Walkthrough[edit]

This is a multiphase fight with a good bit to it. Be ready as you enter into this Vault. Reload everything and equip your best weapons. This is the beginning of the Raid boss fight. This one has significantly more health than its previous version.

The Sentinel Phase 1 - Eridium[edit]

Be careful throughout this phase as there are no other enemies for you to get a second wind off!

Right now the Sentinel is going to move fairly slowly and deliberately. There are only 2 abilities you need to worry about. The first is the Staff Deflect. The Sentinel will use its staff to bounce the bullets you fire at it back at you. Watch for it to enter a pose to see it is about to do so. This can save you a lot of damage. You can overcome with this splash damage going off nearby it. Its second attack will have it simply run toward you and then use an overhead swing of its staff to attack you. It can also have its staff swing around its body to attack anyone very nearby. It can also fire Homing Slag Balls. These frequently go over your head then loop behind you to hit you in your back.

Just keep some distance throughout this fight. Aim for the head.

When you have drained the shield bar, the Sentinel will rise up in the area. Watch out as it will come down and unleash a devastating shockwave. Hide behind any of the pillars in the area to avoid in the incoming wave of damage. This will lead to the second phase of the fight.

The Sentinel Phase 2 - Fire[edit]

Having drained the first shield bar, the Sentinel will change to its second phase. Its shield bar will completely refill.

It will have all the attacks it had prior. Change the Homing Slag Ball to Homing Fire Ball now. It has a few more attacks as well: Fire Charge is likely the first one you will deal with. The Sentinel will come charging directly at you. Next is Ground Explosion. This seeking attack will cause a massive pillar of flame to appear beneath each Vault Hunter. There are a number of axillary fiery explosions around it as well. Finally there is Fire Storm. The Sentinel will hover in the area and loose a barrage of fireballs at the nearest Vault Hunter.

There are now a number of Guardian and [[Borderlands Pre-Sequel: Guardian Cheru|Guardian Cheru] running around. These add some damage but are very useful for recovering with a second wind if you are down.

When you have drained the shield bar, the Sentinel will rise up in the area. Watch out as it will come down and unleash a devastating shockwave. You need to get behind any of the pillars to avoid damage. This will lead to the third phase of the fight.

The Sentinel Phase 3 - Ice[edit]

The Shield will stop regenerating. It retains all its previous attacks, changing their element over to Ice now. There is only one new attack but it is hard to deal with. Eye Lasers. These will inflict Cyro damage to anyone unfortunate enough to get caught by them. Once again, you will need to drain down its shield to trigger the next, and final, transition.

The Sentinel Phase 4 - Eridium[edit]

This is the final form of the Sentinel. All previous attacks are changed to Slag elemental and it gains its final attack. This is a staff projectile. The Sentinel will throw its staff into the air where it will split into 5. These will home in and slam down on you. Keep on the move and keep running to avoid the worst of it.
