Panthalus is the Level 70 Water-type boss standing between you and the World Tree in Palworld 1.0. It has more than 350,000 HP, fights on an open ocean arena with a single tiny island, and cannot be found in the wild. You summon it yourself after a short scavenger hunt, then win by exploiting its Electric weakness while staying airborne.
Quick answer: Ride a fast-flying Electric Pal like Beakon or Helzephyr Lux, fly above the water and hit the blue crystal on Panthalus’ head with a Rocket Launcher, Plasma Cannon, or Multi-Guided Missile Launcher, dodge its large water attacks by flying out over the sea, and throw any Pal Sphere the moment it drops to 1 HP for a guaranteed catch.
Unlock the Panthalus fight: Echobones and the Echoing Flute
You can start the quest at any time by visiting the Ancient Civilization Researcher on the Deserted Islet, a small island west of the No Man’s Trail fast travel point. In the main story, the quest becomes available after completing The Calamity, when you speak with Auri near the cliff outside the Azure Covenant Tower. Either way, you are tasked with collecting four Echobones from the giant whale skeletons scattered across the Palpagos Islands.
Once the quest is active, each Echobone location shoots a yellow beacon into the sky, which makes them easy to spot from the air.
| Echobone | Nearest fast travel point | Where to look |
|---|---|---|
| Marine Echobone | Grassy Behemoth Hills | West of the point. Climb the skeleton’s skull and examine the glowing object. |
| Silent Echobone | Mossanda Forest / Altar of the Wind Caller | Behind the larger bones of the giant skeleton. |
| Seafoam Echobone | Eternal Pyre Tower Entrance | East of the tower. Enter the skull and examine the object inside. |
| Tidewind Echobone | Land of Absolute Zero | Beside the base of the skeleton’s skull. |
After collecting all four bones, return to any base and craft the Echoing Flute at a workbench such as the Primitive Workbench. Bring the flute back to the Deserted Islet, speak with the researcher, then examine the glowing blue stone to summon the boss.
Tip: The encounter begins the instant you trigger it, so finish your entire loadout before you interact with the stone.
Best Pals and loadout for the Panthalus fight
Panthalus is a pure Water-type, so Electric damage is by far the most effective. The arena is almost entirely ocean, which makes ground-based Pals useless. Reach at least Level 71 so you can equip the Ancient Shield and level your Pals to match. A fast flying mount keeps you above the water, where your damage is highest, and lets you outrun the boss as it moves around the arena.
| Pal | Role |
|---|---|
| Beakon | Fast Electric flying mount with strong mobility for dodging large AoE attacks. |
| Helzephyr Lux | Electric/Dark flying mount with powerful Electric attacks and good survivability. |
| Solmora Lux | Water/Electric swimming mount whose Partner Skill converts your attacks to Electric damage. |
For weapons, bring the highest-damage endgame gear you own. A Rocket Launcher offers strong burst damage and long range so you can fire while mounted. A Plasma Cannon or Multi-Guided Missile Launcher works as reliable backup damage to beat the timer. For armor, the Ancient Armor, Ancient Helm, and Ancient Shield give the best protection against Panthalus’ water attacks.
Crucially, bring plenty of Pal Spheres. Panthalus is designed to be captured, and a basic sphere is all you need once it hits 1 HP.
Panthalus attacks and both fight phases
Panthalus prefers to keep its distance and fills the arena with wide water attacks. Learning the patterns matters more than raw defense, because several attacks cover almost the entire island.
| Attack | What it does |
|---|---|
| Bubble Rain | Fires homing bubbles from its crown that linger and burst on impact or after a few seconds. |
| Creeping Bubbles | Surrounds you with bubbles that slowly merge toward the center and explode. |
| Aqua Blade | Launches large, sharp water blades. |
| Tidal Charge | Body slam that spawns a wave moving in one direction. |
| Maelstrom | A shrinking vortex that pulls you in and ends in a water pillar explosion. |
| Grand Breach | Dives, then leaps out, sending damaging ripples outward. |
| Aqua Tornado | Summons multiple massive tornadoes that slowly track you. |
| Tsunami | A huge wave you can only clear with a flying Pal or the island’s air pressure jump. |
Once its health drops to around half, Panthalus enters a second phase and starts glowing. It leans heavily on Aqua Tornado and Maelstrom here and begins summoning Tsunamis across the arena. It also moves closer and uses devastating body slams. If you are directly underneath it during a slam, it is a guaranteed instant kill, so keep moving after every shot and never sit still.
How to beat Panthalus
Capture Panthalus at 1 HP
Once Panthalus is reduced to its final point of health, throw any Pal Sphere. The capture is scripted and 100% guaranteed, so there is no reason to use a higher-tier sphere or weaken it further. You will know it worked when Panthalus is added to your Paldeck.
After the catch, speak with the Ancient Civilization Researcher to complete the quest. If you defeat Panthalus again later, it respawns immediately with no waiting time, so you can refight it to catch duplicates or farm its loot as often as you like.
What Panthalus unlocks
Capturing Panthalus is the key to progressing the main story. With the ocean king in your party, head to the World Tree gate terminal to bring down the barrier and access the game’s final story sequence. Panthalus itself is a No. 203 Water Pal with high HP and Defense, and it ranks as an S-Tier flying mount, making it a strong pick for exploration once the fight is behind you.
