The Legendary Combat SMG is the top-tier version of the Combat SMG in Palworld, with far higher attack, more ammo capacity, and much greater durability. Before you can build it, you need to find its schematic, which only drops from a handful of late-game locations at very low rates.
Quick answer: Get the Legendary Combat SMG Schematic from a Legendary Treasure Map (0.297%), from chests on Sunreach (0.094%), or from chests in the Sunreach Skies Dungeon (0.094%). Keep the schematic in your inventory, reach Level 68, and craft it at an Ancient Workbench.
Where the Legendary Combat SMG Schematic drops
There are three confirmed ways to obtain the schematic. All of them are tied to Feybreak and Sunreach content, and each has a low drop rate, so expect to repeat runs.
| Source | Drop rate |
|---|---|
| Legendary Treasure Map (from Feybreak Sea Bases) | 0.297% |
| Chests on Sunreach | 0.094% |
| Chests in Sunreach Skies Dungeon | 0.094% |
Legendary Treasure Map
The best odds come from a Legendary Treasure Map, which you can pick up at Feybreak Sea Bases. Once you follow the map and dig up the treasure spot, there is a 0.297% chance the loot includes the Legendary Combat SMG Schematic.
Sunreach chests
You can also pull the schematic from treasure chests found across Sunreach. Each qualifying chest has a 0.094% chance to contain it, so clearing the chest routes in the area repeatedly is the way to farm this source.
Sunreach Skies Dungeon
The third source is the Sunreach Skies Dungeon. Open the chests inside the dungeon and the schematic has a 0.094% chance to appear per chest. Running the dungeon on repeat lets you stack attempts alongside other dungeon loot.
Crafting materials and level requirement
Once the schematic is in hand, you need Level 68 and an Ancient Workbench to build the weapon. The full material cost is heavy, so stockpile the resources before you start.
| Weapon | Materials |
|---|---|
 Legendary Combat SMG | Soralite Ingot x100 Carbon Fiber x60 Cryogenic Coolant x40 Ancient Civilization Parts x9 AI Core x8 |
| Required Level | Lv. 68 |
| Crafting Workbench | Ancient Workbench |
Note: The craft option only shows up when the schematic is sitting in your inventory. If you leave it in a storage chest, the Legendary Combat SMG will not appear as a craftable item at the Ancient Workbench.
Legendary vs regular Combat SMG stats
The Legendary version is a straight upgrade over the common Combat SMG. It roughly doubles both attack and durability while adding to the magazine size, which makes the resource cost worthwhile if you rely on the weapon.
| Stat | Legendary | Regular |
|---|---|---|
| Attack | 1587 | 907 |
| Max Ammo | 50 | 42 |
| Durability | 32000 | 8000 |
Because the drop rates are so low, the fastest path is to farm the source you already have easy access to. Feybreak Sea Bases feed the Legendary Treasure Map route, while Sunreach players can grind the surface chests and the Sunreach Skies Dungeon in the same trips. Keep the schematic on you, hit Level 68, and the Ancient Workbench will let you finish the craft.
