Raid Bosses

By ScotUpdated

Tactical Quick Answer

Raid bosses are summoned at a Summoning Altar unlocked in the Ancient Technology tree at Level 33, the altar is consumed on use, and you get 10 minutes to kill each boss. Summoning at a separate outpost is still the safe play, though since v0.7.0 the altar opens its own dimension for the fight. Bring two elemental team compositions, since Blazamut Ryu shifts to Electric partway through and Bellanoir Libero shifts to Ice.

Raid bosses operate outside the normal overworld spawn system. You summon them at your base using a Summoning Altar and fight them within a strict time limit. These encounters demand optimized Pal teams, dedicated base infrastructure, and active party management during multi-phase transitions.

Building the Summoning Altar​

Unlock the Summoning Altar in the Ancient Technology tree at Level 33. It costs 3 Ancient Technology Points, 100 Stone and 20 Paldium Fragments, all four values exactly as stated. Note that the altar is destroyed when you use it, so budget for rebuilding.

warning

The standard advice is to build a barren sacrificial outpost so raid damage cannot touch your production base, and that was solid guidance for most of the game's life. Treat it as cautious and not mandatory now: since v0.7.0 the altar can summon Pals into their own dimension, and the raid is described as fought in a special realm the altar opens. How much base damage still occurs in v1.0 is not cleanly documented, so a throwaway outpost remains the safe play until it is.

You have 10 minutes to defeat the boss. On team size, you can summon as many Pals as your base can hold, and the commonly quoted figure of 15 to 20 appears in no source. Only one raid per guild can run at a time in v1.0.

Crafting Summoning Slabs​

Slabs are the keys that initiate each raid encounter, and each takes four Slab Fragments of the matching type. You can craft them at a Primitive Workbench or better, so this is not gated behind a high tier assembly line.

Fragments come from dungeon treasure boxes, and not only in Sakurajima and Feybreak. Xenolord Slab Fragments drop in Feybreak Cavern at 25.253%, and Hartalis Slab Fragments in the Sunreach Skies at 33.333%.

Ultra slabs work differently: they drop from the normal version of the same boss, so you farm your way up the tier instead of finding them in the world.

Tier 1: Bellanoir​

Bellanoir comes in three versions now. Standard Bellanoir is Level 35 with 333,000 HP and teaches the summoning mechanics. Bellanoir Libero is Level 45 with 411,000 HP, and an Ultra Libero at Level 80 carries 2,394,000. The Level 30 and 50 figures you may have seen are pre-1.0.

Both are Dark type, so bring Dragon Pals. Bellanoir's attacks are primarily melee range, so keep your distance with ranged weapons and let your base Pals absorb the aggro.

One phase detail that is easy to miss: Libero transitions to Ice in its second phase, so pack Fire for the back half of that fight.

Tier 2: Blazamut Ryu​

Blazamut Ryu (Level 55) is where raid difficulty spikes dramatically. This Dragon/Fire type boss hits hard and features the most punishing phase transition in the game.

During the first phase, Water type Pals dominate. Deal consistent damage while dodging its sweeping fire breath attacks. The turn comes when it drops to 50,000 HP out of roughly 520,000, not at 1 HP: it goes temporarily immortal, recovers about 150,000 HP, and switches to Electric. Your Water Pals are now at extreme risk.

Immediately recall all Water Pals and deploy Ground types like Anubis, Knocklem, or Digtoise. The electrical attacks in the second phase are devastating to anything weak to Electric. Failing to swap your team results in a near-instant party wipe.

Tier 3: Xenolord, Moon Lord, and Hartalis​

These represent the absolute pinnacle of PvE content in Palworld.

Xenolord (Level 65) is Dark/Dragon with 1,414,000 HP. Slab fragments come from Feybreak Cavern dungeon treasure boxes, not from expeditions. Its aerial phase rains meteors and spawns Xenovader adds alongside Xenogards.

On counters, ignore the reasoning you may have read. There is no "standard Dragon weakness to Dragon attacks" in Palworld, since Dragon is weak to Ice. Against a Dark/Dragon target both Ice and Dragon resolve to 2x, so Ice is a fine pick but not uniquely optimal. The claim that the achievement fails if a base Pal lands the kill is undocumented.

