Celestial Sigils are consumable items that players can get inside the Sealed Realm of Terraria dungeon in Palworld. These work the same as the slabs used to challenge raid bosses, but instead of needing to collect fragments, all you need are Hallowed Bars, which you can also get from the same dungeon. Once you get a Celestial Sigil in Palworld, you'll be able to fight the Moon Lord raid boss for a chance to get some unique loot.
Where to Get Celestial Sigil Schematics in Palworld
You can find the crafting schematics for Celestial Sigils at the end of the Terraria dungeon in Palworld. Once you reach the end of the dungeon, you'll find two chests near the exit portal. Opening these have a chance to drop the Celestia Sigil Schematic, which will unlock the item for crafting at any Workbench of Production Assembly Line for as long as you have the schematics in your inventory.
The Celestial Sigil Schematic is not guaranteed to drop, though it shouldn't be too hard to get. If you don't get it on your first run, leave the dungeon and come back after three minutes. Rush to the end and open the chests again for another shot at getting the recipe.
Crafting Celestial Sigils
All you need to make Celestial Sigils are Hallowed Bars. You'll need 100 of them, to be exact, so expect to do a bit of grinding. Hallowed Bars drop from the monsters and Pals inside the Sealed Realm of Terraria dungeon, though you can also get some by mining the yellow walls in the underground area, and by opening the chests found in the side areas of the dungeon.
Pretty much every recipe you find inside the Terraria dungeon requires Hallowed Bars by the hundreds. Make sure to get as much as you can during every run.
Where to Get Master Celestial Sigils
The Master version of Celestial Sigils can be obtained by defeating the Moon Lord raid boss in Palworld. This is similar to all other raid bosses that drop Slabs for their Ultra variants. Both Celestial Sigil variants can be used at Summoning Altars, and you can challenge the Moon Lord boss for as long as you have sigils to spare.
Much like the other raid bosses in Palworld, you can either fight Moon Lord in one of your bases, or teleport to a dedicated raid boss arena. The former lets you use pre-built buildings to your advantage, while the latter gives you more space to work with. In any case, you can summon up to 15 Pals to help you during the fight. Moon Lord has no elemental weakness, so your best bet at beating him is to use Pals with very high raw damage output. Condensing Pals will increase their stats and level up their Partner Skill, making this a great way to improve their stats.
