The Ashclaw is a Cataclysmic catch in Fisch that only appears inside Roslit Volcano during an eruption. It spawns in the lava near the central pillar and punishes underprepared loadouts with an extreme -95% progress speed and -70 resilience on hook. If you’re targeting it for the XP and payout, you’ll need the right timing, a rod that can fish in lava, and a setup tuned for stability.

Find Ashclaw (Roslit Volcano eruption)

Head to Roslit Volcano and wait for the eruption event. When the eruption is active, move to the center of the lava pool near the main pillar. Players can use in-game coordinates to position precisely at -1945, 275, 230.

There are no time-of-day, weather, or season requirements. Ashclaw is available only during the eruption window and only inside the volcano’s lava.

Improve your chances of an eruption

The eruption triggers naturally on its own cadence. Totems do not speed it up. Community fishing activity in the volcano helps—more players fishing there increases the odds the event fires. If you’re coordinating with friends, stack your time in Roslit to avoid long solo waits.

Use a lava‑safe rod (and smart enchants)

You can only fish Ashclaw from inside the lava, so your rod must support volcanic fishing. The following work:

  • Magma Rod
  • Reinforced Rod
  • Onirifalx
  • Volcanic Rod
  • Any fishing rod with the Invincible enchantment

For consistency once hooked, high-tier options like Ruinous Oath, Luminescent Oath, or Seraphic perform well. Build around resilience and progress speed support; Ashclaw’s penalties are severe. The Steady enchantment and the Tempest Rod passive do not mitigate Ashclaw’s progress speed debuff, so prioritize other enchants that boost your baseline reeling performance. Blessed Song is a strong pick if you have it.

Best bait and conditions

Ashclaw prefers Coal bait. There are no weather, time, or season modifiers to chase, so keep Coal slotted and focus on eruption uptime and mechanical execution. If you’re optimizing for pull rate, pairing Ruinous Oath with a Beached Pearl is a reliable combination.

What changes in the fight

  • On hook, Ashclaw applies -95% progress speed and -70 resilience, making the reel far slower and less forgiving.
  • It moves erratically across the bar, so prioritize control over raw speed.
  • You’ll see an exclamation point above your character and hear a unique chime when it bites—standard cues for Cataclysmic fish.

Given the progress penalty, lean on enchants and rods that raise baseline reeling rather than passives that specifically target progress-speed reduction. Keep tension tighter than usual to offset the low resilience and avoid panic surges when the bar darts.

Rod passives and exceptions that matter

  • Rod of the Depths passive effects do not work on Cataclysmic fish, including Ashclaw.
  • Rod of the Forgotten Fang generally won’t apply passive catches here either; however, if you trigger its Megalodon passive reel on an Ashclaw, the Megalodon effect will duplicate the Ashclaw instead of replacing it.
  • Steady and the Tempest Rod passive don’t bypass Ashclaw’s progress-speed penalty.

Summary: catch Ashclaw efficiently

  1. Travel to Roslit Volcano and set up near the center pillar over the lava.
  2. Wait for an eruption. Fishing with other players in the area can help the event occur more quickly.
  3. Equip a lava‑safe rod (Magma, Reinforced, Onirifalx, Volcanic, or any Invincible‑enchanted rod). Favor high-tier rods like Ruinous Oath, Luminescent Oath, or Seraphic.
  4. Slot Coal bait. For pull probability, Ruinous Oath plus a Beached Pearl is a strong option.
  5. Prepare enchants for baseline reeling gains (e.g., Blessed Song) and resilience; don’t rely on Steady or Tempest to counter the progress penalty.
  6. On hook, expect slow progress and sharp bar movement; keep tension steady, prioritize control, and ride out the slow reel.

If you treat Ashclaw like any other rare pull, it will punish you. Treat it like a boss: wait for the eruption, fish directly in the lava at the center pillar, run a lava‑safe, high‑tier rod with Coal, and build for control over speed. With the right setup and a little patience, the slow reel pays out big.
