Upon reaching the end of the Tomb’s Main Quest, you’ll go toe to toe with the final boss, known as the “Sentinel Artifact.” We’ll show you how to defeat this enemy inBO6 Zombies,including how to start it and what preparations you need to make.
How to start the final boss fight in BO6 The Tomb
To unlock the final boss fight inBO6 ZombiesThe Tomb, you must acquire and upgradethe Ice Staff. Then, you’ll need to use this Elemental Staff to complete four trials with the Amalgam, Parasite, Doppelghast, and Vermin statues. If you need help with these objectives, check out our complete guide on theTomb Main Quest. Once you’ve obtained the Ice Staff and completed the statue challenges, head to thebroken bridge at Dark Aether Nexus to start the final boss fight.
Interact with the pedestal there, which will fix the bridge. Cross it, and you’ll notice a mirror-like object in the center. You’ll see an option to ‘Start the Final Encounter.’ But, before you begin this venture, it’s crucial to make some preparations first.

Best weapons and abilities to use for Tomb boss
You can use a few weapons in the Sentinel Artifact fight, including theGPMG-7 LMG or ASG-89 Shotgun. It’s also a good idea touse the Ice Staff,which you should already have from the previous Main Quest objectives.
Now that I’ve spent some time in this showdown, I believe it’sbest not to bring in the Mustang and Sally build. As much as I love this dual weapon, I learned it does not damage the Sentinel Artifact. It can only be damaged with bullet-based weapons, so anything with explosives won’t do you good here.

As for other preparations, here’s a few things you need to have:
Without the mandatory upgrades or items, the fight will be brutal, and you may go down in no time. The other upgrades, like GobbleGums and Mutant Injection, aren’t all that necessary, but they are nice to have. For example, you can use Perkaholic to reclaim your perks after a revive or use Free Fire when shooting at the boss. You can still get by without them, so don’t stress if you don’t have these gums.

How to defeat the final boss in BO6 The Tomb
For a quick overview of what to expect during this final showdown, here’s a breakdown of each phase:
Once you’ve begun the battle,the Sentinel Artifact will be immune to your attacks while in an orange/red-colored state.Don’t waste your time shooting at it; focus more on the zombies for now.

Avoid the boss’ beam attackas it circles around the battlefield.Take cover near the pillars on the ground, where the boss won’t be able to hit you. Use the Elemental Staff’s Ice Storm to eliminate hordes of zombies instantly.
Wait until the Sentinel Artifact glows purple/blue to deal damage to it.You won’t have much time here, and you must unleash as many bullets as you’re able to to get its health bar down. This is where Aether Shroud comes into play, hiding you from zombies temporarily. You can also use the Free Fire GobbleGum for maximum ammo.

The Sentinel Artifact will go back and forth with its immune and vulnerable forms throughout the match.The enemy will also split into multiple parts, unleashing more beam attacks. Repeat the process of taking cover at the pillars and striking the artifact when it’s in its purple/blue state.
By the mid-point, you’ll have to eliminate glowing red zombies.The Sentinel Artifact will be hiding inside them, so you must try to get it out. Once you do, spray a ton of bullets onto it. You’ll need to repeat this step a few more times, as the boss will continue to latch itself onto a specific zombie or an Elite Zombie.

Keep your distance from the glowing red zombies, as they can bring you down. You’ll have to eliminate them quickly, or the zombies will respawn. Eventually,the Sentinel Artifacts will shoot multiple beams of light against the wall.
