Overwatch 2’s Stadium mode is unlike anything we’ve seen in the game so far. It mixes third-person action with a loadout system that feels closer to a hero-based battler than the standard shooter format. In this chaotic arena, healing isn’t enough, the best supports adapt, disrupt, and carry. If you're diving into Stadium and wondering how to get the most out of support heroes like Mercy and Moira, we’ve crafted builds that go beyond basic healing and turn these characters into full-on battlefield tacticians.

Mercy
Mercy isn’t just a pocket healer in Stadium, when built right, she becomes a mobile medic capable of flipping a lost fight in seconds. This build focuses on resurrect utility, enhanced Valkyrie uptime, and keeping your squad buffed and alive.
Power Progression
- Round 1: Renaissance – Activates Valkyrie for 5 seconds after each resurrection.
- Round 3: Crepuscular Circle – Boosts healing and damage for nearby allies during Valkyrie.
- Round 5: First Responder – Grants 250 overhealth to you and your resurrected teammate.
- Round 7: Distortion – Grants 20% Lifesteal to allies you’re boosting.
This combo turns every resurrection into a game-altering event. The overhealth shield buys you time to reposition, while Valkyrie’s activation triggers massive AoE support potential. It’s designed to swing team fights and punish enemy overextensions.

Item Loadout
Item | Type | Role |
Angeleisure Wear | Survival | Boosts passive healing while airborne |
Long Distance Wings | Ability | Extends Guardian Angel range |
Caduceus Ex | Weapon | Enhances staff range and damage boost |
Chain Evoker | Survival | Adds armor and extra ult charge via damage boost |
Martian Mender | Survival | Self-healing at 3% HP per second. |
Resurrection Rangefinder | Ability | Cuts Resurrect cooldown and increases range. |

Mercy becomes nearly untouchable with this setup, flitting across the battlefield, chaining buffs, and staying alive long enough to keep the whole team fighting. Chain Evoker’s armor plus passive healing gives you real staying power in drawn-out rounds.
Moira
Moira excels at pressuring enemies while sustaining her squad, and in Stadium, she transforms into a multitarget threat. This build emphasizes ability power, orb trickery, and enemy debuffing, making her a menace in both healing and damage roles.
Power Progression
- Round 1: Deconstruction – Bonus damage after using Biotic Energy.
- Round 3: Chain Grasp – Biotic Grasp hits multiple enemies for a short time.
- Round 5: Cross-Orbal – Sends a secondary Orb of the opposite type with each use.
- Round 7: Ethereal Excision – Adds critical effects and healing reduction to alt-fire.
Moira can wear down grouped enemies while keeping her team topped up. The orb synergy lets you control space, while the Grasp chains add pressure and utility in brawls. Ethereal Excision is your ace against tanks and entrenched supports.

Item Loadout
Item | Type | Role |
Champion’s Kit | Ability | +40% ability power |
Three-Tap Tommygun | Ability | +10% AP & attack speed, damage boost after using ability |
Mark of the Kitsune | Ability | Grants bonus heal/damage after using ability |
Eye of the Spider | Weapon | Deals more damage to low-HP enemies |
Codebreaker | Ability | Ignores 50% armor, +15% weapon power |
El-Sa’ka Suppressor | Ability | Inflicts healing reduction, triggers critical effects. |

Stacking ability power and status effects, this loadout lets you whittle down tanks and force DPS to retreat. El-Sa’ka Suppressor combos well with Ethereal Excision, turning every secondary fire shot into a mini-execution, especially nasty against sustain-heavy comps.
Stadium mode is an arena where supports can hard-carry games, not just by healing, but by controlling the pace and manipulating the flow of battle with well-planned builds. Mercy provides momentum-shifting utility through smart resurrections, while Moira acts as a disruptive force, splitting enemy focus and punishing poor positioning.
