  • Shield health reduced from 275 to 250.

Hyper Regeneration – Minor Perk

  • Damage conversion reduced from 40% to 30%.

Sigma remains durable when successfully rotating through his defensive tools. Reducing his shield health lowers his survivability when opponents are able to break through his defenses.

Symphonic Syzygy - Power

  • Damage Absorbed threshold for Attack Speed reduced to 50 (Down from 100).

Experimental Barrier

  • Barrier health reduced from 700 to 650.

Hyper Regeneration – Minor Perk

  • Barrier health conversion rate reduced from 50% to 40%.

Sigma’s ability cycling can make him difficult to break through. Reducing his barrier health and Hyper Regeneration’s effectiveness creates more opportunities to pressure him.

Mass Driver - Power

  • Added: [Experimental Barrier] heals 100 (AP) health when [Accretion] projectile passes through.

Event Horizon - Power

  • Added: [Kinetic Grasp] also gives overhealth to allies in line of sight.

Singularity - Power

  • Added: [Accretion]'s cooldown is reduced by 25% on direct hit.

Apogee Alignment - Power

  • Hypersphere damage decreased from 100% to 50%.

These updates are aimed at pushing Sigma further into a tempo-controlling tank who rewards precision and smart ability timing rather than raw damage stacking. We’re adding more synergy around Accretion to encourage accurate play and give Sigma clearer moments of payoff through healing, cooldown reduction, and team value. Event Horizon expands Kinetic Grasp into a more supportive, frontline-anchoring tool, allowing Sigma to share some of his durability when he commits. At the same time, Apogee Alignment’s damage has been toned down to keep Hypersphere from overshadowing the rest of his kit. Overall, this pass shifts power away from passive damage and into deliberate ability interactions that better define Sigma’s identity in Stadium.

  • Zero Gravity - Power
    • Decreased duration to 1.5s (Down from 4s).
  • Antimatter - Epic Weapon Hero Item
    • Increased cost to 12000 (Up from 10000).
    • Decreased weapon power to 10% (Down from 15%).
  • Velocity Vector - Rare Weapon Hero Item
    • Increased cost to 6000 (Up from 4500).
  • The Harness - Epic Ability Hero Item
    • Decreased cost to 10000 (Down from 11000).

With Sigma’s recent updates to his primary fire, he has been beyond the intended power ceiling. Zero Gravity offered too much uptime and safety, allowing Sigma to disengage or reposition with minimal risk. At the same time, some weapon items were providing strong value for their cost, accelerating his damage curve. These adjustments rein in his mobility and early scaling while rebalancing item costs to better reflect their impact. The Harness receives a small cost reduction to keep ability power builds competitive as other options are tuned down.

Hyperspheres

  • Impact direct damage reduced from 25 to 20.

Hyperspheres

  • Impact direct damage increased from 15 to 25.

Sigma can struggle to secure eliminations in certain matchups. Increasing direct impact damage rewards precision and improves key breakpoints when comboing with the rest of his kit.
