There are 11 fusion mods in Mass Effect: Andromeda , and they are unique one-of-a-kind items rather than stackable gear upgrades. They’re obtained from vaults, Architects, a late-game mission reward, and a hidden Havarl task.

How they work

Fusion mods are installed on compatible gear at a loadout station, and each mod gives a strong bonus with a trade-off. In practice, you can use one fusion mod per armor piece that has a fusion slot , so the limit is based on your equipped gear, not on a global cap.

The full count

The known set includes:

  • Shielding.
  • Biotic Mastery.
  • Resistance.
  • Hovering.
  • Rupture.
  • Tech Mastery.
  • Rapid Deployment.
  • Battering.
  • Robotics.
  • Adrenaline.
  • Health.

Quick note

If by “use” you meant “how many can I equip at once,” the answer is limited by how many fusion-slot armor pieces you have equipped, while the total number available in the game is 11.
