How Do You Clear Delver of the Cryptic in Arknights: Endfield?

Delver of the Cryptic is the puzzle mode of Arknights: Endfield, and it is one of the easiest ways to collect extra Oroberyl without touching combat content. Each new Spatial Set adds a fresh batch of Protocol Spaces, and the newest one, Fade Beyond the Painting, opens on November 12, 2026. At gamemarket.gg, we explain how to unlock the mode, how Protocol Spaces work, what each spatial set rewards and when the new stages arrive. We update this guide every time a new spatial set is released.

What Is Delver of the Cryptic?

Delver of the Cryptic is a permanent puzzle mode that launched on February 24, 2026. Instead of fighting through stages, you enter short challenge maps called Protocol Spaces and solve them to reach the exit.

Protocol Spaces are grouped into Spatial Sets. Each set has its own theme and a fixed number of stages, and new sets are added over time. Older sets stay available after they launch, so you can clear them whenever you have time.

The stages focus on puzzles and movement rather than damage, so you do not need a strong roster to clear them. Patience matters far more than your Operators' levels.

How to Unlock and Open Delver of the Cryptic

• Requirement: finish the main mission Chapter I, Process II: Paving the Way
• Where to find it: open the Events menu and select Delver of the Cryptic, then pick a spatial set and press Enter
• Later sets: some locked spatial sets unlock as you progress further through the main story

Before entering a Protocol Space, check its reward panel. It shows how many Storage Crates are hidden in the stage and what the bonus objective is, which saves you a second run.

How Protocol Spaces Work

Every Protocol Space has three layers of rewards:

• First clear: reaching the exit for the first time gives the main reward, including Oroberyl
• Storage Crates: each stage hides crates along the route, usually three, with T-Creds and upgrade materials inside
• Bonus objective: an extra condition, such as clearing the stage within a time limit, for more materials

Clearing every Protocol Space in a set awards that set's engraved medal. If you also finish every bonus objective and open every Storage Crate in a stage, that stage counts as a perfect completion, and perfect completion across the whole set upgrades the medal.

New sets are usually time-gated. Only part of the set is available on launch day, and the rest opens on a later date.

Fade Beyond the Painting: The Newest Spatial Set

Fade Beyond the Painting is the fourth spatial set, and it arrives during the second phase of the Sanctuary of Ink version. According to the official update notes, it opens in two parts:

• Part 1: November 12, 2026, at 12:00 server time, with 3 Protocol Spaces
• Part 2: November 19, 2026, at 04:00 server time, with 3 more Protocol Spaces

Endfield uses UTC+8 as server time on the Asia server and UTC-5 on the Americas and Europe server, so Part 1 opens at 11:00 WIB on the Asia server.

Clearing the spatial set challenges rewards Oroberyl x1,200 and Mark of Perseverance, along with the usual stage materials. Like the earlier sets, Fade Beyond the Painting has six stages in total. We will add the stage names and short tips for each Protocol Space once both parts are live.

Every Spatial Set So Far

What Delver of the Cryptic Rewards

A first clear of a Protocol Space typically gives:

• Oroberyl x200
• T-Creds x20,000
• Advanced Cognitive Carriers
• Protohedrons
• Mark of Perseverance x1
• Arms INSP Sets

Storage Crates and bonus objectives add more T-Creds, Cognitive Carriers, Protohedrons and Arms INSP Kits, but no extra Oroberyl. That means the Oroberyl in each set comes from first clears, so a six-stage set is worth 1,200 Oroberyl in total.

If you have never played the mode, clearing every older set is a quick boost to your pull budget before the next banner. Our Endfield codes guide lists other free sources of rewards that are still active.

Tips for Clearing Every Protocol Space

• Read the mechanics first. Each stage explains its main mechanic in the top right corner before you enter
• Check the crate count. Knowing how many Storage Crates a stage has stops you from finishing early and missing one
• Do the timed objectives on a second run. Learn the route first, then go back for the time limit
• Use checkpoints. In stages like Beam Dodger, touching a hazard sends you back to the nearest checkpoint instead of failing the run
• Adjust the camera. Many hazards, especially lasers, are easier to read from a higher angle
• Come back on unlock days. Time-gated stages only open on their release date, so check in again on November 19 for the second half of Fade Beyond the Painting

Fitting Delver Into Your Routine

Delver of the Cryptic does not reset, so it works best as a one-time task each time a new set arrives. Clear the first three stages of Fade Beyond the Painting on November 12, finish the last three after November 19, and fit them around your regular dailies. Our daily and weekly routine guide shows how to plan the rest of your week, and our Contingency Contract guide covers the endgame mode that does need a strong team.

If you want a stronger roster without the grind, you can explore trusted Arknights: Endfield Accounts, keep your dailies and events on track with reliable Arknights: Endfield Hourly Services, or clear tough content faster through dependable Arknights: Endfield Boosting.
