Fast+9 runs in Ball x Pit demand early momentum, reliable crowd control, and late-game scalability. Surviving the opening minutes is often the deciding factor; once your build stabilizes, most strong evolutions can carry you to the finish. This guide breaks down which Evolutions consistently perform in Fast+9, how they scale, and what infusion pairings generate the most impact.
The evaluations below focus on two key criteria:
- Early-game reliability
- Strength against heavily packed enemy waves in mid and late game
Tier List
S Tier – Exceptional and Consistently Dominant
These Evolutions solve early survival and remain lethal throughout the run.
Holy Laser, Sun
Holy Laser delivers reliable lane-clearing power from the moment it’s online, and continues to scale well with fusion synergies. Sun stands out as the best early-pick among its fusion line because it deals immediate damage and stabilizes crowded starts better than Flash or Flicker.
A Tier – Strong Picks With High Synergy Value
High-impact evolutions that excel when paired correctly and rarely disappoint.
All Beam Evolutions, Maggot, Bomb/Nuclear Bomb, Frozen Flame, Overgrowth, Flash
Beams provide broad utility and exceptional synergy with status and hit-based triggers. Maggot is a top-tier trigger engine, Bomb and Nuclear Bomb scale explosively, and Frozen Flame plus Overgrowth significantly improve mob control. Flash is a solid alternative when Sun isn’t available.
B Tier – Situational but Can Shine With Support
Useful in the right setup, but usually require fusion or other Evolutions to feel impactful.
Hemorrhage, Flicker, Shotgun
Hemorrhage excels in boss encounters but can feel unreliable for wave clear without the right pairing. Flicker is strong when fused but risky to start with. Shotgun offers decent burst but lacks consistency compared to Beam or Laser options.
C Tier – Non-essential and Often Outclassed
Nice bonuses, but rarely the reason you win a Fast+9 run.
Leech, Sacrifice, Spider Queen, Mosquito King, Voluptuous Egg Sac, Magma, Inferno, Phantom, Swamp, Glacier, Sandstorm, Mosquito Swarm, Blizzard, Lightning Rod, Storm
These can provide utility or niche advantages, but most can be replaced by higher-tier choices with better returns.
D Tier – Poor Value for Fast+9
Generally not worth investing in during Fast+9 attempts.
Vampire Lord, Virus, Berserk, Succubus, Incubus, Lovestruck, Assassin, Black Hole, Noxious, Wrath, Soul Sucker, Satan, Nosferatu
Low impact, slow to scale, or easily replaced by better options.
Recommended End-Game Combinations for Fast+9
These fusion paths consistently produce high-performance results in late-game waves:
Maggot x Holy Laser or Nuclear Bomb
A reliable trigger engine paired with devastating screen-wide damage.
Flicker/Flash/Sun x Overgrowth/Hemorrhage/Frozen Flame
Combines strong triggering with powerful DOT or mob-shredding effects.
Ghost/Noxious/Sandstorm x Holy Laser
Mitigates wave pressure while allowing Laser effects to sweep the field.
Nuclear Bomb x Dark
Explosive, high-impact control with massive late-game payoff.
Infusion System
Each ball functions primarily as either a Trigger or a Damage Source. Strong infusions pair a Trigger-type ball with a DMG-type ball, enabling damage effects to activate as frequently as possible.
Below is a breakdown of commonly used bases:
Trigger Types
T1 – Universal Triggers (All sources)
Maggot, Mosquito Swarm, Mosquito King, Voluptuous Egg Sac, Spider Queen
Reliable and frequent activation across many builds.
T2 – Status-Only Triggers
Blizzard, Storm, Inferno, Noxious, Sandstorm
Trigger status effects but lack broad damage coverage.
T3 – Full-Screen Trigger-Style
Sun, Flash, Flicker
Flicker and Nuclear Bomb are the only true full-screen triggers, but Sun and Flash are grouped here due to similar practical influence. Note: Nuclear Bomb can trigger Black Hole across the entire screen, while Flicker cannot.
Damage Types
D1 – Hit-Triggered Damage
Holy Laser, All Beams, Bomb, Nuclear Bomb, Lightning Rod
Ideal when paired with high-frequency triggers.
D2 – Launch-Triggered Damage
Swamp, Magma, Glacier
Activates on projectile launch rather than hit.
D3 – Damage-Over-Time
Overgrowth, Frozen Flame, Hemorrhage, Phantom, Inferno, Virus, Leech
Excellent with full-screen or frequent triggers; ramps up into heavy crowd control.
Lasers can technically act as T2-style status triggers due to their ability to apply DOT on hit, but they perform best as core damage engines and are treated as D1 for optimal pairing.
Infusion Pairing
Overpowered Synergies
T1 x D1 and T3 x D3
These pairings activate high-damage effects constantly across the battlefield, creating reliable wave control.
Solid Combinations
T1 x D2
Decent utility but lacks the explosive potential of the above.
Conditional Option
Noxious or Sandstorm paired with Holy Laser or Beams can work, but Ghost or Wind-type infusions generate similar results with fewer drawbacks.
Weak Pairings
T2/T3 combined with D1
These lack alignment in activation pattern and often feel inefficient.
