How to Catch Panthalus in Palworld 1.0: Location, Echoing Flute & Echobone Guide
- To catch Panthalus you need two things: the quest unlocked (beat the eighth tower boss, Auri & Shaolong on Sunreach, Lv 68) and the Echoing Flute — crafted from four Echobones plus the Faded Schematic. Then you summon and catch it at the Deserted Islet shrine.
- The four Echobones — Marine (122, −525), Seafoam (−519, −548), Silent (356, −110) and Tidewind (−262, 485) — sit at whale skeletons spread across the whole island, and the Researcher marks all four when you start the quest. Ignore guides using names like “Crashing Wave”; the in-game bones are Marine, Silent, Seafoam and Tidewind.
- Craft the Echoing Flute at ANY workbench (even a Primitive one — you do not need an “Ancient Workshop”), then play it at the Deserted Islet shrine to summon the Level 70 Panthalus. It’s Water-type, roughly 350,000 HP, and weak to Electric (Beakon is a strong counter).
- The biggest trap: CATCH it, don’t kill it. The fight scripts it down to a sliver where any Pal Sphere is a guaranteed catch — but if it dies you redo the whole fight, and you need the captured Panthalus in your active party to drop the World Tree barrier. (Bonus: Panthalus is also one of the fastest flying mounts in the game.)
Panthalus is the giant whale Pal that unlocks Palworld 1.0’s finale — you have to catch it to drop the World Tree barrier. It doesn’t spawn in the open world, so you can’t just go find it: you craft a special flute from four bones scattered across the island, summon the whale at a specific shrine, and capture it (killing it means starting over). Here’s the whole chain — every Echobone location with coordinates, the flute recipe, and exactly how the fight works.
Everything you need to catch Panthalus
Catching Panthalus has two independent requirements that come together at the Deserted Islet: you need the quest unlocked (which happens after the last tower boss) and the Echoing Flute (which you build from four Echobones plus a schematic). Here’s how it all stacks up:
| What you need | Where it comes from |
|---|---|
| Quest unlocked | Beat the 8th tower boss (Auri & Shaolong, Sunreach, Lv 68), then talk to Auri again |
| Faded Schematic | The Ancient Civilization Researcher on the Deserted Islet (unlocks the flute recipe) |
| 4 Echobones | Whale skeletons across the map (one Marine, Silent, Seafoam, Tidewind each) |
| Echoing Flute | Craft from the four Echobones at any workbench |
| The catch itself | Play the flute at the Deserted Islet shrine, then capture the Lv 70 Panthalus |
Step 1: Unlock the quest
The Panthalus quest only opens once you’ve cleared the game’s main tower ladder. The eighth and final tower boss — Auri & Shaolong, atop the new Sunreach sky islands (Level 68) — is the trigger: beat them, speak to Auri again to wrap the Sunreach story, and a marker drops on the Deserted Islet in the far south.
Travel there and speak to the Ancient Civilization Researcher by the fast-travel point. She hands you the Faded Schematic (which unlocks the Echoing Flute recipe) and marks the four whale-skeleton sites on your map.
Step 2: Collect the four Echobones
Each Echobone is a glowing bone at a giant-whale skeleton, and the four sites are spread right across the island — north to south, east to west:
| Echobone | Coordinates (X, Y) | Roughly where |
|---|---|---|
| Marine Echobone | (122, −525) | Skull west of the Hill of Beginnings (south-central) |
| Seafoam Echobone | (−519, −548) | Inside a skull east of the Eternal Pyre tower (volcanic SW) |
| Silent Echobone | (356, −110) | Near Mossanda Forest (east-central) |
| Tidewind Echobone | (−262, 485) | Near the Land of Absolute Zero (snowy north) |
A couple of honest notes: the Marine and Seafoam coordinates are confirmed by more than one source, but the Silent and Tidewind numbers (and the Deserted Islet’s exact figure) are single-source and differ slightly between guides — treat them as close, not surveyor-exact. And the in-game items really are the Marine, Silent, Seafoam and Tidewind Echobones: guides that list “Crashing Wave” or “Bubbling” bones are describing the same four skeletons with invented names.
