The Long-Ear Invitation stage in Arknights: Endfield is one of the more creative puzzles in the Delver of the Cryptic event. At first glance, it appears simple: follow a long-ear creature to the exit. However, players aiming for full rewards must complete the bonus objective, which requires locating and escorting all six long-ears safely to their hideouts.

This guide breaks down every step, including hidden paths, laser barriers, breakable walls, and switch mechanics, ensuring you secure every reward tied to the stage.

Stage Overview – What Makes Long-Ear Invitation Unique?

Unlike combat-heavy stages, Long-Ear Invitation focuses on:

• Tracking NPC movement patterns

• Solving environmental puzzles

• Using explosive barrels strategically

• Unlocking laser barriers

• Breaking hidden walls

Your primary objective is simple:

Follow one long-ear to the exit.

Your bonus objective:

Locate and guide all six long-ears to their respective hideouts.

Failing to track them carefully can result in missing rewards.

Starting Area – Three Long-Ears Appear

At the beginning of the stage, you’ll encounter three long-ears.

Here’s what happens:

• They scatter in different directions.

• One on the right quickly finds its hideout.

• The other two require manual tracking.

First Hideout (1/6)

The right-side long-ear reaches its destination almost immediately. Follow it briefly to secure your first completion.

Breakable Wall Section – Second Long-Ear

The second long-ear runs behind a breakable wall.

You’ll notice:

• An explosive barrel placed nearby.

• No alternative path forward.

How to Proceed:

1. Interact with the explosive barrel.

2. Aim at the cracked wall.

3. Detonate to open the hidden chamber.

Inside, the long-ear waits at its hideout.

That makes 2/6 completed.

Tracking the Third Long-Ear – Dead-End Strategy

Return to the remaining long-ear from the starting area.

At some point:

• It splits into two identical paths.

• Both appear to run in opposite directions.

This is where players often get confused.

Important Rule:

Continue following the original long-ear until it reaches a dead end.

Both long-ears will eventually stop moving. Once they do, retrace your path and proceed along the only available route.

This mechanic ensures you don’t skip the intended progression path.

Third Hideout Location

After navigating past the dead-end trick, you’ll spot a hideout visible from a distance.

Escort the long-ear carefully toward it.

Once it enters, you’ll secure 3/6 long-ears.

Laser Barrier Section – Three Switch Puzzle

Progressing forward, you’ll encounter:

• Three laser barriers blocking the path

• An explosive barrel nearby

• Multiple hidden switches

Switch Locations:

• One hidden behind crates near the lasers

• Two stacked vertically beyond the barrier

Solution:

1. Interact with the explosive barrel.

2. Carefully aim at each switch.

3. Trigger all three to disable the lasers.

Once unlocked, a nearby hideout becomes accessible.

Escort the long-ear to secure 4/6 completions.

Final Two Long-Ears – Split Path Challenge

After clearing the lasers, you’ll encounter the last two long-ears.

One:

• Escapes through a pipe (no immediate interaction possible).

The other:

• Enters a small facility to the left.

Follow the one entering the facility.

Small Facility Puzzle – Interior Laser Barrier

Before entering fully, interact with the external switch to disable part of the interior barrier.

Inside:

1. Move to the upper floor.

2. Locate an explosive barrel.

3. Aim at the switch positioned behind a laser grid.

4. Detonate to unlock the lower section.

Return downstairs to find the fifth long-ear hideout.

That brings you to 5/6 completed.

Final Breakable Wall – Sixth Long-Ear

You cannot proceed further unless you:

• Locate an explosive barrel outside the small facility.

• Use it to destroy another breakable wall.

Behind it, the final long-ear waits.

Escort it to its hideout to complete 6/6 long-ears and finish the bonus objective.

Combat & Gear Considerations

Although the stage is puzzle-oriented, upgraded weapons still help:

• Faster enemy clearing.

• Reduced interruption during escort.

• Smoother navigation through hazard zones.

If your damage feels underwhelming, consider upgrading through a professional Arknights Endfield Weapon level boost to maintain efficient progression during limited-time events.

Common Mistakes to Avoid

❌ Ignoring the bonus objective and exiting early
❌ Missing the hidden switch behind crates
❌ Forgetting to activate the exterior facility switch
❌ Overlooking breakable walls

Long-Ear Invitation rewards exploration and patience. Rushing often results in missed long-ears.

Tips for Efficient Completion

• Always scan for explosive barrels in each area.

• Follow long-ears fully until they stop moving.

• Double-check blocked paths for destructible walls.

• Disable lasers before escorting to avoid unnecessary backtracking.

Final Thoughts

Long-Ear Invitation may appear easy at first, but achieving full completion requires careful tracking, environmental awareness, and puzzle-solving precision.

By locating all six long-ears and clearing every barrier, you’ll maximize event rewards and progress smoothly through the Delver of the Cryptic stages.
