If you’ve been grinding in Steal a Brainrot trying to collect the absolute rarest units, you’ve probably heard whispers about Los Sweethearts. This unit isn’t just a status symbol; it’s a game-changer with stats that can clear entire waves of enemies or dominate PvP lobbies. But here’s the catch: you won’t find Los Sweethearts spawning naturally on the map. You have to craft it.

I’ve spent hours testing combinations, losing units to failed fusions, and scouring the official Discord to bring you the exact, verified recipe. In this guide, I’ll break down exactly how to get Los Sweethearts, the ingredients you need, and the strategy to maximize your fusion success rate.

How to Get Los Sweethearts in Steal a Brainrot?

Getting Los Sweethearts requires understanding the Fusion System. Unlike common units that spawn on the map every few minutes, Secret units like Los Sweethearts are created by combining two specific high-tier units at a Fusion Shrine.

Here is a quick overview of what you are up against:

Requirement	Details	Difficulty
Primary Ingredient 1	Los (Mythic/High-tier Unit)	Hard (Low Spawn Rate)
Primary Ingredient 2	Sweetheart (Rare/Event Unit)	Medium (Trade/Spawn)
Fusion Station	Secret Fusion Altar	Easy to locate
Success Rate	Base ~20% (increased with Luck)	Requires Luck Gamepass/Potions
Minimum Level	Level 25+ Recommended	Medium

Prerequisites for Fusion

Before you even think about fusing, you need to meet a few requirements. Trust me, trying to fuse without these is a waste of time and resources.

Unlock the Fusion Area: In most Steal a Brainrot maps, the fusion area is located in the lobby or behind the main shop. You usually need to be at least Level 10 to access it.
The Ingredients: You must possess both a “Los” unit and a “Sweetheart” unit. These are not the same thing.
Currency: Fusions often cost in-game currency (Brains or Coins). Have at least 5,000 ready.

The Secret Fuse Recipe for Los Sweethearts

Alright, let’s get to the meat of the guide. The rumor mill is full of fake recipes, but I’ve verified this combination on the official Steal a Brainrot Trello and community servers.

The Recipe:

Los + Sweetheart = Los Sweethearts

It sounds simple, but obtaining the ingredients is where the grind lies.

Ingredient 1: How to Get ‘Los’

Los is a high-tier unit, often classified as Mythic or Secret depending on the current patch.

Spawn Location: Los typically spawns in the “Dark Web” or “Basement” area of the map.
Spawn Time: Every 30 to 45 minutes.
Strategy: You will be competing with other players. I recommend server hopping until you find a less populated server. Use a speed unit to get to the spawn point quickly.
Alternative: You can trade for Los. Check out our guide on How to Trade in Steal a Brainrot for tips on striking a deal without getting scammed.

Ingredient 2: How to Get ‘Sweetheart’

Sweetheart is usually a limited-time unit or a Rare spawn.

Spawn Location: Spawns near the “Carnival” or “City” zone.
Spawn Time: Every 15 minutes.
Event Method: Sometimes, Sweethearts are obtainable through specific Valentine’s or Anniversary event quests. If the event is over, you will have to trade for this unit.
Trading Value: Expect to pay around 2-3 Legendary units for a Sweetheart if you can’t find a spawn.

Step-by-Step Fusion Process

Once you have both units in your inventory, follow these steps carefully. The fusion process in Steal a Brainrot can be glitchy, so follow the order precisely.

Equip the Units: Do not just leave them in your inventory. Equip the “Los” unit in your first slot and “Sweetheart” in your second slot (or vice versa, order typically doesn’t matter, but being consistent helps avoid UI bugs).
Navigate to the Fusion Altar: Go to the main lobby. Look for the glowing purple/pink beam. This marks the Fusion Altar.
Interact with the Altar: Press ‘E’ (or click) to open the Fusion Menu.
Place the Units:
- Drag Los into the left slot.
- Drag Sweetheart into the right slot.
Check for Buffs: This is crucial. Do not click fuse yet. If you have a “Luck Potion” or a “Fusion Boost,” use it now. This increases your chance of success from roughly 10-20% to upwards of 50%.
Initiate Fusion: Click the “FUSE” button.
Cross Your Fingers: A cutscene will play. If successful, you will hear a distinct “Heartbeat” sound effect, and Los Sweethearts will appear in your inventory.