Moon Lord (Level 50) came from the Tides of Terraria collaboration. Summoning takes a Celestial Sigil crafted from 100 Hallowed Bars, which is exactly right. Deploy high-defense base Pals to draw aggro while you manually target its exposed eyes and central heart core with heavy firearms. It also spawns three True Eyes of Cthulhu.

The Level 80 version is [Master] Moon Lord, and note that "Master" is its own tier here, distinct from the "(Ultra)" tier the other four raids use. The Celestial Sigil [Master] is a 100% drop from beating the base Moon Lord, so you unlock the harder version by clearing the easier one. What the Sealed Realm of Terraria chest gives, also at 100%, is the ordinary Celestial Sigil Schematic. That realm is real, but its coordinates and a Level 45 Eye of Cthulhu guarding it are undocumented, and the Eye of Cthulhu cannot appear as a field Alpha at all.

Hartalis (Level 70) has 972,000 HP, with an Ultra at Level 80 carrying 1,952,000. The base Pal is Neutral, not dual-typed.

The two phases are real and phase one genuinely is Water/Grass, with phase two Neutral. But the barriers are element-keyed, not health-keyed: phase one's breaks to Fire or Electric and phase two's to Dark. The 600,000 and 300,000 HP thresholds appear in no source. At the phase break Hartalis performs an area attack, not a raid wipe with a full heal.

Orserk is a solid phase-one pick, and Helzephyr Lux really is Dark/Electric and really does break the phase-two barrier, though Frostallion Noct is the more commonly recommended answer there. Paladius being mandatory is unsupported.

The Ultra Tier​

Four of the five raids have an (Ultra) version at Level 80: Bellanoir Libero Ultra, Blazamut Ryu Ultra, Xenolord Ultra and Hartalis Ultra. Moon Lord's top tier is branded [Master] instead. The full v1.0 raid roster is eleven encounters once you count both tiers.

What v1.0.3 Changed​

Two reward tables were wrong and are now right. The reward settings for the normal Moon Lord battle and for the Ultra Raid Boss battle had not been updated to their intended settings, and v1.0.3 corrected both. If you cleared either before August 12, 2026, what you were paid was not what the fight was meant to pay.

The same patch fixed some raid boss battles failing to progress as intended.

Raid Preparation Checklist​

Before summoning any raid boss, confirm the following:

  • Your summoning outpost has no valuable structures inside the base radius
  • You have as many combat Pals assigned as the base will hold
  • You have materials to rebuild the altar, since it is consumed on use
  • You carry at least two elemental team compositions for phase transitions
  • Your personal weapons and ammunition are fully stocked
  • You have healing items ready for both yourself and your Pals

Frequently Asked Questions​

How do you unlock the Summoning Altar in Palworld?

It sits in the Ancient Technology tree at Level 33 and costs 3 Ancient Technology Points, 100 Stone and 20 Paldium Fragments. Keep spare materials, because the altar is destroyed when you use it.

Can you summon a raid boss at your main base?

A throwaway outpost is still the safe play, but the reasoning has shifted. Since v0.7.0 the altar summons Pals into their own dimension and the fight happens in a special realm it opens. How much base damage still occurs in v1.0 is not cleanly documented, so keep valuables out of the radius until it is.

How do you beat Blazamut Ryu in Palworld?

Lead with Water Pals in phase one while dodging its fire breath. When it drops to 50,000 HP out of roughly 520,000 it goes briefly immortal, recovers about 150,000, and switches to Electric. Recall every Water Pal at that point and deploy Ground types like Anubis, Knocklem or Digtoise.

What counters Xenolord in Palworld?

Ice or Dragon, and they are equally good. Against a Dark/Dragon target both resolve to 2x, so the claim that Ice is mathematically optimal because Xenolord lacks a Dragon weakness is wrong on its own terms, since Dragon is weak to Ice in this game and not to itself. Xenolord is Level 65 with 1,414,000 HP.

How many Pals do you need for a raid?

As many as your base can hold. The frequently quoted 15 to 20 figure is not documented anywhere. They fight with their own AI while you use heavy weapons from the perimeter, and you have 10 minutes. Do not confuse that with the Tower Boss timer, which v1.0 cut to 5 minutes.
