Gyromag, Atmo and Repeller Systems (2026): Where to Get Them and What They Build
Profit-Taker phases, Little Duck prices, and Toroids turned into standing
Last Updated on September 30, 2026
The short answer
The only drops left are from the Profit-Taker heist: every phase can pay all three, and Phase 2 is the fastest to repeat. You can also buy them from Little Duck: Gyromag for 1,000 standing, Atmo for 2,500, Repeller for 5,000. Toroids turn into that standing at 1,000 each, so Toroids work as a currency for these parts.

How to get them
- Finish the Vox Solaris quest and The War Within, then talk to Little Duck as your Operator or Drifter.
- Rank 1 (Operative) asks for 1 each of a Vega, Calda and Sola Toroid. Buy Gyromag Systems for 1,000 standing.
- Rank 2 (Agent) asks for 1 Gyromag Systems and 1 Vega Toroid. Buy Atmo Systems for 2,500 standing.
- Rank 3 (Hand) asks for 1 Atmo Systems and 1 Calda Toroid. Buy Repeller Systems for 5,000 standing.
- Rank 4 (Instrument) asks for 1 Repeller Systems and 1 Sola Toroid.
- To stock up, repeat Profit-Taker Phase 2. Every phase drops the systems with the same odds, and Phase 2 is the quickest.
- Turn spare Toroids into standing at Little Duck (1,000 each) and buy the rest. That is 1 Toroid per Gyromag, 2.5 per Atmo, 5 per Repeller.
What no longer drops these
- Fortuna bounties no longer list these parts. The official drop table shows them only in the Profit-Taker heist phases.
- Old advice to farm bounty tiers for Gyromag is stale: use the heist or the vendor.
Tips that save runs
- The rank-up sacrifice for each rank is only one of each part now, since Update 35.1. You do not need to farm dozens to rank.
- Phase 1 to 3 rewards use the same odds, so the shortest phase is the best farm. Phase 4 has a slightly better roll and always drops a Crisma Toroid.
- Buying is cheaper than farming when you only need a handful, because the standing price is small.
Mistakes that waste runs
- Farming old Fortuna bounty tiers. Only the Profit-Taker phases drop them now.
- Ranking before buying. The systems are a rank-up sacrifice, so buy them one rank early.
- Going to Little Duck in a Warframe. She only talks to your Operator or Drifter.
