ARC Raiders Expert Weaponsmith: upgrade to IV

ARC Raiders Expert Weaponsmith requires upgrading a weapon to Tier IV. Single source route: complete that upgrade action yourself; the published method distinguishes it from merely receiving a weapon already at Tier IV.

Before spending materials

1. Inspect the weapon's current tier and its upgrade option in Speranza.
2. Read the live material requirements. An older Ferro example is not a verified price list for every current weapon.
3. Reserve those parts on your keep list.
4. Complete the upgrade to IV, confirm the resulting tier and check the platform award.

The published route allows starting with a weapon already at III rather than repeating every earlier step. This is different from assuming a found IV weapon automatically grants an award whose wording names an upgrade.

UNSURE: every current recipe, station gate, cheapest route, current console trigger reliability and reset persistence. Frozen Trail amplification is another progression choice; this page does not substitute an amplification purchase for the stated IV action. Online play is required. Time and numerical difficulty remain unscored; no Hizzle in-game testing.