What if Fusion Fails? (Troubleshooting)

One of the most frustrating mechanics in the game is the chance of failure.

Did you lose your units? In Steal a Brainrot, a failed fusion usually consumes one of the ingredients, not both. Typically, the lower-tier ingredient (Sweetheart) is consumed, and you keep Los.
Bug Check: If the menu glitches and takes both items without giving you the result, join the game’s Discord immediately and open a support ticket. Take a screenshot of your inventory before fusing just in case.

Why You Need Los Sweethearts: Stats & Abilities?

Is the grind worth it? Absolutely. Here is why Los Sweethearts sits at the top of the meta right now.

Damage Output: It has one of the highest DPS (Damage Per Second) in the game, capable of one-shotting “Time Stealers” in the late game.
Ability: “Brainrot Love”: When activated, this ability stuns all enemies in a massive radius for 5 seconds while dealing ticking damage. This is a lifesaver in raids.
Economy: This unit generates passive “Brain” currency faster than almost any other unit, making it essential for AFK farming.

Pro Tips for Farming Ingredients

I’ve learned a few tricks that can save you hours of grinding:

Server Hop Macro: If you are on PC, using a simple auto-clicker to server hop can help you find ingredients faster than camping one server.
Trade Up: Don’t grind for both ingredients. It is often faster to grind a valuable “Trading” unit (like a duplicate Mythic) and trade it for the specific ingredient you need.
Check Private Servers: Some private servers have different spawn timers or fewer players. If you have Robux, buying a private server can give you a monopoly on ingredient spawns.
Follow the Developer: The developer @StealBrainrotDev often drops codes or hints about spawn rate boosts on Twitter.

Common Mistakes to Avoid

Fusing without Luck: The base success rate is abysmal. Never fuse without a Luck Boost active.
Wrong ‘Los’: There are fake variants like “Fake Los” or “Corrupted Los”. Ensure the unit name is exactly “Los”. Fake units will not work in the recipe.
Inventory Space: Make sure you have an open slot in your inventory before fusing. I’ve seen players successfully fuse but lose the unit because their inventory was full.

FAQ’s

Can I get Los Sweethearts from a code?

No. As of March 2026, there are no active codes that give Los Sweethearts directly. Codes usually give currency or lower-tier units. You can check our active codes list here.

Is Los Sweethearts tradeable?

Yes, once you have fused it, you can trade Los Sweethearts. It is currently one of the most valuable units in the trading market, often demanding 3-4 other Mythic units in return.

Do I need a Gamepass to fuse?

No gamepass is required to access the fusion station, but the “2x Fusion Luck” gamepass is highly recommended to save your resources.

What is the spawn rate of Los?

Los spawns every 30-45 minutes with a 1% chance per spawn cycle. It is extremely rare.

Does the event end?

The availability of ingredients like “Sweetheart” can be limited. If “Sweetheart” was part of a Valentine’s event, the spawn might be disabled in the future, making trading the only option. Always check the game’s latest update log.

Conclusion

Securing Los Sweethearts in Steal a Brainrot is no small feat—it is the ultimate flex for dedicated players. The journey involves grinding for the elusive Los unit, hunting down the specific Sweetheart ingredient, and braving the risky fusion RNG. While the process can be grueling, the payoff is massive. With its ability to stun enemies and generate passive currency, Los Sweethearts will likely remain a meta-defining unit for the foreseeable future.

Remember, preparation is key. Don’t risk your hard-earned ingredients without a Luck Boost, and always double-check that you are using the correct units for the recipe.
