Best Rocket Raccoon Build for Marvel Rivals Path to Doomsday: Infinity War Mode

The new Path to Doomsday: Avengers: Infinity War limited-time mode in Marvel Rivals pits six duos against each other as they fight to collect all six Infinity Stones. With upgrades shaping your hero’s abilities as each round progresses, picking the right cards is just as important as knowing when to use your abilities.

On that note, Rocket Raccoon is one of the strongest high-DPS heroes you can pick in this mode, and you won’t be playing him like the support hero you’re used to. While his abilities (and upgrades) might seem a little complicated at first, getting the most out of them is actually quite straightforward once you know which upgrades to pick and how they work together.

With that in mind, here’s the Rocket Raccoon build we recommend if you’re looking to collect all six Infinity Stones in the new 2v2 PvP mode.

Best Upgrade Cards for Rocket Raccoon in Marvel Rivals Infinity War Mode

Our build focuses on Repair Mode spheres, Bombard Mode, and B.R.B. Your goal is to make said spheres follow your target, deal critical damage with your primary attack, and trigger additional damage around your beacon. Prioritize the following cards whenever they appear.

Best Prismatic (Shiny) Enhancement Cards

These cards exponentially improve Rocket’s damage or simply help him survive longer against good opponents. Weakness Insight is the best offensive option for this build, while AP Rounds is particularly useful against enemies with high Damage Reduction:

• Weakness Insight: Critical Damage Multiplier +75%. This works well with Target Sighted, which allows Bombard Mode to deal critical hits against enemies taking continuous damage from a Repair Mode sphere.
• AP Rounds: 60% of damage dealt ignores the target’s Damage Reduction. Pick this against defensive builds.
• Full Refund: Once per round, casting your Ultimate Ability fully recharges it instantly. This gives you another use of your Ultimate.
• All-Rounder: Primary Attack Damage, Ability Damage, Primary Attack Speed, Cooldown Reduction, and Ultimate Ability Charge Rate +15%. A useful upgrade when you want to improve several stats at once.
• Gamma Might: Size +30% and independent Maximum Health +40%. The additional health helps you survive focused attacks.
• Shock-Absorbing Coating: Critical Damage Multiplier taken -50%. Choose this when enemies rely heavily on critical hits.

Best Advanced (Orange) Enhancement Cards

Target Sighted is the most important card in this Rocket Raccoon 2v2 build because it lets every Bombard Mode shot critically hit an enemy taking continuous damage from your spheres. The other cards help you keep those spheres active and deal more damage:

• Target Sighted: When Bombard Mode hits an enemy currently taking continuous damage from a Repair Mode sphere, all hits deal critical damage, regardless of where the shot lands. Get this as early as possible to start melting your target’s HP.
• Bombardment Pull: When Bombard Mode hits an enemy, all other active Repair Mode spheres redirect to track that target. This keeps your damage focused on one opponent.
• Covering Fire: Using Jetpack Dash near a B.R.B. automatically fires multiple Repair Mode spheres backward. After a brief delay, these spheres track the nearest enemy, giving you additional damage.
• EMP Beacon: When Repair Mode spheres are near a B.R.B., they emit a beacon shock at nearby enemies. This adds another source of damage to your build.
• Universal Amp: C.Y.A. can simultaneously link to B.R.B. and enemies. Linking to the beacon amplifies Shock Damage, while linking to an enemy weakens their damage output.
• Beacon Barrier: Generates a spherical barrier centered on B.R.B. and increases its detection frequency. Choose this when you need additional protection around your beacon.

Best Common (Blue) Enhancement Cards

These cards improve the Advanced upgrades above, and you can stack them to strengthen their effects. Once you have enough health and Damage Reduction to survive the round, focus on generating more spheres and improving their damage. Stacking Terminal Damage is particularly important to maximize your damage potential:

• Terminal Damage: Increases the Critical Damage Multiplier when Bombard Mode hits a target marked by a Repair Mode sphere. Stack this to improve your damage when using Target Sighted.
• Sphere Surge: Increases the number of additional Repair Mode spheres generated by Jetpack Dash by one per stack and increases the detection frequency of the spheres’ Shock Field. This makes each dash more useful.
• Sky Full of Spheres: Fires one additional Repair Mode sphere per cast, up to a maximum of 10. More spheres mean more opportunities to damage your target.
• Expanding Orbs: Increases the maximum number of Repair Mode spheres that can exist simultaneously by one per stack and extends their maximum duration. This helps maintain damage between casts.
• Cosmic Router: Improves C.Y.A.’s effects by increasing the Shock Damage boost when linked to a beacon and the Damage Reduction when linked to an enemy. It strengthens both effects of Universal Amp.

Best Universal (Red) Enhancement Cards

Universal cards are available to every hero in this mode. Since this build relies on Repair Mode spheres rather than primary attack damage or your Ultimate, prioritize health and Damage Reduction first. You can also ignore critical hit and Ultimate-focused upgrades:

• Robust Health: Maximum Health +10%. Take this for a straightforward increase to your health pool.
• Resilient Build: Maximum Health +5% and Damage Reduction +5%. This improves your survivability in every fight.
• Thick Skin: Damage Reduction +5%. A useful defensive upgrade when the enemy duo focuses you.
• Swift Casting: Primary Attack Speed +12% and Cooldown Reduction +12%. The cooldown reduction helps you use Jetpack Dash more often.
• Heat Sink: Cooldown Reduction +20%. This is another option for reducing your ability cooldowns.
• Ability Expert: Ability Damage +10% and Cooldown Reduction +10%. Pick this when you want more ability damage alongside shorter cooldowns.

Best Playstyle & Tips for Rocket Raccoon in Marvel Rivals Infinity War Mode

The main thing to remember while playing Rocket Raccoon in this 2v2 PvP mode is that his Repair Mode spheres do not heal you or your teammate here. Instead, they deal continuous damage to nearby enemies. Once you have the necessary Advanced cards, follow this rotation:

• Place B.R.B. near the fight. You want your spheres close enough to the beacon for EMP Beacon and Universal Amp to take effect. Avoid placing it too far away from your opponents!
• Use Jetpack Dash near B.R.B. to activate Covering Fire. The additional spheres will automatically track and home in on nearby enemies.
• Keep firing Repair Mode while using Bombard Mode against the same target. Target Sighted makes your primary shots deal critical damage as long as a sphere is continuously damaging that enemy.
• Pick your target carefully. Bombardment Pull redirects your other active spheres towards the enemy you hit with Bombard Mode, so focus on one opponent instead of spreading your damage across both.
• Stack the right Common cards as the round progresses. Sky Full of Spheres and Expanding Orbs help you maintain pressure, while Terminal Damage increases the critical damage you deal. Don’t neglect health and Damage Reduction if you are struggling to survive!
• Use your Ultimate whenever it is available and useful. Keep moving around the fight, protect your beacon, and work with your teammate to keep opponents within range of your spheres.

Once you have the core Advanced cards, the rotation is straightforward. Keep your beacon near the fight, spawn more spheres with Jetpack Dash while also holding down your secondary attack, and shoot the enemy they are targeting. The biggest challenge is surviving long enough to put the build together, so don’t forget to choose those defensive upgrades whenever you need them.
