Best Overwatch 2 Stadium Sigma Build Season 17: Almighty Orbit

Publish Date: June 25, 2025

Season 17 of Overwatch 2 Stadium has introduced Sigma to the mix, which means it is time for us to create our best build for the newly added hero. With some unique Powers that create orbiting items around Sigma, this felt like a perfect opportunity to turn this usually poke hero into a brawling menace in this Almighty Orbit build.

Build Priorities & Strategy

This build is designed to keep you in the fray for long periods of time, stay healthy, and cycle cooldowns. So, we look to focus on items that give you more ability to survive and keep your shields as strong as possible. Sigma is usually a hero that likes to poke and stay far away, but this Sigma build has you doing the opposite and staying primarily in the frontline.

Build Pros & Cons

Pros:

  • Great ability to mitigate damage and cycle cooldowns
  • Great space-taking and zoning

Cons:

  • Orbiting shield and spheres can be a bit unpredictable
  • Some DPS sacrificed for tankiness
