Ball x Pit Tips and Tricks
Each entry below is one mechanic, what it costs you, and the update it was last checked against. Filter by category or difficulty to narrow the list, and use the anchor beside any heading to link straight to a single tip.
Bosses
#Erosion shaves current health through every Serpent layer
Built from Time plus Wind, it takes 3 percent of current health per hit and pierces infinitely through the mechanical snake's layered protection, which is the fastest answer to that fight. The Makeshift Sisyphus and high-tier Poison melt it the same way.

Builds
#Maggot's baby balls cover the Nuclear Bomb cooldown
The bomb detonates for 300 to 500 damage and stacks radiation that raises damage taken, then goes quiet for 3 seconds. Every kill it makes triggers Maggot to spawn baby balls, and that flood is what blocks enemies through the gap rather than any defensive stat.

Characters
#The Makeshift Sisyphus cannot damage anything on impact
That is the whole character, not a drawback to build around. In exchange every AoE and status effect gets a 4x multiplier, so high-tier Poison or a Nuclear Bomb carries the entire run and a collision damage ball contributes literally nothing.

#The Embedded pairs with the one bounce-punishing relic
It pierces infinitely until a wall stops the ball, so the Argent Stopwatch and its 150 percent damage on pierce costs you nothing. That relic normally sheds 30 percent per bounce, which is a real tax on any other character and no tax at all on this one.

#The Empty Nester cannot spawn baby balls at all
Brood Mother and Maggot builds are dead on that character, which quietly rules out most of the strongest wave-clear packages in the game. What it gets instead is the ability to fire multiple special balls at the same time, so build around volume rather than spawns.

Special Balls
#Black Hole destroys itself after every single kill
It then sits on a 7-second cooldown, which makes it a wave-clear tool rather than a source of damage. Build it as the thing that buys you space and keep a real damage ball beside it, because a run leaning on Black Hole for DPS stalls out the moment a boss appears.

Ball Builds
#Evolve your pairs first, then fuse the evolved balls
A fused ball only mixes two movesets that already exist, while an evolved one gets a brand new moveset that is usually stronger than either ingredient. Stacking two evolved movesets into a single ball is how you reach the damage numbers an NG+ run asks for.

Base Layout
#The gold corridor traps workers where the mines are
It is the community-optimized base topology, a narrow lane lined with Gold Mines so nearly every bounce lands on a gold source. Documented builds run 7 mines for 2,500 to 3,100 Gold per harvest, or a 12-mine version reaching 3,000 to 3,500.

Passives
#Cornucopia turns baby balls into a defensive wall
It evolves from War Horn plus Baby Rattle and massively raises baby ball output, which is what makes the screen between Nuclear Bomb detonations almost impenetrable. Take it whenever it appears, because the passive is doing defensive work no ball can replace.

New Ballbylon
#A failed run still pays you a free harvest
You get one per completed run whether you won or lost, and the Spa sells additional harvests for escalating gold on top. That makes a short dead run worth finishing rather than restarting, and it makes skipping the base phase the only genuinely wasted move.

Resource Selling
#Selling resources crashes the rate for about 13 runs
Focus the layout on Stone and Wood, bank 10,000 or more of each, then bulk sell into Gold at the top of the rate, where 10,000 Stone is worth roughly 400,000 Gold and 10,000 Wood roughly 100,000. Stone recovers at about 3 Gold per run, so the cycle needs patience.

Achievements
#35 of the 63 achievements are hidden with no hints
Only 28 are visible from the start, and the game tells you nothing about the rest. Most of the hidden set is tied to clearing a biome with a specific character or creating a specific evolution, so a character you never touch is a block of achievements you will never see.

Ball Upgrades
#Fission, Fusion, and Evolution are three different things
Fission randomly upgrades the levels of your current balls or passives, and pays gold instead once everything sits at Level 3. Fusion merges two unfused Level 3 balls into one and frees an inventory slot. Evolution combines two specific Level 3 balls into something otherwise unobtainable.
Verified on Shadow Update
#Fusing below Level 3 destroys both components
Balls have to reach Level 3 before they can evolve, and you level one by collecting duplicates. Run two Level 1 or Level 2 balls together and you get a weaker plain combination rather than the evolution, with nothing to show for the pieces you spent.

Characters
#Characters unlock from housing, not from milestones
You find a housing blueprint during a run and build the matching structure in New Ballbylon, which is how 20 of the 21 unlock. The False Messiah is the exception, being a PC-exclusive Twitch unlock, so no amount of building will produce that one.
Verified on Shadow Update
Evolutions
#Nosferatu wants three pre-evolved balls at once
A Level 3 Vampire Lord, a Level 3 Mosquito King, and a Level 3 Spider Queen, each with its own multi-step recipe underneath it. That means planning the whole run around it from the first floor, and expecting several Fusion Reactor drops plus tight inventory management.
