Fusion Machine Mechanics

The Fuse Machine allows you to combine multiple Brain Rots to create more powerful versions and recycle low-value items. Higher quality inputs (Gods/Secrets) guarantee better outputs.

How Fusion Works

  • Trait Inheriting: If you use items with mutations like Rainbow, Lava, or Galaxy, the resulting item has a high chance of inheriting those powerful multipliers.
  • Fusion Time: Fusing usually takes 1 hour. You can use Robux to skip the timer for instant power spikes.
  • Disco Trait: A Disco Trait effectively doubles the item's cash output. A standard $10k/sec God item becomes a $20k/sec item if it has the Disco tag.
  • Elite Combos: The ultimate goal is to find or fuse a Disco-Galaxy or Disco-Rainbow God for maximum efficiency.

Top-Tier Fusion Results

The update has shifted the meta for a "Pro Base." Aim for these values:

  • Rainbow God (Fused): Up to $50,000/sec (The current peak)
  • Galaxy God (Fused): Approximately $45,000/sec
  • Lava Disco EOC: Approximately $25,000/sec
  • Disco God (Standard): Approximately $20,000/sec

Risk Assessment

  • Risk 1-2 (Safe): High predictability - using 5x God inputs
  • Risk 5-7 (Volatile): Mixing Mythics with Gods - high chance of diluting the result
  • Risk 8-10 (Dangerous): Fusing your highest-earning item with low-tier items - potential progress reset!

⚠️ Warning: The Fuse Machine interface shows percentages for potential outcomes. If the preview shows a lower-value item despite inserting high-tier Gods, try adjusting the combination of items used.
