Best Roberto Build Megabonk – Full Guide (Tested 2025)
Roberto was released yesterday on Megabonk’s Spooky Update, and I’ve spent countless hours testing builds to see what he is made of. This floating ghost of a character is for savvy players who know how to exploit his Hoarder passive.
BRIEF SUMMARY: Roberto wants Luck Tome first, Aura for staying alive, and Size Tome to reach with Scythe. Rush HP items such as Chonkplate early. Learn how to float so you can kite enemies and spawn their free chests.
Understanding Roberto’s Kit in Megabonk
Roberto begins with the Scythe weapon — a 360-degree slashing tool that attacks anything and everything in the vicinity. It’s projectile-based, has good base attack speed and damage.
Here’s what makes Roberto unique. His Hoarder passive spawns a free chest every 60 seconds. This becomes 120 seconds as your level grows. The more chests looted, the more items acquired, which means quicker power spikes.
The floating ability is game-changing. You can bunny-hop around maps to evade attacks and reposition during boss fights.
The Issue: Roberto’s base HP is very low. Make one early game mistake, and you’re at the menu. This build solves that weakness.
The Verified Floaty Killer Build
This setup made my Roberto runs go from Tier 1 struggling to like several Tier 3 clears, consistently. I have tried more than 15 of them now, and this setup does win.
Best Weapons for Roberto
| Weapon | Priority | Why It Works |
|---|---|---|
| Scythe (Starter) | Core | Your damage core. Upgrade with Damage, Size, Quantity, and Cooldown stats. The preceding attack from killing Elite Enemies annihilates bosses. |
| Aura | Must-Have | Non-negotiable. This forms a damage ring around Roberto and scales with Size modifiers. It was my run saver for so many early-to-mid game swarms. |
| Bone or Revolver | Pick One | Bone jumps from enemy to enemy for crowd control. Revolver can just pump out serious single-target damage with bounce mechanics. Both work. |
| Lightning Staff or Blood Magic | Flexible | Depends on your RNG. Once upgraded, Lightning is an AoE beast. Blood Magic scales slower but is a source of HP stacking. |
Essential Tomes for Maximum Impact
| Tome | Priority | Purpose |
|---|---|---|
| Luck Tome | FIRST | You’re unlocking more chests than any other character, so it’s the quality that counts. I had started to get Legendaries before clearing Tier 1. |
| Size Tome | Mandatory | The Scythe is trash without it. Size also increases Aura’s range, making you a walking field of destruction. |
| Damage or Quantity Tome | High | I like the Damage for great DPS. Quantity works when stacking your projectile-based weapons like a Revolver. |
| Agility or Cooldown Tome | Situational | If you come across Feathers and Turbo Socks early, skip Agility in favor of Cooldown to speed up your attacks. Otherwise, Agility improves your kiting. |
Priority Items That Saved My Runs
| Item | Effect | Why You Need It |
|---|---|---|
| Chonkplate | HP Boost | Your first HP item to get. Roberto needs all the health he can get. |
| Feathers | Float Enhancement | Great upgrade to floating that also increases float time. You’ll be dodging boss attacks as if they are in slow motion. |
| Holy Book | Healing | Provides sustenance as well as healing. Essential for lengthy Tier 3 runs. |
| Overpowered Lamp | Auto-Damage | Kills everything without aiming. Perfect for Roberto’s kiting playstyle. |
| Old Mask | Elite Spawns | Increase the amount of Elites that spawn, thus allowing you to charge your Scythe at a faster pace. |
| Sucky Magnet | Quality of Life | Attracts XP crystals to you. The less time you spend repositioning, the more time you can spend delivering damage. |
How to Unlock Roberto in Megabonk
You are not allowed to play Roberto without these steps first.
1: Open the new Graveyard map and kill Big Bob to get the Scythe.
2: Grab the 4 Crypt Keys from the Coffin Bosses around the map.</p>
3: Go into the Second Crypt and spawn Spooky Steve with the keys.</p>
4 :Defeat Spooky Steve. Roberto is unlocked in the Unlocks menu for purchase.
Pro tip: Bring a tanky character, like Sir Oofie, if you’re trying your first Spooky Steve. He’s tough.
Advanced Playstyle Tips
Master the float-kite technique. Jump, press space while opening chests, and you’ll mega-jump into the air away from danger.
Uncheck low-value items in the Toggler menu. While you have Luck Tome active, only Epic and Legendary drops will be visible.
Camp around the spawns of Elite Enemies. Special attack of your Scythe charges from Elite kills and does significant AOE damage.
Early game focus: Stay alive. Do not hunt for kills – let Aura do that as you dodge out of her way.
Late game focus: Build attack speed and cooldown. Once survivability is figured out, Roberto becomes a DPS machine.
Why This Build Dominates
Items are the gasoline that fuels any Megabonk run, and Roberto has more items than anyone. The passive Hoarder is responsible for the 10-15 additional chests per run.
With Luck Tome, those chests will drop world-shattering items. Before the boss, I always had 3-4 Legendaries.
Size Tome takes away Scythe’s inherent weakness—range. Coupled with Aura, you become a giant damage zone that melts waves.
The build scales exponentially. More chests → better loot → faster clears → more XP → more chest spawns. It’s a perfect feedback loop.
Final Verdict on Roberto
A-tier in my testing, Roberto. He is very frail, non-beginner-friendly at first, but once you understand how his kit works, he becomes a monster.
The floating mechanic takes practice. You’re going to die several times learning the correct positioning for it. That’s normal.
This build is effective as it gets around Roberto’s survivability issue early, and then takes advantage of his Hoarder passive for a monstrous mid-game spike.
If you like high-mobility characters with tactical depth, Roberto has that. The learning curve pays dividends with some of the best late-game runs this side of Megabonk.
