What to know
- The mission has two parts: finishing the slug-catching requirement and then powering the Electric Nexus.
- Progress can look stuck if the next checkpoint does not trigger after the first capture.
- The Electric Nexus activation is solved by extending a power connection across the area until the Nexus receives electricity.
- This plays like a short route/interaction objective rather than a long quest chain.
In Arknights: Endfield, this objective can feel inconsistent because the slug captures and the Electric Nexus power-up behave like separate checkpoints, so one can be done while the other still blocks completion.

Reference table for the mission flow
| Stage | What to do | What “done” looks like |
|---|---|---|
| Start the request | Accept Oleg’s request to catch his Originium Slugs. | The mission tracker shows the slug-catching objective. |
| Catch all slugs | Find and capture each required Originium Slug tied to the objective. | The tracker completes the “catch all slugs” requirement (or prompts the next step). |
| Turn on Electric Nexus | Supply power to the Electric Nexus by connecting it to an active electrical network. | The Nexus becomes powered/active and the mission completes. |
Where progress commonly breaks and how to fix it
If additional slugs do not progress or cannot be interacted with after catching the first one, returning to the quest giver can be required to force the next checkpoint. If interactions stop working or the objective count does not change, go back to Oleg after the first capture, then continue to the other slugs.
How to catch all Originium Slugs reliably
Catching slugs is best handled as a repeatable loop: locate the target, engage as needed, and complete the capture interaction until the objective count is fulfilled. If a slug appears “done” but the counter does not move, treat it as a progression/checkpoint issue rather than a combat problem and try the return-to-quest-giver fix.
How to turn on the Electric Nexus
The Electric Nexus step is about delivering electricity, not just reaching the device. A reliable approach is extending electricity across the area by placing/connecting power infrastructure repeatedly until the route reaches the Nexus and it receives power.
How to complete the mission
Step 1

Accept Oleg’s request and confirm the tracker shows the Originium Slugs objective.
Step 2

Capture the first Originium Slug and confirm the mission tracker updates.
Step 3

If the remaining slugs do not progress or cannot be interacted with, return to Oleg to trigger the next checkpoint, then resume capturing the remaining slugs.
Step 4

Continue until the objective to catch all required Originium Slugs is satisfied.
Step 5

Locate the Electric Nexus and begin extending a continuous electrical connection from a powered source toward the Nexus.
Step 6

Keep extending the electricity route until it successfully reaches the Electric Nexus and the Nexus turns on (mission completion condition).

Completing “Help Oleg catch all his Originium Slugs” cleanly
Treat the quest as a checkpointed sequence: finish the slug captures in a way the tracker recognizes, then focus entirely on powering the Electric Nexus by building an uninterrupted electricity connection to it.
