Overwatch Stadium: Best Sigma, Junkrat and Zenyatta builds in 2025

After a critically acclaimed debut, the Overwatch 2 Stadium mode took a little bit of a hit when Freja was released in a very overpowered state. After some tuning, she was reigned back in, and a lesson was learned. This is the reason why the three new characters just added to the mode (Sigma, Junkrat and Zenyatta) don’t feel as overpowered as new releases normally do in Blizzard’s hero shooter.

What the developers achieved with their new balancing philosophy, however, is true freedom of choice when building a character. Our previous build guides for Tanks, DPS, and Supports had clear winners in terms of strategies; now, each hero has at least two full sets of powers worth experimenting with. Despite the shift, there’s still a little advantage to be gained by the more knowledgeable players who can manage cooldowns, flanks, and the many different situations that require solid Overwatch Stadium builds. 

While there are no publicly available stats to prove which builds are technically the best, this list is based on extensive testing as of June 2025, along with the author’s own experience and judgment. We’ve included multiple options for Overwatch Stadium build upgrades for each of the three new characters, and we recommend experimentation. 

Why Sigma: In the current meta, Sigma is the only tank that can easily be built both defensively and offensively.

Our Overwatch Stadium build guide keeps things simple but effective. Starting with Philharmonic Fortitude (which gives your barrier constant health regeneration), you then add Orbital Barrier to get a mini shield that orbits you, and Event Horizon to convert damage absorbed with Kinetic Grasp into barrier health. You then proceed to invest all your money in survivability and cooldown reduction to become resilient and immovable.

By utilising Overwatch Stadium upgrades, you can further optimise, as our second build shows. Starting with Trinisphere, we’re giving Sigma a third projectile, then with Apogee Alignment, we’re generating two more Hyperpheres on ability usage to discourage adversaries from coming too close. Then, with Symphonic Syzygy, we’re converting Kinetic Graps usage into a power-up for up to 40% more temporary attack speed. Item wise we’re investing in weapon power, and gameplay-wise wise it’s imperative not to push too hard at the risk of endangering the supports. With this build, Sigma can even help with flankers, but you should not get distracted by them and focus on breaking the enemy front line. 

To try this build, use this code: NMYH1 in the “import build” section of the Stadium practice range.

Why Junkrat: Junkrat is chaos incarnate, but with a few well-placed items, it’s possible to hone in on his destructive potential.

A Junkrat Overwatch Stadium build can be distinct in two different ways, with some flavouring in the middle. One is betting everything on his abilities: traps and concussion mines, the other is to power up his Frag Launcher to unreasonable metrics. For the mine-focused build, we’re starting with Hop Boom to multiply explosions on site, and then Rainin Lead to drop bombs while airborne. Then we close the build with Soot Shaker for extra ammo and attack speed, and Rip Roll for a more efficient ultimate. The items section has everything invested in Ability Power.

Our second Overwatch Stadium build guide for Junkrat requires a little more knowledge of the character but rewards with incredible destructive potential. Starting off with Big Bang, our playstile is aiming at maximising bounces to cause mayhem on the objective. Then it’s 2 Frag 2 Frurious for more bombs, and Soot Shaker to reload on Concussive Mine detonation. You can round this build out with Bingo! or Bango! to start getting better at direct hits and slowly transition your Junkrat into a medium-range sniper menace. Item Wise we’re starting with more bounce distance (to substitute when you get better), lifesteal, and damage against shield or armour. Then we go heavy on cooldown reduction and weapon damage. 

To try this build, use this code: 109WR in the “import build” section of the Stadium practice range.

Why Zenyatta: Zenyatta is the support to pick for big damage, that’s it.

There are great healers in Stadium, and Zenyatta is not one of them. He is an amazing DPS, though, so we’re going to build him that way while maximising his transcendence output for intense teamfight with our Zenyatta Stadium build. His most potent power is Discord Fever, which deals 50 ability damage to the target that Discord Orb is on, and it scales rapidly. Then we’re investing in Instant Karma for survivability (which we’re going to need a lot of) to have some damage we take refunded.

Then we could go even harder on the damage with Disco Inferno, which detonates the orb on critical hits, or have more independence with Gotta Have Faith, so more off-angles are available without losing the Harmony Orb we placed on the tank. Item-wise, in the purple section, we’re investing in Transcendence to increase survivability and accelerate allied cooldowns. You can substitute this last one with Phantasmic Flux to gain overhealth for more security while flanking. The versatility of Zenyatta and the two mentioned above shows how far the Overwatch Stadium roadmap has come in its short time since launch. 

To try this build, use this code: A6WY1 in the “import build” section of the Stadium practice range.

The three new additions to the Stadium mode are varied and full of options. Try our builds with their respective codes to see just how much damage Sigma and Zenyatta can do and how versatile Junkrat can be, shifting from area denial to single-target damage. The community laments the addition of two crowd control capable targets, but these heroes bring even more depth and variables to the game mode, contributing to its overall health. We hope that these Overwatch Stadium tips & tricks for the three new characters will help you get ahead.
