How to Beat Panthalus in Palworld 1.0 (Final Boss Guide)

Panthalus is the giant whale boss that stands between you and the last part of Palworld 1.0. It has a huge health bar, hits hard with tidal waves, and there is one big catch most players miss: you are not supposed to kill it. You have to catch it. Get that wrong and you waste the whole fight. This guide walks you through the weakness, the prep, the Pals and weapons that make it easy, and the exact way to win.

Quick Answer

Panthalus is a Water type, so bring Electric Pals and Electric or heavy ranged weapons. It sits around Level 70, and you want to be Level 65 or higher to survive comfortably. The most important thing: you catch Panthalus, you do not kill it. Its health is designed to stop at 1 point no matter how much damage you do, and the catch at that point is scripted, so any Pal Sphere works, even a basic one. This is special to Panthalus. For normal high-level Pals you still need high-tier spheres, but here the catch is guaranteed. Bring a few spheres just in case.

How to Unlock the Panthalus Fight

Panthalus is part of the World Tree questline, so you need to do a few steps before you can summon it:

1. Beat Auri and Shaolong (around Level 68) at the Sunreach tower, then talk to Auri to move the story forward.
2. Speak to the Ancient Civilization Researcher at Deserted Islet.
3. Collect four Echobones from the whale skeletons scattered around the Palpagos islands.
4. Craft the Echoing Flute at any Workbench.
5. Go to the shrine on Deserted Islet and examine the glowing blue stone to summon Panthalus.

Tip: grab all four Echobones before you craft anything. Flying between the whale skeletons in one trip saves a lot of back and forth.

Prep Before the Fight

This fight is a race against a health bar and a timer, so go in ready.

• Level: Be at least Level 65, ideally close to 70. Lower than that and your damage is too slow to beat the catch timer.
• Pal Spheres: Bring 3 to 5 spheres. Any tier works here, even basic ones, since the catch is scripted. A few spares just cover you if something goes wrong.
• Weapons: A Mechanical Bow works great here, and Plasma or Assault weapons at your level do solid damage. Bring plenty of ammo.
• Armor: Wear the best level-appropriate armor you have. Tidal waves hit hard.
• Healing: Pack healing items and good food. You will take chip damage the whole fight.
• A fast mount: This is the real key. A quick flying or swimming Pal lets you dodge most of Panthalus’s attacks just by staying mobile.

Best Pals to Bring

Panthalus is Water type, so Electric Pals deal bonus damage:

• Beakon and Helzephyr Lux are the top Electric picks for extra damage.
• For mounts, Jetragon, Necromus, and Frostallion Noct are fast flyers that keep you out of harm’s way.
• If you prefer to fight on the water, Relaxaurus and Chillet are strong swimming mounts.

You do not strictly need Electric Pals, but they shorten the fight, which matters with the catch timer running.

How to Beat (and Catch) Panthalus

1. Summon Panthalus at the shrine by examining the glowing blue stone.
2. Get on a fast flying or swimming mount right away and close the distance.
3. Keep moving. Staying airborne dodges most of its moveset. If you fight over water, sit directly underneath the whale, where it struggles to hit you.
4. Pour on steady damage with your Pal and your own weapon at the same time.
5. Watch for tracker bubbles (they follow you, so keep moving) and tidal waves (heavy damage, dodge with your mount).
6. Grind its health down. It will not drop to zero, it stops at 1 point. This takes several minutes, so be patient.
7. Once its health bottoms out, throw any Pal Sphere. The capture is scripted and guaranteed, so even a basic sphere works.

That is the win. Panthalus joins your team.

Common Mistakes to Avoid

• Not bringing spheres. Panthalus can’t be killed, its health stops at 1 and you catch it there. No sphere means no reward. Carry a few.
• Standing still. Panthalus punishes players who stop moving. Stay on your mount.
• Going in under-leveled. Too little damage and you run out the clock before its health bottoms out.
• Waiting too long to throw. The moment its health hits the floor, throw a sphere. Do not keep attacking.

What You Get for Beating Panthalus

Catching Panthalus is what unlocks the endgame. Keep it in your active party and you can use the World Tree terminal, which drops the barrier to the Level 75+ final region. That area brings radiation zones, Radiant Gems, the Awakening mechanic, and the last story quest.

FAQ

Can you beat Panthalus solo? Yes. Solo is completely doable with a fast mount and Level 65+ gear. Co-op just makes it quicker.

What level should I be for Panthalus? Level 65 or higher. The boss is around Level 70, and 65+ lets you survive and deal enough damage in time.

What is Panthalus weak to? Electric damage. It is a Water type, so Electric Pals and weapons hit hardest.

What sphere do I need to catch Panthalus? Any Pal Sphere works, even a basic one, because this catch is scripted and 100% guaranteed once its health hits 1. That is unique to Panthalus. Normal high-level Pals still need high-tier spheres. Bring a few either way.

Can you kill Panthalus? No. Its health is designed to stop at 1 point, so you cannot defeat it. You wear it down and catch it with a Pal Sphere.
