Quick answer: Panthalus is Paldeck No. 203, a level 70 Water story boss you summon with the Echoing Flute on the Deserted Islet — and it is the only way to get one. Finish the Panthalus main quest, collect four Echobones from giant whale skeletons, craft the flute, then beat it down to 1 HP inside ten minutes and throw any sphere for a guaranteed capture. It cannot be bred, has no wild spawn, and carries the best stat line in the game: 120 Attack, 180 HP and 200 Defense.
Nowhere in the wild. Panthalus has no wild spawn, no dungeon appearance and no field Alpha (Game8; palworld-db.com) — it only appears in one fixed story encounter. The Panthalus main quest opens after you finish The Calamity: Game8's walkthrough has Auri at the Azure Covenant Tower pointing you toward it, and the trail leads to the Ancient Civilization Researcher on the Deserted Islet, a small island in open water west of the No Man's Trail fast travel point (Game8). Talk to the researcher and the quest begins.
The quest then sends you hunting for four Echobones, each hidden inside a giant whale skeleton (Game8):
| Echobone | Where to find it |
|---|---|
| Marine Echobone | West of the Grassy Behemoth Hills fast travel point — climb the giant skeleton's skull and examine the glowing object (Game8). |
| Silent Echobone | Near the Mossanda Forest fast travel point, hidden behind the larger bones of the giant skeleton (Game8). |
| Seafoam Echobone | East of the Eternal Pyre Tower Entrance — enter the giant skeleton's skull and examine the glowing object inside (Game8). |
| Tidewind Echobone | Near the Land of Absolute Zero fast travel point, beside the base of the giant skeleton's skull (Game8). |
Once all four are in your bag, craft the Echoing Flute at any workbench, return to the Deserted Islet, show the flute to the researcher, and examine the glowing blue stone to summon Panthalus (Game8). The fight is the gate to the World Tree: capturing Panthalus unlocks the endgame region at the top of the map, so this is not an optional side boss — it is the door to everything after it (Game8; TheGamer).
Panthalus is a level 70 Water boss with a ten-minute timer, and the arena is one small island surrounded by open water (Game8; vgkami). Game8 recommends reaching at least level 71 — that unlocks the Ancient Shield (Technology 71), alongside the Ancient Helm and Ancient Armor (68) and the Rocket Launcher (65), which Game8 calls the best weapon for the fight thanks to its burst damage and long range.
Fight mounted on a flying Pal. Panthalus spends most of the battle moving around the ocean, so chasing it on foot wastes the timer (Game8). Bring Electric damage — Water is weak to it — and Game8's recommended partners are Beakon (a fast flying mount with Electric attacks; see our Beakon guide), Helzephyr Lux and Solmora Lux, whose partner skill converts your attacks to Electric while mounted. When its huge wave comes, ride the Wind Turbulence air currents in the arena — get inside one and jump to fly over the wave (TheGamer). Aim for the blue sigil on its forehead, its weak point (Game8; vgkami).
Then the strange part. Panthalus cannot be taken below 1 HP, and it is immune to spheres while the fight is running. Once it is stunned at 1 HP, throw any sphere — a plain Pal Sphere works — for a guaranteed capture (Game8; vgkami; TheGamer). Do not waste an Ultra Sphere, and do not keep attacking after it hits 1 HP: the encounter can break and the quest cannot complete (palworldcompanion). After the capture, speak to the Ancient Civilization Researcher again to finish the quest and open the World Tree.
No — and this is the one place where the raw game data misleads. The 1.0 combination table does contain a Panthalus + Panthalus row, which is why some calculators list it as breedable. In the game itself it is not: Panthalus is the largest Pal in the game, it cannot be assigned to the Breeding Farm, and it cannot be hatched from any egg — the boss fight is the only way to obtain one (Game8; palworldonline.net, checked against Game8 and the Palpedia wiki on 21 September 2026).
That has two knock-on effects. First, there is only ever one Panthalus per playthrough from the story encounter, so you cannot condense it with duplicates the way our condenser guide describes for other Pals — Game8 notes you raise its partner skill rank with Starfruits instead. Second, check any pair in our breeding calculator before trusting a third-party list: the file row exists, but the farm door is closed.
From the 1.0 game files, Panthalus is Paldeck No. 203, Water, rarity 10, with 120 Attack, 180 HP and 200 Defense — a combined 500, the highest total of all 299 Pals (next is Frostallion Noct at 415). Its HP is ranked 1st of 299 and its Defense is also 1st; only its Attack, 32nd, keeps it from topping every column. It has no work suitabilities at all — one of only two Pals in the Paldeck with none — so it will never work a base job (palworld-db.com).
Its partner skill, Resonant Guardian, is why it stays useful after the fight (Game8): Panthalus can be ridden as a flying mount, and only one can be summoned to a base at a time. While stationed at a base it constantly patrols the skies and bombards intruders from above, and its damage rises with skill level — Damage Up S at level 2, M at 3, L at 4 and XL at 5, raised with Starfruits. As a mount it flies at 700 and sprints at 3,000 — the second-fastest flying mount in the game, behind only Jetragon at 3,300 (see our fastest flying mounts ranking and our Jetragon guide).
Its active skills are all Water except one (palworld-db.com): Bubble Rain (200 power, level 1), Creeping Bubbles (200, level 7), Aqua Blade (300, level 15), Tidal Charge (400, level 22), Maelstrom (500, level 30), Grand Breach (700, level 40), Holy Burst (700, Neutral, level 50) and Aqua Tornado (800, level 60). Its drops are a Diamond and a Giant Pal Soul, both guaranteed (Game8).
It has no wild spawn. Summon it on the Deserted Islet (west of the No Man's Trail fast travel point) by crafting the Echoing Flute from four Echobones — Marine (Grassy Behemoth Hills), Silent (Mossanda Forest), Seafoam (Eternal Pyre Tower) and Tidewind (Land of Absolute Zero) — then showing the flute to the Ancient Civilization Researcher (Game8).
No. The game files contain a Panthalus + Panthalus row, but Panthalus cannot use the Breeding Farm and cannot hatch from any egg — the level 70 boss fight is the only way to get one (Game8; palworldonline.net). You get one per playthrough.
Beat it down to 1 HP inside the ten-minute fight — it cannot go below 1 HP — then throw any Pal Sphere for a guaranteed capture (Game8; vgkami). Fight mounted on a flying Pal, bring Electric damage, aim for the blue sigil on its forehead, and ride Wind Turbulence currents over its waves. Game8 recommends level 71+ with the Ancient Shield.
Game files: Paldeck No. 203, Water, rarity 10, 120 Attack (32nd), 180 HP (1st), 200 Defense (1st), total 500 — the highest of all 299 Pals. Mount: fly 700, sprint 3,000 (2nd fastest). No work suitabilities. Drops: Diamond and Giant Pal Soul, both guaranteed (Game8).
Yes — it is required to enter the World Tree, it has the best stat line in the game, and it is the second-fastest flying mount. Its limits are real (no Tower Boss or World Tree fights, no base work, one copy only), but nothing else in the game does what it does.
