Countering Sigma Part 1

This loadout is specifically designed to counter [Sigma] , and it branches into two distinct variations:

Type 1: If [Sigma] builds into " [Trinisphere] " for high damage and attack speed, combined with " [Philharmonic Fortitude] " and " [Orbital Barrier] " for sustained healing and long lasting barriers then here are the powers I recommend selecting in response:

" [Spynstem Update] "

This power allows you to effectively deny [Sigma] from doing anything to endanger your teammates. At the same time, it not only boosts your "Terra Surge", but also reflects damage back to his barrier and his team.

" [Centripetal Charge] "

This power works exceptionally well against [Sigma] due to his limited mobility, It helps you build up "Terra Surge" more quickly, allowing you to slow him down and give your team the opening to eliminate him.

Not only that Orisa "Terra Surge" can break the [Sigma] barrier leaving him completely exposed.

"Centripetal Charge" also acts as a backup tool by granting an emergency "Fortify" when needed, helping you stay grounded. From there, it’s on you to follow up with a well placed "Energy Javelin" to interrupt [Sigma] "Gravitic Flux". At close range, it’s a hard shot to miss.

Final Two Power Picks – Situational Choices

Your last two power slots should always be chosen based on what your team needs most at that stage of the match. Here's how to assess your options:

🔹 Need More Protection from Ranged Threats or Sigma’s Accretion? If your team is struggling against hitscan enemies or needs a way to block "Accretion", consider picking " [Shield Divergence] ". It offers excellent utility for protecting teammates during critical engagements.

🔹 Struggling with Healing or Taking Too Much Damage? Choose " [Restortify] ", especially when combined with " [Efi’s Theorem] " and " [Ogundimu Reduction Field] ". This setup improves your survivability and helps you absorb heavy pressure.

However, be cautious this combination is designed for sustaining damage, not for recklessly diving into the enemy backline. You're tougher, not invincible.

🔹 Team Holding Well? Go Offensive. If your team can hold their own and doesn’t need constant support, you can shift toward extra damage output with " [Supercharger] ". It’s effective in certain situations, though I personally use it less often and don’t have as much feedback on it.

Bonus Synergy: [Ride with Me] + [Hooves of Steel]

I’ve found that " [Ride with Me] " and " [Hooves of Steel] " create a powerful synergy for team sustainability:

🔸 " [Hooves of Steel] " boosts your base health and heals you after "Fortify" ends. This increased health stays active until your next Fortify is cast.

🔸 With " [Ride with Me] ", your next "Fortify" grants overhealth to allies in your line of sight.

🛠️ How it works: The more damage you absorb, the more your health scales up. When "Fortify" is reactivated, that larger health pool results in greater overhealth shared with your teammates. This creates a natural rhythm of tanking, healing, and team reinforcement all based on timing and positioning.

Example: With [Hooves of Steel] Orisa’s base health increased to 1663 from taking damage.

When activating Fortify with [Ride with Me] , she granted 221 Overhealth to all allies in line of sight. (Note: Allies behind walls won't receive overhealth.)

It’s an excellent choice for coordinated teams and prolonged teamfights where sustained frontline pressure is critical.
