Palworld Moon Lord Raid Guide: Start, Fight, Rewards

Moon Lord is the Terraria collab raid boss. The Sealed Realm of Terraria owns dungeon prep and Hallowed Bars. This page owns the Summoning Altar loop, the fight, and what you craft after a clear.

How to unlock and summon

• Clear Sealed Realm of Terraria and open the end chests for Celestial Sigil Schematic (guaranteed on that chest table).
• Craft Celestial Sigil from 100 Hallowed Bars at a workbench once the schematic is learned.
• Build a Summoning Altar (Technology level 33). Offer the Celestial Sigil the same way you offer other raid slabs.
• Summon at a dedicated raid base or a throwaway Palbox arena so the wipe does not flatten your main factory.

Celestial Sigil Schematic

Schematics

Learn this schematic to permanently unlock the Celestial Sigil.

Hallowed Bar

Materials

[Tides of Terraria] A sacred material infused with divine energy. Can be used to create a variety of Terraria items.

Celestial Sigil

Consumables

[Tides of Terraria] A seal inscribed with cryptic symbols. Offer to a Summoning Altar to summon a powerful entity.

Summoning Altar

Structures

Offer a Slab depicting a Pal to summon a powerful Pal to your base. Adequate caution and battle readiness is paramount.

Celestial Sigil [master]

Consumables

[Tides of Terraria] A seal inscribed with cryptic symbols. Offer to an Summoning Altar to summon an inconceivably powerful entity.

Recommended power

• Moon Lord has no element tag in live data. Build for raw damage, sustain, and mobility instead of chasing a weakness.
• Bring condensed combat Pals and late weapons. Terraria collab gear (Terra Blade, Vortex Beater, Terraprisma, Nightglow) shines here once schematics are unlocked.
• Raid rules match other slab bosses: you can field a large Pal team. Pre-place walls and turrets if you summon on a base pad.
• Celestial Sigil [master] summons the harder Moon Lord [Master] variant. Craft is not available; that sigil comes from clearing the normal raid.

Fight notes and wipe causes

• Moon Lord fights as a multi-part body (hands and head). Burst windows matter more than standing still and trading.
• Common wipe: summoning on your main base without a funnel. The boss deletes incubators and assembly lines you still need.
• Common wipe: under-leveled party after a fresh schematic unlock. Farm more Hallowed Bars and gear one full set before the first altar offer.
• Common wipe: ignoring True Eye of Cthulhu adds and projectiles while tunnel-visioning the torso.
• Exact phase HP thresholds are not published cleanly in our extracts. Learn the tells once, then repeat the same arena layout.

Rewards and what to craft next

• Item text: Luminite Bar is dropped by Moon Lord and fuels late Terraria crafts.
• Pal drop table for the raid lists Legendary Meowmere as a notable rolled reward (about one in five clears). Treat other loot as variable until your run logs it.
• Celestial Sigil [master] unlocks the Master difficulty rematch for higher stakes.
• Moon Lord Mask and Moon Lord Statue Schematic are collab flex crafts tied to the raid line.
• Legendary Meowmere recipe asks for Hallowed Bars, Paldium Fragments, and Coal once you can craft it. Pair with Hallowed Mask for the sword damage bonus.

Luminite Bar

Materials

[Tides of Terraria] A material exuding immense power, dropped by Moon Lord. Radiates a soft, moon-like glow.

Legendary Meowmere

Weapons

[Tides of Terraria] A legendary Meowmere forged from Luminite Bar. Swinging it launches cat projectiles that ricochet and attack foes.

Moon Lord Mask

Armor

[Tides of Terraria] Pulsing with Moon Lord's sinister energy. A rarity only the most fortunate may obtain.

Hallowed Mask

Armor

[Tides of Terraria] Helmet forged from Hallowed Bar. Enveloped in divine power, it increases damage dealt by Meowmere, Excalibur, Terra Blade, and Legendary Meowmere.

Preparing your arena before you summon

Do not offer the Celestial Sigil on the same pad you use for your main base defenses or production lines. Moon Lord's multi-part body covers a lot of ground and its projectiles do not care what they hit on the way past. Build a dedicated raid pad, whether that is an empty Palbox arena away from your factory or a walled-off corner you do not mind losing structures in.

Getting through your first attempt

• Do not rush the altar the moment you learn the schematic. Farm one more full set of Hallowed Bar gear from the dungeon first so your first pull is not also your worst-geared attempt.
• Bring healing items and repair mats you would normally consider excessive. Multi-part raid bosses punish under-stocked players harder than single-target fights.
• Focus fire on one part of the boss instead of spreading damage across hands and head evenly. A concentrated kill order clears faster than trying to whittle everything down together.
• If your first attempt wipes, that is normal. Note which phase killed you, gear up specifically for that threat, and go again rather than reworking your whole party blind.
