Developer comments: Several of Sigma's items and powers have proved too situational and we're giving them a tune-up. Additionally, his Beam counter item should now be more effective against other Tanks on the roster (looking at you, Reinhardt).

Developer Comments: Sigma is going through a series of balance updates aimed at smoothing out his overall performance. One of his toughest matchups has been against brawlers who can charge in and overwhelm him. This update is part of the ongoing improvements to give Sigma more tools to hold his ground and perform better in those high-pressure encounters.
Zero Gravity - Power
- Added: While flying, gain 10% Damage Reduction.
The Harness – Epic Ability Hero Item
- Added: +15% Ability Lifesteal.
8/7/2025
Developer Comment: Sigma’s barrier wasn’t scaling well into the late game, often feeling too fragile compared to the pressure he’s expected to absorb. We’ve increased its health to give it more staying power as fights become more intense. Additionally, Accretion focused builds have been underperforming, largely due to the ability’s slower cadence in fast paced brawls. With a cooldown buff, Accretion should now be more responsive and impactful! Especially in late game teamfights where frequent crowd control can shift momentum.
- Increased Barrier Health Scalar to 150% (Up from 100%). Barriers now get a bigger health boost from the money you earn.
Hyperloop - Power
- Increased Cooldown Reduction to 0.8s (Up from 0.5s).
Singularity - Power
- Increased Splash Damage to 75% (Up from 25%).

Levitation
- Jump can now be held down to hover.
4/1/2025
Developer Comments: Sigma's realized he was not abiding by Newton's third law of motion, so he figures by deflecting the projectiles he blocks with Kinetic Grasp would make him a more psychics law abiding citizen.
Kinetic Grasp
- Deflects projectiles instead of absorbing them.
- Sigma gains free flight during Kinetic Grasp.
2/18/2025
Kinetic Cycle
- Absorbing projectiles with Kinetic Grasp also reduces Accretion's cooldown.
Massive Impact
- Accretion's knockdown duration increases to up to 3 seconds based on travel distance.
Hyper Strike
- Every 5 direct hits with Hyperspheres, your next successful Quick Melee levitates and knocks away enemies.
Levitation
- Activate and hold Double Jump to briefly levitate upward.
12/17/2024
- Base shield health reduced from 275 to 250.
Experimental Barrier
- Recharge rate increased from 85 to 100 health per second.
Accretion
- Damage reduced from 120 to 100.
9/17/2024
Developer Comment: This shift in damage from the Hyperspheres direct impact into the explosion component is to improve the effectiveness of the airburst explosion when playing at max range and makes it more threatening against tightly grouped enemies.
Hyperspheres
- Impact damage reduced from 25 to 15.
- Explosion damage increased from 30 to 40.
- No longer deals damage to self.
7/5/2024
Developer Comments: Sigma is a tank that does not currently have an issue with survivability when cycling between managing his barrier, Kinetic Grasp, and weapon range. We are however increasing the damage of Accretion to bring back more of the threat it used to pose and increase the satisfaction in landing it, as it also did not benefit from the global increase to projectile sizes.
Accretion
- Impact damage increased from 40 to 80 (120 damage total).
5/24/2024
Developer comments: Our last patch aimed to make some Tank ultimates more forgiving to use during combat. Sigma’s Gravitic Flux can suffer from missing due to slight line of sight checks but we don’t believe this change had proper communication for all instances. We may return to this change for Sigma down the line with updated visuals.
Gravitic Flux
- Gravitic Flux now requires line-of-sight to lift targets again.
5/14/2024
Developer Comment: Similar to how Graviton Surge functions, Gravitic Flux no longer needs line of sight to affect enemy targets in its area. There are a fair amount of counterplay options to deal with this ultimate so we're making it more reliable to grab enemy targets within its area of effect.
Gravitic Flux
- No longer requires line of sight to the center of the effect.
4/16/2024
Developer Comments: This change will improve Sigma's ability to protect allies that are further away from him.
Experimental Barrier
- Movement speed increased from 16.5 to 20 meters per second.
4/1/2024
Developer Comments: Danger! Falling rocks.
Accretion
- Projectile Speed decreased from 37 to 30.
- Projectile Gravity decreased from 18 to 2.
- Pressing the ability button while Accretion is active will cause the rock to crash into the ground. When crashed, it will deal 50 damage in a 4-meter radius and stun anyone damaged.
2/13/2024
- Shields increased from 200 to 275.
12/5/2023
Developer Comments: Sigma has very effective defensive options between his Experimental Barrier and Kinetic Grasp. The barrier regeneration rate is being reduced in order to create more opportunity to attack Sigma directly.
Experimental Barrier
- Regeneration rate reduced from 100 to 85 health per second.
10/31/2023
Added the Hero-Specific Option:
- Rise During Gravitic Flux With Ability 3 - Off by default.
10/10/2023
Added the hero-specific options:
- Experimental Barrier UI - On by default.
- Hide Gravitic Flux Timer - Off by default.
- Gravitic Flux Confirmation Input - Primary Fire by default.
8/10/2023
Developer Comments: Sigma has always had somewhat floatier movement controls than most heroes in order to match his character movement animations. However, this led players to feel like his Tank role passive ability wasn’t reducing the amount he would be knocked back since it took him longer to stop than other tanks. We’ve now adjusted this to the standard hero movement values to make the gameplay interactions feel more consistent.
- Base movement ground deceleration increased to match standard heroes movement.
5/9/2023
Gravitic Flux now automatically casts when the timer runs out
4/11/2023
Developer Comment: Like Roadhog’s Chain Hook, Sigma’s Accretion and primary fire combo can be highly lethal and can feel like a guaranteed kill against 200 health targets. We're reducing the damage slightly to require an additional volley of primary fire but are also increasing the stun duration to provide allies with more opportunity to follow up on successful impacts.
Accretion
- Impact damage reduced from 60 to 40 (80 damage total with explosion)
- Knockdown duration increased from 0.8 to 1.1 seconds
2/7/2023
- Base health in Role Queue modes remains the same at 350
- Base health in non-Role Queue modes reduced from 350 to 200
Gravitic Flux
- Ultimate cost increased 7%
