Main Quest

The main quest for The Tomb has our main crew of Weaver, Maya, Carver, and Grey looking deep within the Catacombs of Avalon for the Sentinel Artifact.

Requirements

This main quest can be completed with any number of players and cannot begin until you have opened the gateway to the Dark Aether Nexus by following the on-screen markers.

is also a great choice if you'd prefer. Although you don't have to choose these exact starting weapons, be sure to spawn in with an AR or LMG with high damage and ammo capacity as this will be critical for the Boss Fight.

Solo GobbleGumsCo-op GobbleGums

These GobbleGums are just a recommendation and not required to complete this main quest in anyway, only to make things quicker and/or easier throughout the quest.

Step 1: Obtain the Ice Staff

There are three parts required to build and obtain the Ice Staff, however, you can use a GobbleGum for a chance to get it out of the box without needing to build it, skipping this step entirely.

Monocle

Progressing to Round 8 will spawn a Shock Mimic, which, once killed, will drop the first piece needed to build the Ice Staff, the Monocle.

Head Piece

At this point, you must have entered the Dark Aether Nexus at some point in your game before progressing.

Head to the Neolithic Catacombs where is located to find a Dark Aether Lantern on the ceiling of the catacombs in one of three locations. You want to shoot this lantern until it is on the ceiling in front of the Crafting Table in that area.

After being shot, the lantern will take about a minute to re-locate.

Once in front of the Crafting Table, it will begin to illuminate Roman Numeral Symbols on the wall left of the Crafting Table where you will need to shoot each symbol in numerical order. Below is an image to help if you don't know how to read Roman Numerals.

Roman Numerals

If you fail to shoot them in the correct order you will get a few more tries starting from the point you failed to shoot the correct symbol.

After shooting the symbols in the correct order, this will begin a set of lockdowns where you must kill the zombies spawned by the purple wisp, moving to a different location in the area for each lockdown with the final lockdown being in front of the symbol wall.

These lockdowns will spawn Shock Mimics and Doppleghast so be sure to be prepared to kill these special enemies.

Once all lockdowns have been completed, the Head Piece for the Ice Staff will rise from the ground in front of the Roman Numeral Symbol wall for you to collect.

Head to the Tombs where is located where you will have to repeat the exact same steps as for the Head Piece, this time with the lantern ending on a pillar in front of a wall with a bull on it where the Roman Numerals will be illuminated.

Once illuminated, shoot the symbols in numerical order this time for only 8 symbols, triggering a set of lockdowns which once completed will spawn the Staff Piece out of the wall with the Roman Numerals.

Construct the Ice Staff

Head to the Dark Aether Nexus and interact with the structure in the middle of the area where you will be able to place the staff parts beginning a protection lockdown where you must protect the staff from taking too much damage before being constructed.

Dark Aether Structure
Dark Aether Structure

This lockdown spawns in a lot of zombies, with the focus being on the zombies containing purple eyes and smoke emitting from them indicating they will only go after the Staff of Ice. Focusing on killing those zombies, and parasites while hording the rest of them can make this much easier.

Once the lockdown is completed, you can interact with the structure to pick up the Staff of Ice Wonder Weapon.

If you failed the lockdown, you can try again on the next round.

Step 2: Upgrade the Ice Staff

You must freeze three separate Dark Aether Lanterns, one in the Neolithic Catacombs, Ossuary, and Subterranean Temple all within 10 seconds. This can easily be done by first shooting the lanterns with a bullet weapon so that they are in an ideal location for you to quickly shoot them when running between rooms as seen in the images below.

Once completed, head into the Dark Aether Nexus where you must shoot three floating rocks with symbols on them with the Ice Staff to lower them allowing you to look at and make note of the symbol on the rock. These rocks can spawn in different locations within the Dark Aether Nexus each game.

Rock with a Symbol
Rock with a Symbol

You will know if its a rock with a symbol if you get a hit marker when shooting it, each rock has it's own symbol and the symbols can be different from game to game so make sure to note them down. Image with all the symbols below.

Once you have your three symbols, leave the Dark Aether Nexus and check all the Gateways to the Dark Aether Nexus in the main map until you find one that has been blocked off. This blocked Gateway will have multiple symbols on it, three of which will be the symbols on the rocks in your game that you must shoot.

After shooting the symbols the Gateway will re-open allowing you to re-enter the Dark Aether Nexus spawning you on top of a floating platform, if you have shot the correct symbols, there will be symbols underneath the Gateway and a purple orb you can interact with once you enter.

Purple Orb

If you have shot the wrong symbols, the floating platform will drop you, potentially killing you and you will need to find a new blocked off Gateway on the following round to try again.

After interacting with the purple orb, it will lower and begin a route around the Dark Aether Nexus. You must stay near the orb killing all zombies that spawn to fill the orb with souls until it has reached the structure in the center of the area and entered inside it. Once the orb is inside the structure, interact with the orb to upgrade the Staff of Ice into Ull's Arrow.

