Unlike regular fusion machines, the Witch Fuse incorporates Halloween-themed mechanics and offers exclusive mutations and traits that won't be available after the event ends. The machine is located at the center of the map next to the Main Shop, marked by a distinctive cauldron operated by a Witch NPC. Players must act quickly, as the Witch Fuse will be removed in the next update and replaced by an unknown machine, making these fusion opportunities truly limited.
Using the Witch Fuse follows a straightforward process similar to other fusion machines in Steal a Brainrot, but with some unique Halloween twists. Here's the complete step-by-step guide to mastering the Witch Fuse system:
Before approaching the Witch Fuse, you need to select four brainrots from your collection. The beauty of the Witch Fuse is that it accepts any brainrots you own, regardless of their rarity or type. However, using higher rarity brainrots, especially those with existing mutations or traits, increases your chances of getting better fusion outcomes.
Pro Tip: Experiment with common brainrots first to understand the system before committing your rarest specimens. This approach helps you learn fusion patterns without wasting valuable resources.
Once you've selected your four brainrots, you need to bring them to the center of the map where the Witch Fuse is located. Here's how to do it efficiently:
The Collect Zone is clearly marked around the Witch cauldron, making it easy to identify where to place your brainrots. Make sure to bring them one by one, as the system requires individual placement for each brainrot in the fusion.
After placing all four brainrots, the Witch Fuse interface will display a comprehensive chart showing all possible fusion outcomes. This is where strategy comes into play:
Outcome Percentages: Each potential result shows a percentage chance of occurrence. For example, you might see Jacko Jack Jack at 90% and Los Mobilis at 10%. Higher percentages indicate more likely outcomes, while lower percentages represent rarer, more valuable results.
Mutation Panel: Located on the right side of the interface, this panel shows potential mutations your fused brainrot might receive. Mutations include visual variants like Rainbow, Candy, or Gold versions that significantly increase the brainrot's value and uniqueness.
Traits Panel: Also on the right side, this panel displays possible trait additions such as Sombrero or Taco styles. Traits add cosmetic features that make your brainrot stand out from others.
Fusion Time and Cost: The bottom of the interface shows the required waiting time and cost for the fusion. Different combinations require different time investments and financial commitments, with rarer outcomes typically demanding both more time and money.
Once you've analyzed the possibilities and decided to proceed:
The fusion time increases based on the rarity of your submission and the odds of getting rare outcomes. During this waiting period, you can continue playing other aspects of the game while your fusion processes in the background.

The Witching Hour is a special limited-time event that runs alongside the Witch Fuse, offering players the chance to obtain the ultra-rare La Spooky Grande brainrot. This event occurs every two hours and introduces a competitive element to the Halloween festivities.
Event Schedule: The Witching Hour activates every two hours, with a timer displayed above the Witch NPC near the Main Shop. When the event begins, one of four Halloween-themed secret brainrots spawns on the conveyor belt for players to collect.
Required Brainrots: To craft La Spooky Grande, you need to collect all four of these special Witching Hour brainrots:
Collection Process: During each Witching Hour, only one of these four brainrots becomes available. Players must compete to grab the brainrot from the conveyor belt before other players do. This creates urgency and competition, especially on public servers.
La Spooky Grande represents the pinnacle of the Halloween event, offering incredible value and exclusivity:
Strategy Tips: Due to the limited stock and competitive nature, consider these approaches:
While the Witch Fuse offers countless combination possibilities, certain recipes have proven to yield better results than others. Based on community testing and data collection, here are some of the most effective fusion recipes:
| Ingredients | Possible Outcomes | Success Rate | Crafting Time |
|---|---|---|---|
| Noobini Pizzanini (Common) + Burbaloni Lollilol (Diamond Legendary) + Salamino Penguino (Diamond Legendary) + Brr Brr Patapim (Common) | Mamma Rappin (92%) / Bido de Fuego (8%) | 92% | 30 minutes |
| Bandito Bobrito (Rare) + Trippi Troppi (Rare) + Trippi Troppi (Rare) + Tim Cheese (Common) | Tartaragno (83%) / Pinealotto Fruttarino (17%) | 83% | 15 minutes |
| Tim Cheese (Common) + Tim Cheese (Common) + Pipi Kiwi (Candy Common) + Cacto Hippodamo (Rare) | Tartaragno (68%) / Pinealotto Fruttarino (32%) | 68% | 15 minutes |
Mutation Stacking: Use brainrots that already have mutations or traits to increase the chances of your fused brainrot inheriting these special features. For example:
Rarity Scaling: The rarity of your input brainrots directly affects the quality of possible outcomes:
Cost-Benefit Analysis: Consider the investment versus potential returns:
Mastering the Witch Fuse requires more than just following basic steps. These expert strategies will help you get the most value from your fusion attempts:
Begin your Witch Fuse journey with common brainrots to understand the system mechanics without risking valuable assets. Once you're comfortable with the fusion process and outcome patterns, gradually increase the rarity and value of your input brainrots.
Coordinate your fusion attempts with the Witching Hour schedule. Since both events share the same Halloween theme, there may be hidden bonuses or increased chances for special outcomes during Witching Hour periods.

This data will help you identify patterns and optimize your future fusion strategies.
Remember that the Witch Fuse is a temporary feature. Focus on obtaining the most exclusive brainrots first, particularly:
Even experienced players can make costly errors when using the Witch Fuse. Learn from these common pitfalls:
Don't chase low-percentage outcomes unless you're prepared for multiple attempts. A 9% chance means you might need 10+ tries to succeed, which can become extremely expensive.
Using your most valuable brainrots before understanding the system is a common mistake. Experiment with cheaper combinations first to learn the mechanics.
With only 750,000-780,000 La Spooky Grande available, missing even one Witching Hour can significantly impact your chances of obtaining this exclusive brainrot.
Always review the Mutations and Traits panels before confirming a fusion. Sometimes the cosmetic additions can be more valuable than the base brainrot itself.
Different combinations have different waiting periods. Plan your fusions around your play schedule to avoid having valuable brainrots tied up in lengthy fusion processes.
