What a workshop upgrade set is

Every workshop station levels up with a fixed list of items. A set here is everything for one step, like Gunsmith 1 → 2, so you can level the station the moment you're back from the raid.

Single parts

Short of one or two items? The single parts cover every upgrade item we don't sell elsewhere, from Bully Fragmenters to ARC Data Modules, and each one says which upgrade needs it. Basic and refined materials are on the Materials page.

Why buy upgrades instead of farming them

Upgrade items drop from specific ARC and turn up while scavenging, and the higher levels need parts from tougher enemies. Buying the set levels the station now, so you can craft better gear sooner.
