Palworld is an open-world survival game where you explore islands, catch Pals, build bases, craft weapons, and take on increasingly difficult bosses. The 1.0 update adds the World Tree as a major endgame area, leading to the final Zenara and Astralym battle. To unlock Zenara and Astralym in Palworld 1.0, you must finish the Panthalus quest, gain entry to the World Tree, defeat three guardian encounters, and collect eight Tower Boss Key Spheres. This guide covers the full route, including the Sunreach tower that many players miss.
Key Takeaways
- Zenara and Astralym are Palworld 1.0’s final boss encounter, found beyond the Sealed Sanctum in the World Tree.
- You must collect four quest items, craft the Echoing Flute, defeat Panthalus, and capture it before the World Tree becomes accessible.
- The final door requires eight Tower Boss Key Spheres from all tower bosses, including Auri and Shaolong in Sunreach.
- Astralym is currently not obtainable as a playable Pal. Defeating the fight adds it to your Paldeck, but you cannot catch or breed it.
The full route has several locked doors and quest steps, so it is easy to think you are stuck when you have only missed one requirement. Complete the steps below in order to reach the final arena.
Can You Catch Astralym?
No. As of October 2026, Astralym cannot be caught, bred, hatched, or obtained as a reward after its boss fight.
Astralym is a boss-exclusive Pal in the Zenara and Astralym encounter. Beating the fight adds it to your Paldeck, but it does not put Astralym in your Pal Box or allow you to use it in battle. It also does not appear as a normal wild spawn or Alpha Pal.
This matters because many players search for “how to get Astralym” when the actual progression goal is reaching and defeating the final boss.
Start the World Tree Quest
The World Tree is the main gateway to Zenara and Astralym. Reaching the terminal alone does not give you access.
When you first interact with the World Tree terminal, it tells you that mysterious energy is blocking the way. You need to begin the nearby questline to remove that barrier.
Speak to the Researcher NPC
Travel to the quest NPC near the World Tree route and exhaust their dialogue. The NPC is researching ancient civilizations and giant whale remains.
After speaking with them, you receive the Echoing Flute blueprint. The quest also marks four collection spots on your map.
These marked locations contain the items required for the next step. Do not head back to the World Tree terminal yet, because it will remain locked until the entire Panthalus sequence is finished.
Collect Four Whale-Remain Items
Visit all four marked locations and collect the quest items. These are connected to the giant whale remains referenced by the NPC.
The game places all required points on the map, making this part mostly an exploration task. Clear nearby enemies and carry healing items if you are underleveled for the region.
Once you have all four items, return to your base.
Craft the Echoing Flute
Use a Primitive Workbench to craft the Echoing Flute.
The flute is not just a collectible quest item. It is required to trigger the next stage of the World Tree route and start the Panthalus boss encounter.
Before returning to the quest area, make sure you bring Pal Spheres. You will need to capture the boss after defeating it.
Defeat and Capture Panthalus
Return to the NPC after crafting the Echoing Flute. Speak with them again and activate the shrine next to the quest giver.
This starts the Panthalus boss battle.
Panthalus is the giant whale Pal tied to World Tree progression. While the encounter is easier than the late-game Zenara and Astralym battle, it is still important to arrive prepared with healing, ammunition, and a few strong Pals.
The key requirement is simple: you must capture Panthalus after defeating it.
Do not leave after bringing its health down. Throw a suitable Pal Sphere and secure the capture before ending the encounter. If you forget Spheres, check the nearby beach area, but bringing your own is safer.
After catching Panthalus, talk to the NPC once more. This completes the first major stage and unlocks the World Tree mission.
Enter the World Tree
Return to the World Tree terminal after capturing Panthalus.
Interact with the terminal or altar again. Panthalus’s power now lets you pass through the energy barrier and enter the World Tree region.
The World Tree is a major Palworld 1.0 endgame zone. It is tied to the updated story, difficult boss content, powerful materials, and the route to the final encounter.pindrop+1
Activate any fast-travel point you find as soon as possible. You will revisit this region several times while completing the guardian encounters and opening the sealed doors.
Defeat the Three World Tree Guardians
Once inside the World Tree, follow the quest path toward the large central structure. This is the same area you will eventually use to reach Zenara and Astralym.
The first time you approach the main door, you cannot enter. Interact with the nearby lore objective to receive the next quest step.
