Main Quest Video Guide
Step 1-2
Pack-A-Punch & the Ice Staff Parts
Enter the Dark Aether Nexus to unlock Pack-A-Punch.
Obtain the 3 Ice Staff Parts: Monocle, Staff, and Head Piece (see below for details on each).
Monocle (must be picked up first):
- Dropped from the first Shock Mimic killed.
Staff Part
The Staff — Tombs Area
Shoot Purple Lamps around the Tombs area to move the Purple Fire between lamps until it sits above the Bull Mural and symbols appear on the mural.
Shoot the symbols in order from 1 to 8 — they resemble Roman numerals.
After all symbols are shot, a lockdown starts.
After the lockdown completes, pick up the Staff piece.
Staff Part
The Head Piece — Neolithic Catacombs
Shoot Purple Lamps around the Neolithic Catacombs to move the Purple Fire between lamps until it sits above the Orion Mural and symbols appear on the mural.
Shoot the symbols in order from 1 to 10 — they resemble Roman numerals.
After all symbols are shot, a lockdown starts.
After the lockdown completes, pick up the Head Piece.
Step 3
Monolith Defense
Place the parts on the Monolith in the Dark Aether Nexus to start a defensive lockdown.
Defend the Staff of Ice from purple zombies trying to attack it.
After the lockdown completes, pick up the Staff of Ice from the Monolith.
Upgrade
Ull's Arrow Upgrade
Freeze 3 of the same Purple Lanterns (from the Staff or Head Piece steps) using the Staff of Ice, freezing all 3 within 10 seconds.
In the Dark Aether Nexus, shoot 3 purple symbols on floating rocks to lower them. Note these symbols down.
After shooting the 3 symbols, one of the 4 portals will close. Go to the other side of that portal in the overworld — a wall of symbols will be there.
Shoot the same 3 symbols (in the same order they were on the rocks) using the Staff of Ice to open the portal.
Go through the portal and follow the purple orb. Get kills near it to charge it. Once it enters the Monolith, interact with it to upgrade your Staff of Ice.
Tip — Multiple Players
If multiple players have a Staff of Ice, others can upgrade theirs by grabbing a Monolith Crystal Shard near the Monolith and then interacting with the Monolith using their Staff of Ice.
Tip
If you fail the lantern step, shoot the frozen lanterns to break and respawn them.
Step 4-6
The 4 Vermin Statues
Use the revive shot from the Staff of Ice on the Crystal on the Vermin Statue in the Dark Aether Nexus, then interact with it.
Interact with the Vermin Statue in the Dig Site to start a lockdown.
After the lockdown, interact with the Statue again to pick up the item, then place it back into the Vermin Statue in the Dark Aether. You can only be hit 3 times, and only one portal will be open.
Repeat this for the other 3 statues (4 total) in the Dark Aether, in the following order. Each statue has a slightly different challenge:
- Vermin — Dig Site: Kill the Vermin.
- Parasite — Shrine of Hierophants: Kill Parasites and pick up the purple orbs they drop, bringing them one by one to the statue.
- Doppelghast — Ossuary: Kill the Doppelghasts.
- Amalgam — Subterranean Temple: Kill the Elite Amalgam.
Step 7
Boss Fight Setup
After the 4th statue is completed, interact with the stone below where the giant laser is pointing to open the bridge.
Cross the bridge and interact with the Sentinel Artifact to start the boss fight.
Recommended Loadout
It's highly recommended for everyone to have a Pack-A-Punch level 3, Legendary rarity weapon for this boss fight. Explosives and the Staff of Ice will not deal damage to the boss.
Final Steps
Boss Fight
This boss fight consists of 3 main phases. The phases get more difficult as you progress, with the final one having a wipe mechanic.
The Sentinel Artifact shoots a red laser that can damage you, flies up and back down. After it returns, it flies up once more and shoots a purple laser into a statue of an enemy type.
During this, everyone shoots the Sentinel Artifact to deal enough damage and chunk its health. Repeat until you enter Phase 2.
After each chunk of damage, a Max Ammo spawns on the middle pedestal — it doesn't last forever, so pick it up.
After each chunk of damage, another Sentinel Artifact joins the fight, also shooting lasers.
Tip
You can shoot multiple Sentinel Artifacts at once and chunk health multiple times in one interaction to skip additional interactions.
A Sentinel Artifact becomes attached to a zombie (eventually a Doppelghast and an Amalgam). Kill that zombie to make it drop the Sentinel Artifact, then shoot it before it flies back to the pedestal.
Repeat until you enter Phase 3.
The Sentinel Artifact enemy deals extra damage and can down you in one hit.
After each chunk of damage, a Max Ammo spawns on the middle pedestal — it doesn't last forever, so pick it up.
The Sentinel Artifacts fire a beam at a single Sentinel Artifact up on a wall — shoot it to lower its health until it's "dead".
If you don't deal enough damage during this phase, a wipe phase begins that downs everyone — make sure you're dealing enough damage.
Once the phase ends, interact with the Sentinel Artifact at the pedestal to complete the Main Quest.