Ull's Arrow Upgrade

During the route, the orb will spawn a mixture of regular zombies, Shock Mimics, Doppleghast, and even Amalgams. You must stay relatively close to the orb otherwise you will fail the step and have to re-try on the following round.

Step 3: Pass the Trials

Vermin Trial

With Ull's Arrow in hand, press the toggle fire button to switch to Sekhmet's Vigor to shoot a Healing Orb at the crystal on the Vermin Statue in the Dark Aether Nexus against a rock opposite the structure in the center, releasing its essence.

Vermin Statue in Dark Aether
Vermin Statue in Dark Aether

Interact with the crystal to pick up the essence and bring it to the Vermin Statue in the Dig Site (spawn room) where you can place it on the crystal in that statue, beginning a 60-second lockdown where you must kill a load of Vermin before it ends to refine the crystal.

Vermin Statue in Dig Site

A charged shot from Ull's Arrow will absolutely annihilate the Vermin making this lockdown a breeze (no pun intended).

Once refined, interact with the crystal to pick it up where you must return it back to the Vermin Statue in the Dark Aether Nexus without taking too much damage, as indicated by the Amulet Energy bar, however only one Gateway on the map will be open to the nexus which you must find.

The refined cystal cannot be picked up during a Special Round.

Parasite Trial

With Ull's Arrow in hand, press the toggle fire button to switch to Sekhmet's Vigor to shoot a Healing Orb at the crystal on the Parasite Statue in the Dark Aether Nexus against a rock opposite the structure in the center, right of the Vermin Statue, releasing its essence.

Parasite Statue in Dark Aether

Once refined, interact with the crystal to pick it up where you must return it back to the Parasite Statue in the Dark Aether Nexus without taking too much damage, as indicated by the Amulet Energy bar, however only one Gateway on the map will be open to the nexus which you must find.

The refined cystal cannot be picked up during a Special Round.

Doppleghast Trial

With Ull's Arrow in hand, press the toggle fire button to switch to Sekhmet's Vigor to shoot a Healing Orb at the crystal on the Doppleghast Statue in the Dark Aether Nexus against a rock right behind the structure in the center, releasing its essence.

Doppleghast Statue in Dark Aether

Just like the Vermin, a charged shot from Ull's Arrow will absolutely annihilate the Vermin making this lockdown also a breeze.

Once refined, interact with the crystal to pick it up where you must return it back to the Doppleghast Statue in the Dark Aether Nexus without taking too much damage, as indicated by the Amulet Energy bar, however only one Gateway on the map will be open to the nexus which you must find.

The refined cystal cannot be picked up during a Special Round.

Amalgam Trial

With Ull's Arrow in hand, press the toggle fire button to switch to Sekhmet's Vigor to shoot a Healing Orb at the crystal on the Amalgam Statue in the Dark Aether Nexus against a rock right behind the structure in the center, right of the Doppleghast Statue, releasing its essence.

Amalgam Statue in Dark Aether
Amalgam Statue in Dark Aether

Interact with the crystal to pick up the essence and bring it to the Amalgam Statue in the Deep Excavation where you can place it on the crystal in that statue, beginning a 90-second lockdown where you must kill an HVT Amalgam before it ends to refine the crystal.

Amalgam Statue in Deep Excavation

The Amalgam will become immune a certain points as indicated by a purple bubble around it, where it will be taking life from a Heavy Zombie in the area which you must kill to take down the bubble and be able to damage the Amalgam again.

Once refined, interact with the crystal to pick it up where you must return it back to the Amalgam Statue in the Dark Aether Nexus without taking too much damage, as indicated by the Amulet Energy bar, however only one Gateway on the map will be open to the nexus which you must find.

Step 4: Capture the Sentinel Artifact

You are about to enter the boss fight, it is highly recommended that you have at least a Legendary Tier 3 Pack-a-Punched LMG or AR, Tier 3 Armor, and all of your perks. The boss health does not scale with round, only the zombie health so take your time to get as geared as possible as this boss is extremely tanky.

The Sentinel Artifact is ONLY damageable via a bullet weapon. Wonder Weapons and other explosive weapons will not do any damage to the boss so make sure to put all your resources into upgrading your bullet weapon. Be sure to also take in a Mutant Injection for the final phase of the boss fight as that is by far the most difficult part.

Entering the Arena

Interact with the pedestal underneath the glowing archway to build a bridge to the boss arena. This will despawn all the zombies and will only respawn them continuing the rounds if you leave the Dark Aether Nexus or cross the bridge to the arena.

Once you are in the arena, interact with the Sentinel Artifact to start the final encounter in which you cannot return from.

Begin Boss Fight

Boss Attacks

The Sentinel Artifact is the boss of this map and only has one attack, that being a laser that emits from the front of the artifact as it spins around in a circle, simply avoid this laser by continuously rotating around the arena or by hiding behind the natural cover of the map underground.