Step 3: Craft the Echoing Flute
Once you have all four bones, combine them (one of each) into the Echoing Flute. The important part: it crafts at any workbench — even a Primitive Workbench works — so don’t waste time hunting for an “Ancient Workshop.” It’s a cheap craft; the whole cost is the four bones you just gathered.
Step 4: Summon and catch Panthalus
Return to the Deserted Islet and play the flute at the shrine beside the Researcher. A cutscene summons the Level 70 Panthalus — it exists nowhere else in the world, so this shrine is the only place you’ll ever fight it.
The fight itself:
- Panthalus is Water-type, with roughly 350,000 HP, and weak to Electric — Beakon is a strong, accessible counter.
- The encounter is scripted to knock it down to a sliver of HP where any Pal Sphere is a guaranteed catch. You do not need Legendary Spheres.
- Do not let it die. If Panthalus is killed, the entire summon-and-fight has to be repeated. Throw your sphere the moment its health locks at the low threshold.
What catching Panthalus unlocks: the World Tree
Panthalus isn’t just a trophy — it’s a key. Put the captured whale in your active party (the terminal checks your party, not your Palbox), travel to the World Tree barrier, and interact with the terminal. The cutscene plays, the barrier vanishes, and the endgame quest “The Sealed Calamity” begins.
Inside waits the finale: three Level 78 guardian bosses, then the typeless final boss Zenara & Astralym (Level 80, ~420,000 HP, no elemental weakness) — a pure gear-and-skill check. Beating it rolls the credits; there’s no New Game Plus, so you carry on in the same world afterward. (You’ll also want all eight tower Key Spheres for that final door — the Panthalus quest drops the outer barrier, but the tower path is a separate, parallel requirement.)
One happy bonus: the Panthalus you caught is one of the fastest flying mounts in the game (a ride-sprint of 3,000, second only to Jetragon), so it earns its party slot long after the barrier’s down — see our mount guide.
Common mistakes to avoid
- Don’t kill Panthalus. It’s a capture target. Whittle it down, then throw a sphere — killing it means redoing the whole encounter.
- Carry it in your active party. The World Tree terminal checks your party, not storage. Leave Panthalus in the Palbox and the barrier won’t budge.
- Use the right bones. The in-game items are the Marine, Silent, Seafoam and Tidewind Echobones. Other names are content-farm inventions for the same four sites.
- Any workbench works. A Primitive Workbench crafts the flute — no “Ancient Workshop” needed.
- Bring Electric. Panthalus’s Electric weakness turns a 350k-HP slog into a manageable fight; going in with the wrong element is the slow way to (accidentally) kill it.
Frequently asked questions
Where do you get Panthalus in Palworld 1.0?
You summon it by playing the Echoing Flute at the shrine on the Deserted Islet (far south). It doesn’t spawn anywhere in the open world — the flute is the only way to trigger the fight.
What are the four Echobones and where are they?
Marine (122, −525), Seafoam (−519, −548), Silent (356, −110) and Tidewind (−262, 485) Echobones, each taken from a giant-whale skeleton. The Ancient Civilization Researcher marks all four on your map when you start the quest.
How do you make the Echoing Flute?
Combine the four Echobones (one of each) at any workbench — a Primitive Workbench is enough. You get the recipe from the Faded Schematic the Researcher gives you on the Deserted Islet.
Do you have to catch Panthalus or can you kill it?
You must catch it. The fight is scripted to leave it at very low HP where any Pal Sphere works, but if it dies you have to redo the whole encounter — and you need the captured Panthalus in your party to open the World Tree.
What level is Panthalus and what’s it weak to?
It’s Level 70, Water-type, with roughly 350,000 HP, and weak to Electric — Beakon is a strong counter. The high HP is the scripted boss value, not its base stat.
The bottom line
Catching Panthalus comes down to a short checklist: beat the last tower boss to open the quest, grab the four Echobones off the whale skeletons, craft the Echoing Flute at any workbench, and summon the whale at the Deserted Islet — then capture it, don’t kill it. Carry it in your party and the World Tree’s outer barrier drops. Do that and you’re one gauntlet away from the end of Palworld 1.0 — with one of the game’s fastest mounts to show for it.
