Summoning Bellanoir in Palworld is not a matter of stumbling into the right biome. The game's first true raid boss requires you to build a specific item from scratch, gather it from some of the most dangerous locations on the map, and then set up a dedicated fight zone before you even think about pressing the summon button. Get any step wrong and you lose the slab, the fight, and potentially your base.
What is Bellanoir's Slab and why does it matter?
Bellanoir's Slab functions as a single-use raid ticket. You craft it, slot it into a Summoning Altar, and the Eclipsed Siren spawns directly inside your base perimeter. The moment the fight begins, the slab is consumed. Win or lose, you need to go back and farm four more fragments if you want another shot.
The slab cannot be found pre-assembled anywhere in the world. You build it entirely from Bellanoir's Slab Fragments, and those only drop from specific high-risk locations. This gating is intentional: the raid is tuned for endgame players, and the fragment hunt is part of the preparation.
Place the altar away from your Palbox
Where to find all Bellanoir's Slab Fragments
You need exactly 4 fragments to craft one slab. They are RNG drops, so the number of runs required varies significantly between players. Here are the three confirmed sources:
Which source is most efficient?
High-level dungeons at Level 45 and above are your best starting point. The golden chest at the end of a dungeon run has the highest reported drop rate, but you must clear the entire dungeon to reach it. Do not skip the final room after killing the dungeon boss.
Wildlife Sanctuaries are the most consistent fallback. Running all three sanctuary islands in sequence can yield anywhere from 4 to 9 fragments in a single sweep, which makes them worth hitting if dungeon RNG is running cold. Mineshafts are worth looting if you pass through them anyway, but farming them specifically is slower than the other two options.

How to craft Bellanoir's Slab
Step 1: Reach Level 33 and unlock the Summoning Altar
The Summoning Altar is gated behind Level 33 in the Technology Tree. It costs 3 Ancient Technology Points to unlock. You will need this structure before the slab has any use, so unlock it as soon as you hit the level requirement.
Step 2: Collect all 4 fragments
Farm dungeons, sanctuaries, and mineshafts until you have 4 Bellanoir's Slab Fragments. The fragments do not need to be in your personal inventory for the crafting recipe to appear, though some players report the recipe only populates when the fragments are physically on their character. If the recipe is not showing up at your workbench, move the fragments from base storage into your inventory.
Step 3: Craft the slab at a workbench
With 4 fragments available, head to a production table or assembly line at your base. Current game behavior allows any workbench to combine the fragments, though older builds required the Production Assembly Line II (unlocked at Level 42). If the recipe is not appearing at a basic bench, try the Production Assembly Line II instead.
Step 4: Build the Summoning Altar
Construct the Summoning Altar using 100 Stone and 20 Paldium Fragments. Build this at a dedicated raid location, not your main base. A remote base with your Palbox, the Altar, and some defensive turrets is the safest setup.
Step 5: Place the slab and summon
Interact with the completed Summoning Altar and slot the Bellanoir's Slab in. Before confirming the summon, make sure your active team includes Dragon-type Pals (Bellanoir is a Dark-type, making Dragon moves your strongest option) and that you have high-tier ranged weapons equipped. An Assault Rifle or Rocket Launcher is recommended.
Once you confirm, the altar is consumed and Bellanoir spawns. You have 10 minutes to defeat her.
How to avoid losing your base during the raid
Bellanoir hits hard and her AoE attacks will tear through structures near the altar. The standard advice is to build a dedicated raid base at a remote location with nothing you care about losing. Place your Palbox at the far edge, put the Altar in the center of an open area, and strip out any crafting benches or storage you would miss.
For solo players, mounting a fast Pal like Chillet or Jetragon and kiting Bellanoir around the arena works better than standing still and trading hits. Keep distance, let your base Pals absorb her attention, and deal ranged damage from a mount.
What comes after Bellanoir?
Once you clear the base version of the raid, fragment hunting does not stop. There are harder versions of the encounter: Bellanoir Libero and the Ultra difficulty variant, each requiring their own set of fragments and offering better rewards. The fragment-gathering loop repeats for every version, so getting efficient at dungeon and sanctuary runs pays off long-term.
