What Is the Chasm-Stalker Rod?
Chasm-Stalker is the endgame rod tied to the new Obsidian Trench, the area buried beneath Mariana’s Veil. It looks like a segmented black-and-red centipede with hooked limbs and glowing orange eyes, and it’s not a random drop — you have to earn it through a full questline, a trench Bestiary, and a boss fight.
Chasm-Stalker Rod Stats
The rod’s passive is a whirlpool mechanic: every 4 seconds there’s a 50% chance it summons a whirlpool during the reeling minigame that pulls fish in and speeds up their forced progress, while gradually cutting your control. It also grants catches a roughly 35% chance at the Myriapodic mutation, and it has its own Perfect Streak counter separate from your normal streak. Equipping it also removes the Trench Suppression penalty that otherwise slows your lure speed down here — a solid reason to grind for it even before you’ve filled the Bestiary.
How to Unlock the Chasm-Stalker Rod?
Step 1: Start Vaelor’s Questline at Roslit Bay
Find Vaelor on the Roslit Bay shoreline (around -1415, 134, 482). His first stage, Chart the Veil, just wants you to discover all of Mariana’s Veil. After that, Worthy of the Abyss sends you to his five descendants.
Step 2: Complete the Five Descendant Quests
Each descendant wants regional catches with a specific rod:
- Ignis (Volcanic Vents): Volcanic Rod — perfect catch 2 Charred Coelacanth, catch 1 Obsidian-Plated Piranha
- Glacius (Challenger’s Deep): Challenger’s Rod — catch 3 Hoarfrost Halibut, perfect catch 1 Glacial Gulper
- Tenebris (Abyssal Zenith): Rod of The Zenith — catch 2 Lumin-Lure Lanternfish, perfect catch 1 Void-Drifter Jelly
- Luminis (Calm Zone): Ethereal Prism Rod with Seaweed bait — catch 4 Geode Grouper, perfect catch 2 Pearl-Plated Pleco
- Resonus (Veil of the Forsaken): Leviathan’s Fang Rod (350,000 C$) — perfect catch 5 Gargoyle Goby, 3 Wraith-Whisper Ray
Finishing all five gives you the combined Mariana’s Gauntlets.
Step 3: Solve the Obsidian Threshold Riddle and Open the Abyss Gate
Head back to Vaelor for Into the Void — you need to perfect catch a Scylla (regular catches don’t count). Scylla Hunts run for 15 minutes and only one player can land the catch, so keep an eye out or trigger one with a Sundial Totem.
After that, jump into the central abyss to reach Obsidian Pocket, where you’ll get a personal riddle at the Crevice Wall. The pairings are Ashen→Volcanic Rod, Chilled→Challenger’s Rod, Wrath→Rod of The Zenith, and Prismize→Ethereal Prism Rod. Catch a Scylla with the matching mutation (doesn’t need to be perfect this time) and present it at the altar to open the Abyss Gate.
Step 4: Clear the Obsidian Trench Bestiary
The trench Bestiary has 12 entries — 10 are standard catches (Pumice Puffer, Scoria Scorpionfish, Ash-Cloud Angelfish, Obsidian Gaveltooth, Cinder-Crust Gar, Tectonic Toadfish, Basalt Behemoth, Magma-Glass Marlin, Shatter-Tooth Shark, and Shatterjaw Shark), and 2 are special encounters. Entering the trench triggers Trench Suppression, which slows your lure speed — use the glowing white crystals scattered around to Absorb temporary relief before fishing.
Step 5: Catch Veiled Charybdis and Defeat Skolopendra
Charybdis prefers Night with Meteor or Stag Beetle bait (Luminous Larva works as a backup). Watch the lower hazard meter closely — filling it kills you, so don’t get greedy. Landing roughly 4–6 Veiled Charybdis turns the trench crystals deep red and wakes Skolopendra, which you then fight through its own boss minigame using Kraken Tentacle bait during Rain.
Step 6: Buy the Chasm-Stalker Rod
Once the boss is down and your Bestiary reads 100%, head to the floating rod crystal on the shop pedestal at the center of Obsidian Trench, interact with it, pay 5,000,000 C$, and equip Chasm-Stalker.
Common Mistakes to Avoid
- Trying to jump into the abyss before perfect-catching the required Scylla — it won’t progress the quest
- Ignoring your personal riddle and grabbing the wrong Scylla mutation at the altar
- Letting the Veiled Charybdis hazard bar fill completely — it’s an instant kill
- Assuming Skolopendra spawns on a timer; it only wakes after enough Charybdis catches
