Multi, the modular combat robot in Risk of Rain 2, is one of the most versatile survivors in the game. With multiple weapon loadouts and a high skill ceiling, Multi can adapt to almost any situation. This guide covers advanced strategies and builds to unlock his full destructive potential.

1. Double Rebar Puncher (The Rebar Cheese Build)

Core Setup:

• Primary Weapons: Double Rebar Punchers (main + alternate)
• Special Ability: Retool
• Key Items: Soldier’s Syringe, Mocha

How It Works:
The Rebar Puncher has a long cooldown between shots, but using Retool lets you instantly switch weapons and fire again. By alternating rapidly between the two Rebars, you effectively double your fire rate.

Execution Tip:
Bind Retool to a comfortable key (e.g., E), and alternate it with your attack button for a rhythm of rapid-fire high-damage shots.

Enhance With:

• Soldier’s Syringe / Mocha: Faster swap and reload cycles
• Crowbar: Amplify damage to high-HP enemies

2. Mags and Frags (Blast Canister Spam)

Core Setup:

• Secondary Skill: Blast Canister
• Special Ability: Power Mode
• Key Items: Backup Magazines

How It Works:
Power Mode allows you to dual-wield weapons and resets Blast Canister’s cooldown when toggled. Stacking Backup Magazines gives you multiple charges per cycle.

Execution Steps:

1. Activate Power Mode and spam all Blast Canisters.
2. Exit Power Mode to reset their cooldown.
3. Repeat the cycle.

Best For:
Crowd control, stun-locking elite enemies, and chaining AoE disruption.

3. The S-Slicer (Hyper Armor Build)

Core Setup:

• Utility Skill: Transport Mode Dash
• Special Ability: Power Mode

How It Works:
Multi gains hyper armor (reduced knockback and flinch) while dashing or in Power Mode. This lets you tank burst damage or survive long falls.

Use Cases:

• Mitigate Fall Damage: Dash just before landing.
• Aggressive Engagements: Dash into close-range fights with dual-wield active.

Complement With:

• Infusion / Tougher Times: Sustain
• Paul’s Goat Hoof: Speed to reposition during brawls

4. Nailway to Heaven (Construction Site Build)

Core Setup:

• Primary Weapons: Dual Nail Guns
• Special Ability: Power Mode
• Key Items: Soldier’s Syringe, Tri-Tip Dagger, Crit Glasses

How It Works:
Stack attack speed and on-hit effects for a barrage of bullets. The Nail Gun’s burst fire (when you release the trigger) can even launch you across the map when stacked with enough Syringes.

Advanced Tip:
Stack 30+ Syringes and use the burst fire to create recoil-propelled movement. It’s chaotic, but hilariously effective.

5. Mr. Roboto (Band Synergy Build)

Core Setup:

• High-Damage Moves: Rebar Puncher, Utility Dash
• Key Items: Runald’s Band, Kjaro’s Band

How It Works:
Bands trigger on high single-hit damage. The Rebar Puncher reliably procs them, but even Multi’s dash can trigger band explosions if it hits with enough force.

Tips:

• Use dash against elites to proc bands mid-fight.
• Stack cooldown reduction and crit for frequent procs.

Final Thoughts

Multi is a mechanical menace when used correctly. Whether you’re launching rebar rods at light speed, bouncing across the map with nail guns, or stunning entire hordes with canisters, there’s a build for every playstyle.

Experiment, stack intelligently, and adapt to the RNG. With the right setup, Multi can carry you deep into Monsoon and beyond.

Domo arigato, Mr. Roboto. 🔧
