the arena in 4 different directions making a cross. If hit, the spikes deal high Erosion damage. Avoid this by stepping out of the Erosion Spikes path or using your Mobility Skill.

Armageddon

At 50% and 25% HP Keegan falls to the floor (you can still damage him). He then stands back up and teleports to the north border of the arena and starts channeling. A Safety Bubble spawns at the south border of the arena. Make sure you are standing in this bubble before Keegan is done channeling Armageddon. You can tell when it's over by watching his hands. He moves them to his side one at a time very dramatically. If you are not in the bubble when Keegan releases Armageddon, you die! If it kills you, don't respawn until the animation finishes.

Box Slam

Starting right after the first Armageddon, Keegan uses Box Slam. He teleports to the center of the arena and slams the ground. Make sure you are not standing on or right in front of him. After slamming the ground 4 Elemental Trails are released that move toward the arena's border in a cross formation. The trails form 4 boxes inside one larger box on the ground. Avoid making contact with these Elemental Trails as they deal medium Elemental damage if touched, and periodically after. There is a brief safe period after making first contact with an Elemental Trail on the ground that allows you to safely stand on and pass over other trails.

The Center of the slam deals EXTREME Physical, Elemental and Erosion damage.
The Tip of the Elemental Trails deal high Elemental damage.

Block Barrage

Starting in Phase 2 Keegan stands still raising his right arm over his head and begins channeling Block Barrage which rapidly shoot Erosion Blocks at your current location dealing high Erosion and Physical damage. Avoid this by staying mobile and never backtracking.

Trailing Blast

Starting in Phase 2 Keegan stands still raising his right arm in front of him, firing 3 Elemental Blasts that leave an Elemental Trail on the ground dealing high Elemental damage. The Elemental Trails deal medium Elemental damage if touched, and periodically after. There is a brief safe period after making first contact with an Elemental Trail on the ground that allows you to safely stand on and pass over other trails. The trails remain on the ground for 5 seconds.

The Elemental Blast detonates any Erosion Blocks it makes contact with, releasing small Erosion Spikes dealing high Erosion and Physical damage on hit.

Wall Combo

After 50% Health Keegan gains the ability to use Wall Combo. He teleports to the left wall and uses Block Barrage and Trailing Blast. Avoid the rapid fire of Erosion Blocks by constantly moving forward. You can run to a corner or one side of the area to leave the Erosion blocks there and out of the way for the incoming Trailing Blast. Run to the other side of the arena and plan to side step each of the 3 Trailing Blast shots. Keep in mind if any of the 3 blasts make contact with any Erosion Blocks, many small Erosion Spikes flood the arena. Keep a constant eye on the ground as well to avoid standing in the Elemental Trails.

Keegan's Turret

Keegan's Turret is the most frustrating mechanic in this encounter. Keegan goes immune and teleports to the center of the arena. 4 start points spawn around the arena at 4 points in a cross formation. After a short period, Keegan begins channeling his turret from the 4 points telegraphed by 4 orbs, 2 light and 2 dark, in a clockwise rotation. Run and hug one of the arena border walls in between the 4 start points. Do your best to move while staying in the center of the beams and avoiding all the other hazards such as, Trailing Blast, Erosion Spikes and Keegan himself teleporting and using Erosion Cleave during the turret. If you make contact with the turret, you die! If this happens do not respawn right away; wait for Keegan to finish casting his turret. Spawning right away leads to another death.

This mechanic's hit boxes are not consistent, so you may die when it looks like you are safe. This is very frustrating so plan to save a life for this mechanic!

World's End

At 25% HP Keegan casts his 2nd Armageddon. After that he teleports to the center of the arena and begins to channel World's End. The north and south borders of the arena spawn yellow Elemental Balls that are all lined up. After a brief delay all the Elemental Balls fire to the other side of the arena, If hit they kill you! Luckily for us, Keegan doesn't know about the left wall! Run to the Left wall and hug the bottom corner. This is a safe spot from all the Elemental Balls. Keep in mind while all the balls are in motion Keegan continues to use his attacks and may fire a Blast at you. Any Erosion Blocks hit by the Elemental Balls release many small Erosion Spikes. This may result in our safe space not feeling so safe. Do your best to hug the left wall and jump and avoid all the projectiles while not standing on any of the Elemental Trails.

