Combat SMG
Weapon · WeaponAssaultRifle4★A submachine gun forged from Soralite Ingots. The upgraded magazine and ammunition put more weight behind its suppression.
Combat SMG is 26th of 70 assault rifles by attack, at 1,587 against the 15,000 of Charge Rifle.
No recipe takes it as an ingredient. Whatever you build is the finished article, so there is no reason to hoard spares.
Details
At 15 weight each it eats carry capacity fast, so bring a mount or park a chest nearby. At 3,398,060 gold it is worth real money to a merchant.

Where to Find Combat SMG
The recipe is not on the Technology tree — it is locked behind a schematic you have to find first. The best single source is treasure map digs (tier 5) at 0.3% per container, and the table below lists every tier and where each one drops.
The Feybreak sea base camp is really two loot pools, and only one of them knows this gun exists. The ordinary crates scattered through the camp carry all four grades — 17.66% for Schematic 1, 3.53% for Schematic 2, 0.71% for Schematic 3 and 0.14% for the Legendary Schematic 4 — while the stash the camp boss stands over holds a completely different weapon list (Laser Sword, Heavy Assault Rifle, Tactical Grenade Launcher) and never rolls an SMG schematic at any grade. Clear the crates for the gun; the boss is a separate errand.
That errand is still the one to run, because the boss stash hands over a tier 5 treasure map on every clear with no roll attached, and a tier 5 dig is the best single shot at the Legendary copy anywhere in the game at 0.297%. One trip out to the camp therefore stocks both routes at once — crates for direct pulls, boss for the map that feeds the better one. Camp bosses are the whole map supply, and four of them never miss: the sea base camps off Feybreak and Sakurajima, and the land camps on Sunreach Isle, each hand over one tier 5 map per clear, with ordinary Sakurajima camp bosses at 50%. Everything else is scraps by comparison — 10.1% from a technology-book stand in the Viking ruins, 5% from an ordinary chest on Sunreach or Feybreak. So the maps come from the same kind of clear you are already doing for the crates.
Five copies of any grade fuse into one of the next at the Ancient Workbench, so the Legendary line on each pool badly undersells what a container is worth. Counted in finished Legendaries per open: Feybreak sea base crates 0.565%, near 177 crates; tier 5 digs 0.520%, near 192; Sunreach camp crates 0.493%, near 203; Sunreach treasure chests 0.375%, near 267; ordinary Sunreach fishing 0.353%, near 283; plain Sunreach chests 0.244%, near 409; and fishing the Sunreach treasure spots 0.083%, near 1,209 — the one route on the list that is actively a waste of an evening. Six of the seven space their four grades exactly five-to-one, which is precisely what fusion charges, so on those it makes no difference which grade you pull. The dig pool is the exception: it drops Schematic 1 entirely and steps its three grades only two and a half times apart, so it is the route that gets you there without banking hundreds of low copies.
Using Combat SMG Well
The eight AI Cores are most of the real bill and none of it is on the recipe. Each core is ten Soralite Ingots, so the true ingot count is 180 rather than the 100 shown — 360 Soralite and 360 Pure Quartz through an Ancient Furnace before the Workbench sees any of it. Each core also wants five Computers, and forty Computers cost two Carbon Fiber apiece, pushing that line to 140 against the 60 listed, plus 80 Bio Batteries, 80 Circuit Boards and 120 Plasteel that appear nowhere on the sheet. Sixteen Thermal Cores and eight Ancient Civilization Cores round it out, and that last one is not the same item as the nine Ancient Civilization Parts the gun itself asks for. Cores are built on an Advanced Workshop and Computers on a Production Assembly Line II, so both benches need to be standing before the schematic is worth anything.
Carry the schematic, do not store it. The Legendary build only shows up on the Ancient Workbench menu while the schematic sits in your own pockets, and one left in a base chest quietly drops the recipe back to whatever lower copy you happen to be holding. The Feybreak crate run pays for the trip twice over on this front as well: alongside the schematics, those same crates drop 10 to 15 rounds of Combat SMG Ammo about 12% of the time, and that ammo is Ancient Workbench work too, so a camp circuit keeps the magazine fed while you wait on the schematic.
Every Tier of Combat SMG
The same piece exists at 5 rarities, and the gap is not cosmetic: attack runs 907 to 1587, a 1.7x swing. Which one you end up with is decided by the rarity of the schematic you built from, not by the recipe — so a legendary copy of this is worth more than the next item up built from a common one.
| Rarity | Item | Attack | Durability |
|---|---|---|---|
| 0★ | Combat SMG | 907 | 8000 |
| 1★ | Combat SMG | 1088 | 12000 |
| 2★ | Combat SMG | 1224 | 16000 |
| 3★ | Combat SMG | 1360 | 24000 |
| 4★ | Combat SMG (this one) | 1587 | 32000 |
Ammunition Combat SMG Uses
Combat SMG fires Combat SMG Ammo, and nothing else — running dry mid-fight is the usual way this weapon lets you down, so keep the recipe unlocked before you rely on it.
| Ammo | Yield | Craft cost |
|---|---|---|
| ×20 | Soralite Ingot ×2, Gunpowder ×6 |
Schematics That Unlock Combat SMG
The Technology tree hands you the plain Combat SMG at level 68 for 4 Technology points, but nothing above that base version — the rarer builds are schematic-only. One schematic grants the recipe, and they are world loot — chests, boss Pals and the late-game pools — rather than anything you research. Higher-rarity copies of the same schematic raise the quality of what you end up crafting.
Fastest route. The fastest route is sea base enemy camp loot in the Feybreak, and the reason is the ladder rather than the top rung: that pool stocks every tier, so the common copies it hands you fuse upward into the one you want. Counting them, a top-tier Combat SMG schematic works out at roughly 177 containers against the 337 the 4★ drop rate alone suggests. Spare low tiers are progress, not clutter. Schematics fuse five-to-one, so a lower tier with better odds can beat the top tier outright. Counts are containers of that source, not time.
| Schematic | Rarity | Where it comes from |
|---|---|---|
| 4★ | Treasure map digs (tier 5), Feybreak sea base camp loot, Sunreach Isle camp loot +4 more — best 0.3% (grade 5/6) |
Alternatives and Upgrades
Musket sits just above it at 1,600 attack — only 13 more, close enough that it is a sidegrade rather than an upgrade. The next real step is Single-Shot Rifle at 1,650; below it is Laser Rifle at 1,562.
