BALL x PIT All Balls Guide

Ball x Pit takes its roguelike insanity to another level once you start evolving your balls. Each combination can completely change how your build behaves, adding new status effects, damage types, or utility traits. If you’ve been wondering which balls fuse into what, this guide breaks down every known combination and effect in one place.

How Ball Evolution Works

Every ball type in Ball x Pit can combine with another to form a unique evolution. These evolutions grant new properties like bleed stacking, poison spreading, or area explosions. Once fused, that new ball becomes part of your arsenal for the rest of your run.

You’ll find combinations for Bleed, Poison, Burn, Freeze, Iron, Laser, Brood Mother, Dark, Earthquake, Egg Sac, Ghost, and Wind below, plus special and passive evolutions that don’t fit the usual pattern.

Final Blurb

Ball x Pit’s evolution system is what keeps every run feeling different. Mixing elements like burn and freeze or bleed and poison changes how your entire loadout behaves. Try experimenting with pairs that match your playstyle, and don’t be afraid to reroll if your combo isn’t clicking. Sometimes the weirdest fusions end up being the strongest.

FAQ

How many total ball evolutions exist in Ball x Pit

There are over forty unique fusions currently discovered, with more being added in updates.

What’s the rarest ball evolution

Nuclear Bomb and Black Hole are among the rarest since they require multi-step or advanced fusions.

Can you undo or separate an evolution

No, once balls are fused they stay combined for that run, so plan carefully before confirming an evolution.