Phase 1 Attack
Phase 1 Attack

Deeper in the fight, there will be multiple projections of the Sentinel Artifact which will also be in the center emitting lasers while rotating so you will need to avoid up to four lasers at a time.

Phase 3 Attacks
Phase 3 Attacks

Phase 1

During this phase, the Sentinel Artifact will be slowly rotating while emitting a laser. Zombies will spawn in the arena that you can kill with Ull's Arrow until the boss is damageable.

Phase 1 Attack
Phase 1 Attack

Once the Sentinel Artifact stops glowing orange it is damageable, shoot a charged shot of Ull's Arrow at your feet to protect you from zombies or activate while non-stop shooting the Sentinel Artifact with your bullet weapon until its shield breaks and it has multiplied into two Sentinel Artifacts.

Phase 1
Phase 1

If needed, be sure to use your to protect you while you do damage to the boss. If you fail to do enough damage, whatever statue the artifact was aiming at will be the load of enemies the artifact spawns in to try and take you out. This will either be, Vermin, Parasites, Dopplghasts, or Amalgams.

Phase 2

This phase is similar to Phase 1, this time with two lasers, one being emitted from each artifact. Repeat what you did for Phase 1 until the artifacts become damageable again.

Phase 2 Attacks
Phase 2 Attacks

If you are having trouble staying alive hording the zombies, you can camp underground with the Ull's Arrow use charged shots to stay alive, as long as you make sure you have some ammo for the damage phase or you should be fine.

Once they are damageable, shoot another charged Ull's Arrow shot or activate and focus fire on one artifact at a time until it breaks and multiplies then switch focus to the other until it breaks and also multiplies.

Phase 2
Phase 2

Phase 3

This phase is similar to the other phases, this time with four lasers being emitted, one from each artifact. At this point is highly recommended to camp underground with the Ull's Arrow until the artifacts become damageable if you haven't been already.

Phase 3 Attacks
Phase 3 Attacks

Once they are damageable, shoot another charged Ull's Arrow shot or activate and focus fire on one artifact at a time until it breaks. Once broken you cannot damage the others and Doppleghast and Amalgams will begin to spawn which you should focus fire on to kill them quickly.

Phase 3
Phase 3

Once the Special and Elite zombies are killed, focus fire on the Heavy Zombie who will have an orange Sentinel Artifact on it, which once killed will drop it and you must focus your fire onto that Sentinel Artifact until it breaks.

Phase 3 Artifact Zombie
Phase 3 Artifact Zombie

If you fail, you will need to repeat this entire phase. Really take advantage of your Ull's Arrow charged shots to help you survive.

Phase 4

This phase continues immediately from when phase 3 ends spawning in new Amalgams and Doppleghasts this time with the Sentinel Artifact being inside one of the Doppleghast. Focus fire on the non-artifact special and elite zombies.

Phase 4 Artifact Zombie
Phase 4 Artifact Zombie

Stay away from the Sentinel Artifact zombie, as getting too close to them will damage you as if you were getting hit by the lasers which will down you if you are not careful.

Once the Special and Elite zombies are killed, focus fire on the Doppleghast who will have an orange Sentinel Artifact on it, which once killed will drop it and you must focus your fire onto that Sentinel Artifact until it breaks.

You must do all of this before the lasers finish a cycle, which takes around 60 seconds. If you fail, you will need to repeat this entire phase. Really take advantage of your Ull's Arrow charged shots to help you survive same as phase 3.

Phase 5

The same as phase 4, this time with the Sentinel Artifact zombie being a Shock Mimic. As before, focus your fire on the non-artifact special and elite zombies, then focus fire on the Shock Mimic and Sentinel Artifact until it breaks.

Phase 5 Artifact Zombie
Phase 5 Artifact Zombie

Phase 6

This is the final phase of the boss fight and is extremely intense, this phase spawns multiple special and elite enemies with transparent artifacts in them along with an HVT Amalgam with an orange sentinel artifact which you should focus on last.

Phase 6 Artifact Zombie
Phase 6 Artifact Zombie

It is highly recommended to use a Mutant Injection to take out all of the zombies except for the final HVT Amalgam with the orange artifact, however you should hit it enough to weaken it and then finish it off once out of the Mutant Injection so you can focus fire on the artifact.

Once you have taken out all the zombies, finish off the HVT Amalgam and focus fire on the sentinel artifact until it breaks. It will go back into the middle where all the Sentinel Artifact projections will look up toward a structure containing a single Sentinel Artifact.

Phase 6
Phase 6

You must put as much damage into this singled-out Sentinel Artifact as possible until you have destroyed it and the health bar is depleted, in a short timeframe otherwise there will be a wipe mechanic that will end your game.

At this point, it is unclear if you can survive this wipe mechanic using the Dying Wish augment from like in the Voyage of Despair boss fight.

Once you have put enough damage into the artifact it will be defeated and you can interact with the artifact in the center of the arena to trigger the ending cutscene.