The quest sends you to three marked boss encounters around the World Tree region.
Defeat all three encounters to obtain the items needed to unlock the first sealed entrance. The fights are separate from the eight tower bosses and should not be skipped.
One of the encounters includes several Shadow Pal enemies. This battle can become difficult if your team is already weak from exploration, so heal your active Pals and prepare enough ammunition before you enter.
Once all three guardian battles are complete, return to the main door and use the quest items to open it.
Get All Eight Tower Boss Key Spheres
Beyond the first World Tree door, you will reach a second sealed entrance. This is the final lock that protects the Zenara and Astralym arena.
The door requires eight Tower Boss Key Spheres.
You earn the required Key Spheres by defeating all tower bosses in Palworld. Normal difficulty clears are enough for this progression requirement. You do not need Hard Mode clears just to open the final door.
Tower Boss Key Sphere Checklist
| Tower Boss | Requirement |
|---|---|
| Zoe and Grizzbolt | Defeat the boss in its tower |
| Lily and Lyleen | Defeat the boss in its tower |
| Axel and Orserk | Defeat the boss in its tower |
| Marcus and Faleris | Defeat the boss in its tower |
| Victor and Shadowbeak | Defeat the boss in its tower |
| Saya and Selyne | Defeat the boss in its tower |
| Bjorn and Bastigor | Defeat the boss in its tower |
| Auri and Shaolong | Defeat the new Sunreach tower boss |
Open your inventory and check the Key Items section before searching again. If you are missing one Key Sphere, you have either skipped a base-game tower or have not completed Auri and Shaolong in Sunreach.
How to Unlock Auri and Shaolong
Auri and Shaolong are the eighth tower boss added with Palworld 1.0. This is usually the final Key Sphere that blocks players from opening the Sealed Sanctum door.
The tower is located in the new Sunreach floating-island region. When you arrive, a tornado or whirlwind prevents normal access.
Fly into the tornado to reach the quest NPC nearby. Speak with the NPC to learn that you need to disable several defense systems across Sunreach.
Disable the Sunreach Defense Systems
Explore the floating islands and watch for blue beams of light. These beams point toward buildings or nearby locations with active defense systems.
You must find and disable all of them before the tornado disappears.
Some systems are inside buildings. Instead of climbing every floor, look for a quick route from higher ground. Breaking through a wall may give you a faster way to reach the interaction point.
The blue markers may only become visible when you are close to their locations. If you cannot see another beam, keep exploring each island and watch your minimap.
After disabling every defense system:
- Return to the Auri and Shaolong tower.
- Start the tower boss battle.
- Defeat Auri and Shaolong.
- Collect the eighth Tower Boss Key Sphere.
You can now finish the final World Tree lock.
Open the Sealed Sanctum Door
Return to the World Tree with all eight Key Spheres.
Go through the first door you opened after defeating the three World Tree guardian encounters. Continue through the area until you reach the second sealed door.
Interact with it again. If your Key Items tab contains all eight Key Spheres, the door opens and gives you access to the Sealed Sanctum.
Zenara and Astralym are waiting inside. They serve as the final boss encounter for Palworld 1.0, and the fight is built for late-game players.game8+1
How to Prepare for Zenara and Astralym
Zenara and Astralym are not a fight to enter with an unfinished Pal team. Prepare as if you are heading into Palworld’s most demanding story encounter.
Bring a complete party of your strongest combat Pals. Prioritize Pals with high damage, reliable attacks, and enough health to survive long exchanges.
Your character should also have strong armor, a high-damage ranged weapon, enough ammunition, healing items, and revival supplies. Keep your strongest damage options ready for the later part of the battle.
The boss has a difficult late phase that requires players to deal sustained damage in a limited window. Saving powerful abilities, avoiding unnecessary damage earlier in the fight, and entering with a full team can make the final section much easier.
Astralym has no elemental weakness, so build around your strongest raised and well-equipped Pals instead of relying on a single type advantage.
What You Unlock After Beating Them
Defeating Zenara and Astralym completes Palworld 1.0’s main endgame boss route.
Astralym is added to your Paldeck, but you do not receive Astralym as a playable Pal. You also cannot catch it after the battle, even if you bring Pal Spheres into the arena.
The completion is still worthwhile for players who want to finish the main 1.0 progression, complete their Paldeck records, and take on the World Tree’s toughest battle.
