Skolopendra in Fisch is the major boss encounter introduced with Mariana’s Awakening, but it does not appear the moment you enter the Obsidian Trench. The current trigger is tied to repeated Veiled Charybdis catches inside the trench.
To awaken Skolopendra in Fisch, catch roughly four to six Veiled Charybdis. As you complete enough encounters, the crystals throughout the Obsidian Trench turn deep red. That visual change is your warning that the Skolopendra sequence is being triggered.
How to spawn Skolopendra in Fisch

- Unlock the Obsidian Trench through Mariana’s Awakening.
- Enter the trench and locate its river fishing areas.
- Fish until you hook a Veiled Charybdis encounter.
- Complete the special reeling minigame.
- Repeat the process and catch approximately four to six Veiled Charybdis.
- Watch the trench crystals for a change from their normal appearance to deep red.
- The red-crystal state signals that Skolopendra is awakening.
The reported four-to-six range means you should not leave after exactly four catches if nothing happens. Keep working through Veiled Charybdis encounters until the environment visibly changes.
Why are the crystals turning red?
The crystals act as the clearest environmental signal for Skolopendra in Fisch. White crystals normally help you deal with Trench Suppression, but after enough Veiled Charybdis catches the trench takes on the red-crystal state associated with the boss awakening.
If the crystals are still normal after several catches, keep fishing rather than assuming the server is broken. The trigger is not reported as one fixed guaranteed catch count.
How to catch Veiled Charybdis
Veiled Charybdis uses a special reeling sequence rather than a standard passive bestiary catch. Whirlpools appear during the encounter and can remove rod control, so pay attention to the hazard instead of staring only at the progress bar.
Our Veiled Charybdis guide covers the encounter separately. Those catches are the practical setup step for Skolopendra in Fisch.
What do you get for defeating Skolopendra?
Defeating Skolopendra is tied to conquering the Obsidian Trench and unlocking purchase access to the Chasm-Stalker Rod. The rod is the main equipment reward from the update, with a new mutation, unique passives and a streak system.
That makes the boss more than a one-off spectacle. Players working toward the Chasm-Stalker Rod need the boss progression as part of the unlock route.
Do you need to complete the bestiary first?
The boss trigger itself is tied to Veiled Charybdis rather than simply reaching 100% bestiary completion. However, the broader rod and trench-conquest progression also uses the area’s completion state, so defeating Skolopendra in Fisch does not make every remaining collection objective irrelevant.

How this fits into Mariana’s Awakening
The Skolopendra in Fisch progression is part of the September Mariana’s Awakening update, which sends players back through the existing Mariana’s Veil layers before opening the new Obsidian Trench. Keep your layer rods, bait and access routes ready because several of the new objectives deliberately reuse older Veil locations.
Once the five descendant gauntlets are complete, the quest continues through the Crevice Wall, five layer gems and the Abyss Gate. Inside the trench, Trench Suppression, Veiled Charybdis and Skolopendra become the next major systems to learn.
What to prepare before triggering Skolopendra
Before pushing the trench into its red-crystal state, clear enough space in your session to finish the boss sequence rather than triggering it while you are already struggling with suppression. Keep a nearby white crystal in mind, finish any inventory housekeeping first and make sure the account that needs the completion is the one actively progressing the encounter.
The Skolopendra in Fisch route sits late in Mariana’s Awakening, so losing track of your personal progression at this point can mean repeating several Veiled Charybdis catches. Treat the crystal colour change as the point to stop ordinary fishing and focus on the boss objective.