Keegan's Shell Game

When Keegan reaches 5% HP, he goes immune and splits into 4 copies of himself. The real Keegan has a Health Bar over his head and has a slight yellow glow. Run to the copy opposite of the real Keegan, and stand in the Safety Bubble around him. If you are not in the right Safety Bubble, you die! After this Keegan regains 20% HP and rotates through all of his abilities.


Keegan's Mechanics

Once you enter the Boss Arena you find "Uber" Keegan in the center. Do not run straight at him at the start of the fight. Instead run in with a curved path to avoid his first Erosion cleave. Try to stay behind "Uber" Keegan as much as possible. "Uber" Keegan moves and attacks much faster than his other versions. It is highly recommended to have maxed out Fire, Cold, Lightning, and Erosion Resistance. Having high Physical damage mitigation also helps since all of "Uber" Keegan's attacks deal Physical damage.

The fight itself is split into 3 Phases with a Phase Transition. After each transition "Uber" Keegan gains new abilities. Throughout the entire fight "Uber" Keegan spawns and detonates Erosion Blocks dealing high Erosion and Physical damage if hit.

You can skip a large portion of this fight's mechanics and attacks if you have really high Damage. Sadly there are a few forced Phases at 50%, 25% and 5% HP. With insanely high damage you can overlap the transition of Phase 1 and 2 and only have one transition phase. "Uber" Keegan is always immune while casting World's End and Shell Game at the end of the fight, so this can't be skipped.

Phase 1

"Uber" Keegan begins the fight in the center of the arena and rotates through his basic attacks; Erosion Cleave, Safety Blast, Elemental Blast, Triangle Blast, Triangle Explosion, 4 Rings and very rarely Keegan's Turret. As he rotates through his move set he spawns more and more Erosion Blocks. While on the ground these blocks do not hurt you. In motion they deal high Erosion and Physical damage on hit. Do your best to avoid all his attacks and skills while damaging him. At 50% HP he goes immune and casts Armageddon.

Phase Transition ( Armageddon )

At 50% and 25% HP Keegan falls to the floor (you can still damage him). He then stands back up and teleports to the north border of the arena and starts channeling. A Safety Bubble spawns at the south border of the arena. Make sure you are standing in this bubble before Keegan is done channeling Armageddon. You can tell when it's over by watching his hands. He moves them to his side one at a time very dramatically. If you are not in the bubble when Keegan releases Armageddon, you die! If it kills you, don't respawn until the animation finishes.

Note: "Uber" Keegan gains new skills after each Phase Transition.

Phase 2

After the 1st Armageddon "Uber" Keegan teleports to the center of the arena and uses Box Slam. Make sure you are not standing on, or in front of him. This move is added to all his Phase 1 skills with Block Barrage, Elemental Trailing Blast and Wall Combo. "Uber" Keegan is more likely to cast his Turret in Phase 2.

This Phase is shorter but much more chaotic than the 1st Phase. Be sure to have good awareness as the arena fills up with Erosion Spikes and Trailing Blast lines quickly. Do what you can to avoid all "Uber" Keegan's attacks while damaging him to 25% or lower. At this point "Uber" Keegan cast his 2nd Armageddon, be sure to get into the safety bubble!

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

Phase 3

After the 2nd Armageddon "Uber" Keegan teleports to the center of the arena and begins to channel World's End. The north and south borders of the arena spawn yellow Elemental Balls that are all lined up. After a brief delay all the Elemental Balls fire to the other side of the arena, If hit they kill you! Luckily for us, Keegan doesn't know about the left wall! Run to the Left wall and hug the bottom corner. This is a safe spot from all the Elemental Balls. Keep in mind while all the balls are in motion Keegan continues to use his attacks and may fire a Blast at you. Any Erosion Blocks hit by the Elemental Balls release many small Erosion Spikes. This may result in our safe space not feeling so safe. Do your best to hug the left wall and jump and avoid all the projectiles while not standing on any of the Elemental Trails. "Uber" Keegan then rotates through all of his abilities until defeated.

After World's End, get "Uber" Keegan to 5% HP. He then goes immune and splits into 4 copies of himself. The real Keegan has a Health Bar over his head and has a slight yellow glow. Run to the copy opposite of the real Keegan, and stand in the Safety Bubble around him. If you are not in the right Safety Bubble, you die! After this Keegan regains 20% HP and rotates through all of his abilities.

Note: You can use Elimination or other execute talents or modifiers to speed this phase up.
