The Legendary Plasma Rifle is a high-end ranged energy weapon in Palworld’s 1.0 update. It fires an electrical discharge that chains between nearby enemies on hit, which makes it strong for thinning out groups rather than trading blows with a single target. To build it, you first need the Plasma Rifle Schematic 4, which unlocks the Legendary recipe the moment it sits in your inventory.
Quick answer: Beat Saya and Selyne, Leader of the Moonflowers, at Level 80 on Hard difficulty for a 10% chance to drop the Plasma Rifle Schematic 4, then craft the rifle at an Ancient Workbench while the schematic is in your inventory.
Where the Legendary Plasma Rifle schematic drops
The most reliable source is the hard-mode fight against Saya and Selyne, who carry a flat 10% chance to drop the schematic. You must defeat them once on Normal difficulty before the Hard version of the fight becomes available.
The pair waits at the Moonflower Tower near the center of Sakurajima Island, at coordinates -597, 206. Even at 10% per clear, the drop is not guaranteed, so keep your ammo and loadout stocked for repeat attempts.

The schematic also appears in a few treasure and fishing sources, though the odds are far lower than the boss drop. Chase these only if you are already farming those spots.
| Source | Chance |
|---|---|
| Saya and Selyne Lv.80 (Hard) | 10% |
| World Tree fishing (WorldTree02) | 0.363% |
| World Tree treasure fishing | 0.264% |
| Treasure Map (TreasureMap05) | 0.149% |
| Glistening Ancient Relic | 0.029% |
| Glowing Ancient Relic | 0.008% |
| Gorgeous Ancient Relic | 0.003% |
| Dormant Ancient Relic | 0.001% |
Craft the Legendary Plasma Rifle at an Ancient Workbench
Once the schematic is in your bag, the Legendary recipe becomes available at the Ancient Workbench. The build demands a large stockpile of endgame materials and a heavy gold reserve.
| Material | Quantity |
|---|---|
| Paloxite Ingot | 160 |
| Bio Battery | 100 |
| AI Core | 16 |
| Ancient Civilization Core | 14 |
| Ancient Civilization Parts | 10 |
| Gold Coin | 1,120,000 |
Note: the standard Plasma Rifle unlocks through Technology at Level 78 and uses a lighter recipe of 7 Ancient Civilization Core, 50 Bio Battery, 8 AI Core, and 80 Paloxite Ingot. The Legendary version is the same weapon at maximum rarity, so pursue it only once you can spare the extra materials.
Build the schematic from lower-tier copies
You do not have to rely purely on the boss roll. If you collect lower-tier duplicates, you can promote them into the Legendary schematic at a Drafting Table. Combining five Plasma Rifle Schematic 3 produces a single Plasma Rifle Schematic 4, giving you a deterministic path once you have banked enough of them.
Legendary vs standard Plasma Rifle stats
The Legendary Plasma Rifle is a straight upgrade over the common model. Every core stat is higher, with durability jumping fourfold so the weapon lasts much longer between repairs.
| Stat | Legendary | Regular |
|---|---|---|
| Attack | 2,232 | 1,860 |
| Max Ammo | 46 | 38 |
| Durability | 100,000 | 25,000 |
Ammo supply matters as much as raw damage here. The chaining shots burn through the magazine quickly in longer fights, so set up a steady production line for Plasma Rifle Ammo before committing to it as your main weapon.
Confirm the rifle unlocked
You know the schematic worked when the Plasma Rifle (Legendary) shows up as a craftable option at the Ancient Workbench while the schematic sits in your inventory. If the recipe does not appear, the cause is almost always one of three things.
- The schematic is in storage instead of your inventory. The craft option will not appear unless it is carried on you.
- You are standing at the wrong crafting station. Only the Ancient Workbench builds this rifle.
- You have not gathered all the required materials or gold.
Fix those three points and the Legendary Plasma Rifle becomes craftable, giving you one of the strongest multi-target energy weapons in the game.
