Target a source pool, not a generic chest
The reference’s v1.0.3 normalized inventory reports 490 schematic items and no schematic rows in its dungeon-end-chest pool. That is a claim about that extraction, not proof that every dungeon reward in every later version is empty. Identify the exact schematic and named pool before repeating a farm.
The dated source census
| Source family | Entries | Unique schematics | Pools |
|---|---|---|---|
| Named chests | 957 | 416 | 23 |
| Enemy camps | 890 | 265 | 36 |
| Fishing | 595 | 284 | 25 |
| Supply drops | 228 | 180 | 8 |
| Oil rigs | 196 | 185 | 6 |
| Recycler | 140 | 28 | 5 |
| Salvage | 26 | 26 | 2 |
| Expeditions | 26 | 5 | 16 |
Progression-first routing
The dated source inventory reports 34 vendor schematics and two fixed Arena first-clear schematic rewards. Those are counts of its reported entries, not proof that every vendor or milestone is available on a later patch. Check a target’s item record for an exact merchant or reward before starting a random farm.
The older article counts 93 Ancient Shrine schematic rewards. The acquired map now reconciles 106 terminals with 92 schematic reward rows, alongside handbooks and implants. Use the actual terminal inventory for its denominator rather than silently treating the older 93 as the pinned map total.
Duplicates and a farm audit
Before using five copies, open the desired output record and confirm its input identity. Collect enough copies of that exact predecessor, check the crafting menu, then inspect the resulting next-tier record. Do not combine different weapon families or assume a tier can be skipped. A crafting work value is not elapsed seconds; the catalog alone does not establish every crafting-station restriction.
For the hunt itself, check the named source pool, chance or fixed reward, and required activity. Save useful duplicates while farming materials for the eventual weapon. Official 1.0.4 changed fishing rewards, so an older fishing census needs a separate later-version check.
Five matching copies advance one schematic tier
All 275 blueprint-to-blueprint upgrade recipes in the pinned v1.0.3 recipe catalog take five copies of one lower-tier schematic and produce one next-tier schematic. This is an exact recipe relationship, not a promise that all 490 schematic items have an upgrade or that any five unrelated schematics can be combined. Keep stacks separated by family and tier.
