By the time you reach Chapter 3: Chasm of Xal’Goroth in the Revelations DLC, the game starts asking much more from you. The combat encounters become larger, platforming sections are more involved, and several secrets are tucked away behind optional puzzles that are easy to miss if you’re only following the main objective.
This chapter also introduces plenty of worthwhile rewards, including Relic Pieces, Leader Essence, a Life Sigil, a Toy Collectible, several Platinum caches, and the Yellow Eldritch Key used to unlock optional areas.
If you’re aiming for 100% completion, this walkthrough covers every collectible and secret you’ll encounter along the way.
Doom The Dark Ages Revelations Chasm of Xal’Goroth Secrets Guide
Your primary objective in this chapter is:
- Seek the 2nd Ascension Stone
While progressing toward the Ascension Stone, you’ll have several opportunities to explore side paths containing optional rewards.
Chasm of Xal’Goroth Collectibles
Before diving into the walkthrough, here’s everything you can collect during Chapter 3.
| Collectible | Total |
|---|---|
| Toy | 1 |
| Life Sigil | 1 |
| Platinum | 6 |
| Yellow Eldritch Key | 1 |
| Hollow Shrines | 2 |
| Leader Essence | 1 |
| Relic Pieces | Multiple |
Reach the First Hollow Shrine
Not long after progressing through the level, you’ll eventually arrive at the entrance leading toward Labyrinth’s End.
Before heading inside, look around carefully.
You’ll find a Hollow Shrine positioned directly beside the entrance.
Since Hollow Shrines allow you to purchase Suit Upgrades, it’s worth stopping here if you’ve collected enough Leader Essence Shards during earlier chapters.
Secret Relic Piece #1
Don’t rush through the doorway just yet.
Face the entrance to Labyrinth’s End and look toward the left corner.
A hidden Relic Piece is tucked away nearby.
It’s an easy collectible to overlook because the main path naturally draws your attention toward the doorway.
Secret Relic Piece #2
Now turn toward the stone structures sitting on the right side of the Hollow Shrine.
Climb onto the elevated rocks and jump across to the nearby stone platform.
Another hidden Relic Piece waits here.
Missing this jump means missing one of the chapter’s earliest secrets.
Continue Until the Energy Node Chamber
Keep following the main objective until you enter a large chamber featuring:
- A floating blue Energy Node
- A large suspended sphere
- Rotating platforms
- Rising lifts
This room contains the majority of Chapter 3’s collectibles.
You’ll also discover another Hollow Shrine here, making it a good opportunity to spend any newly acquired Leader Essence Shards before continuing.
Collect the Platinum Trail
Look for the rising platform carrying a movable cube.
Ride the platform upward.
As it reaches its highest point, quickly jump across to the elevated platform ahead.
You’ll discover:
- A Platinum Trail
- A Yellow Gate
Follow the trail to collect your Platinum.
Relic Piece Along the Trail
Continue following the same elevated path.
At the end of the Platinum Trail you’ll find another Relic Piece waiting for you.
Since it’s directly along the route, it’s almost impossible to miss once you’ve reached this platform.
Relic Piece Across the Rotating Bridge
This puzzle is one of the chapter’s more interesting secrets.
Move the cube carrying the Blue Energy Node onto one side of the rotating bridge.
Rotate the bridge so the cube ends up opposite the location where you previously found the second Angel Relic.
Once everything is lined up:
- Activate the Energy Node.
- Allow the bridge to extend.
- Cross the newly created path.
A Relic Piece sits near the right edge of the platform beyond the bridge.
Secret Relic Piece Above the Left Lift
Return to the central room.
This time, instead of taking the same lift as before, ride the left-hand rising platform.
At the top you’ll discover another hidden Relic Piece.
It’s a quick detour that’s easy to miss if you only focus on progressing forward.
Hidden Room Secret
One of the best secrets in the chapter requires paying attention to your surroundings.
Look toward the ceiling for an orange Shield Target.
Throw your Shield Saw to hit it.
Doing so causes a hidden doorway to open.
Inside you’ll find several rewards grouped together:
- Secret Relic Piece
- Platinum
- Life Sigil
This is easily one of the most valuable hidden rooms in Chapter 3, so don’t skip it.
Defeat the Miniboss
Near the second Angel Relic area you’ll find a doorway leading into a large combat arena.
Prepare for a lengthy fight against:
- Large demon waves
- A miniboss encounter
After clearing every enemy, you’ll receive Leader Essence.
Besides progressing your Suit Upgrades, this is one of the most rewarding battles in the chapter.
Obtain the Yellow Eldritch Key
After defeating the miniboss, locate the nearby green portal launcher.
Use it to launch yourself toward the next platform.
Here you’ll find the Yellow Eldritch Key.
This key unlocks several optional paths containing additional collectibles.
Platinum Near the Yellow Gate
Before leaving the area, head left from the platform where you collected the key.
You’ll find a Yellow Gate protecting a Platinum cache.
Open it using the Yellow Eldritch Key to collect the nearby Platinum rewards.
Platinum Trail #2
With the Yellow Key in your inventory, return to the earlier platform containing the Angel Relic Pieces.
Open the locked Yellow Door on the left.
Inside you’ll discover another Platinum Trail.
Follow the trail completely to collect every Platinum pickup.
Archvile Toy Location
Immediately after finishing the second Platinum Trail, don’t continue straight ahead.
Instead, look for the series of green Chain Spear grapple points suspended over the gap.
Swing across them carefully.
One of the platforms along this route contains the chapter’s only Toy Collectible.
If you’re collecting every Toy in the DLC, this is the one to grab before moving on.
Final Platinum Collectible
Continue using the Chain Spear grapple points after collecting the Toy.
The final platform contains another Platinum Trail positioned beside another Yellow Gate.
Collect every Platinum pickup before returning to the main route toward the chapter’s conclusion.
Chasm of Xal’Goroth is one of the more exploration-heavy chapters in the Revelations DLC. While the main objective—finding the second Ascension Stone—is fairly straightforward, nearly all of the chapter’s best rewards are tucked behind optional platforming routes, Shield Saw puzzles, and key-locked areas.
