Step-by-step guide

Everything you need to get it into your arsenal, in order.

1. Get the blueprint

   Buy the blueprint from the in-game Market for 15,000 credits.

   The built weapon also sells for 250 platinum on the Market (paid shortcut, not needed).

2. Craft the sub-components

   • 
     Forma Foundry cost: 35,000 credits · Build time: 23h Morphics ×1 · Neural Sensors ×1 · Neurodes ×1 · Orokin Cell ×1

3. Gather the resources

   • Oxium ×3,500 Dropped by Oxium Ospreys (Corpus) — plentiful in Corpus Defense/Interception.
   • Salvage ×6,000 Mars · Jupiter · Sedna · Kuva Fortress
   • Tellurium ×5 Uranus · Kuva Fortress On Uranus it mostly drops in the underwater (Archwing) missions.

   Total resource list (sub-recipes included)

   • Salvage ×6,000 Mars · Jupiter · Sedna · Kuva Fortress
   • Oxium ×3,500
   • Tellurium ×5 Uranus · Kuva Fortress
   • Morphics ×1 Mercury · Mars · Phobos · Europa · Pluto
   • Neural Sensors ×1 Jupiter · Kuva Fortress
   • Neurodes ×1 Earth · Lua · Deimos · Eris
   • Orokin Cell ×1 Ceres · Saturn · Deimos

   • Salvage 6,000 · 63%
   • Oxium 3,500 · 37%
   • Tellurium 5 · 0%
   • Morphics 1 · 0%
   • Neural Sensors 1 · 0%
   • Neurodes 1 · 0%

4. Craft it in the foundry

   Foundry cost: 65,000 credits

   Build time: 1d (24h)

   Claim it and equip it. Done, Tenno.

Farming assumes a radshare squad for relics and the planner’s per-mission timings (estimated/derived, labeled on each page). The foundry runs on its own: you can play meanwhile.
