Limbus Company x Arknights Collab Guide: Pilgrimage of Compassion Rewards and Tips

Limbus Company is a story focused RPG that combines tactical battles with a dystopian journey across the City.

The Limbus Company Arknights collab, "Pilgrimage of Compassion," is the first crossover in Limbus Company's history, and it works unlike anything else in the game. Characters from Arknights walk into The City, a dimensional door opens over Iberia, and Project Moon and Hypergryph turn the whole thing into a story chapter, themed combat, and a set of E.G.O you can't get anywhere else.

If you're trying to work out what this Limbus Company x Arknights guide should cover, the key point is the structure: this event is built like a new Intervallo launch, with a story, an event shop, and a Mirror Dungeon theme pack. But it breaks one rule that changes how you should approach it.

What Pilgrimage of Compassion Actually Is

This is a one-way collaboration. It ran only in Limbus Company, and Arknights didn't host a matching event. Hai Mao, Arknights' vice president and head producer, explained on Bilibili that the collab was one-directional "due to various reasons." So don't expect to find Limbus content in Arknights later.

The event's story sits between Intervallo VI: Spring Cultivation and Canto IX: The Unsevering, and it opened with a PV introducing the dimensional door over Iberia. The premise is that something very distant, never before observed, is reaching through.

Mechanically, it mirrors a standard Intervallo event: a story chapter, themed E.G.O, an event shop, and a Mirror Dungeon theme pack. The twist is below, and it's the reason this guide leads with a warning.

The Warning: This Event's Story Is Gone

Here's the part that matters most for new players. Pilgrimage of Compassion was the first limited event in Limbus Company's history where, after the event ended, its combat events and story weren't added to the in-game Theater. The story was only accessible during the event period and was removed permanently afterward.

That means if you're reading this looking for the event in-game today, you won't find it. The associated E.G.O have likewise become completely unobtainable. This guide is a record of what the event offered and how it worked, useful whether you played it, missed it, or want to understand why the community still talks about it.

The E.G.O that were time-limited to this collab: the Tidal Elegy Ishmael E.G.O, available only as an event reward, and the Command: Meltdown Faust, To Remain Oneself Hong Lu, and Unbrilliant Glory Gregor E.G.O, obtainable only from the Pilgrimage of Compassion New E.G.O Extraction banner, never through the standard Dispenser. The Amiya Announcer, a cosmetic, came only from purchasing the Amiya Announcer Pack with Paid Lunacy during the event window.

How the Event Rewards Worked: Sea Terror Samples

The currency was Sea Terror Samples, and you earned them by playing the event's stages and dungeons.

Clear event-exclusive stages and dungeons for Sea Terror Samples, with a first-clear bonus on each stage.
Farm the final stage, a repeatable dungeon with a much higher Enkephalin-to-Sample ratio than the rest.
Play older Main Story stages and dungeons for the first time to earn Samples scaled to your Enkephalin use.
Clear Mirror Dungeon floors: 10 Samples per floor on normal, 20 on Hard.
Pick the "Pilgrimage of Compassion" theme pack on Floors 4 and 5 of Mirror of Immortality on Hard difficulty for extra Samples, 50 for a clear and 100 more on Hard.

There was a community-friendly detail worth remembering: having event Identities and E.G.O in your team loadout boosted Sample earnings by 40%, even when those units weren't directly fighting. The boost stacked, and it maxed at 120%. A rare 5% drop of a Luminous Sea Terror Sample auto-converted to 20 Samples.

Step Guide: What to Prioritize in the Reward Exchange

The Limbus arknights collab rewards lived in the Reward Exchange, which ran for five weeks, from September 25 to October 30, 2025. That gave a grace period after the event itself closed. Fully clearing it required 5,050 Sea Terror Samples.

1. Buy the Tidal Elegy Ishmael E.G.O first at 1,000 Samples. It's the only way to get it.

2. Grab the Special Decoration Style at 750 and the Special Banner at 600 if you collect cosmetics.

3. Pick up the standard Decoration Style and Banner at 250 and 200.

4. Spend leftovers on Enkephalin Boxes, Extraction Tickets, and Egoshard Crates.

5. Skip nothing that's event-exclusive, because these items never returned.

The math is unforgiving. 5,050 Samples across a five-week exchange means steady play, and players who waited until the final days found themselves short. Front-loading the repeatable dungeon was the efficient path. If you were chasing the full set of collab rewards, the event shop was where most of your Sea Terror Samples went, and the exclusive E.G.O sat at the top of that list.

Why Players Still Bring This Up

Pilgrimage of Compassion tripled Limbus Company's player count overnight and pushed the game to an all-time peak. A crossover that pulls numbers like that from a fanbase as devoted as Arknights' makes sense, and it set the template for how Project Moon handles limited collabs going forward.

The deeper reason it lingers is that permanent loss. E.G.O you can never obtain, a story you can never rewatch in-game, a fight that no longer exists. Limbus Company fans used to the Theater preserving everything learned the hard way that a collab could be truly temporary.

If You Missed It

There's no legitimate way back into the Pilgrimage of Compassion E.G.O now that the event's gone, but the game itself is still worth playing. Limbus Company continues with new Intervallos and story chapters, and the community keeps a detailed wiki record of the collab for anyone curious about what it contained.

For collectors, the lesson is to treat Limbus limited events as genuinely limited. Clear the story, buy the exclusive E.G.O, and finish the exchange while the window is open, because there's no rerun safety net.

A note on getting back in, since the event itself is closed. If you're returning after a break, install Limbus Company from a trusted source and keep your account linked, so a device change doesn't cost you progress you already earned. Keep Google Play Protect enabled and check the permissions the app requests on install, which for a single-player RPG should stay minimal.

The Takeaway on the Limbus Company x Arknights Collab

Pilgrimage of Compassion is a history lesson as much as a game event. It shows what a Project Moon crossover looks like, and it established that Limbus limited content can vanish for good. If you were there, you know why it's still discussed. If you weren't, you now know what you missed and why the community treats every new limited event with more urgency.

Limbus Company on Android from APKPure is still the place to follow Project Moon's ongoing story, even without the Arknights crossover available. If a future collab lands, take this guide as your warning: clear it while the door is open, because the door doesn't reopen.
