The Ashclaw is one of the rarest and most intimidating Cataclysmic fish in Fisch. Found deep within Roslit Volcano, this molten crab requires precision, patience, and the right setup to catch successfully. Below is a complete step-by-step guide explaining how to locate, spawn, and catch the Ashclaw efficiently — including its stats, bait preferences, and rod recommendations.
Fisch Ashclaw Guide – How to Catch, Spawns & Recommended Setup
Rarity: Cataclysmic (Luck-Favoring)
Region: Roslit Volcano (Roslit Bay)
Resilience: -70 (Extreme)
Progress Speed: -95% (Locked)
Preferred Bait: Coal
XP: 640,000
Average Weight: 350,000 kg
Average Value: 224,000 C$
Event Trigger: Volcano Eruption
The Ashclaw only appears during volcanic eruptions inside Roslit Volcano — it will not spawn under any other condition.
1. How the Ashclaw Spawns
Ashclaw’s spawn system is tied directly to natural world events. Here’s how it works:
It spawns only during an eruption inside Roslit Volcano at Roslit Bay.
Eruptions are randomly triggered, but their chance increases with the number of players fishing inside the volcano.
You’ll receive an on-screen notification when it begins:
“The Roslit Volcano has erupted!”
Once this message appears, head immediately inside the volcano. The Ashclaw will spawn visually within the lava area — large and unmistakable.
It’s not affected by weather, time of day, or season. You can farm it any time as long as the volcano erupts.
2. Recommended Setup
Catching the Ashclaw is extremely difficult — it has -95% progress speed and -70 resilience, meaning it resists almost every pull. Use the following setup for your best chance of success:
Bait
Coal (Required) – The only bait that the Ashclaw responds to.
Keep at least 20–30 pieces ready per eruption attempt.
Avoid using Meteor or Stag Beetle — those are for oceanic Cataclysmics, not the Ashclaw.
Best Rods for Catching Ashclaw
These rods provide strong Control and Lure Speed, helping counter the Ashclaw’s extreme resistance.
| Recommended Rod | Why It Works |
|---|---|
| Seraphic Rod | High control, reliable catch rate against Cataclysmics. |
| No-Life Rod | Excellent resilience handling and consistent pull power. |
| Cerulean Fang Rod | Balanced stats and control for steady catching. |
| Wicked Fang Rod | One of the strongest for fast tension recovery. |
| Rod of the Forgotten Fang | Can duplicate Ashclaw via its Megalodon passive reel (rare exception). |
Note: Passive-effect rods like the Rod of the Depths do not work for Ashclaw, except for the Forgotten Fang’s Megalodon Passive as a unique duplication case.
Additional Boosts
- Server Luck: Set to 1 or higher (private server boost helps).
- Aurora Borealis: Slightly improves Cataclysmic catch consistency.
- Ruinous Oath Enchantment: Recommended by the community for Cataclysmics.
3. The Catching Process
Join a server and travel to Roslit Bay.
Enter the volcano area and begin fishing with Coal bait equipped.
Encourage other players to join — more players fishing increases eruption chance.
Wait for the global message:
“The Roslit Volcano has erupted!”
Immediately move into the lava zone — Ashclaw will spawn visually.
Cast your line quickly. You only have a short window before the event ends.
Maintain steady control on your reel — Ashclaw has slow progress but can easily snap the line if mishandled.
4. Catch Behavior and Tips
Progress Speed: Extremely slow (takes longer than most Cataclysmics).
Control: Even high-control rods will struggle — stay focused.
Visual Cue: Emits ember-like particles while being reeled in.
Sound Cue: Plays a distinctive eruption-like sound when caught.
Broadcast: Once caught, your success is announced to the entire server with:
“[Player] captured the Ashclaw!”
5. What You’ll Earn

Catching the Ashclaw is not about speed — it’s about patience and coordination. Join an active server or bring friends to boost eruption rates, and keep your Coal stocked. Once the volcano erupts, react fast and stay calm through the slow reel.
