Rating
Steel is an S-tier evolved ball from the Stone line. Where Stone deals maximum damage on the first hit and diminishes per bounce, Steel is the inverse — it starts at double damage and gets stronger with each additional hit, stacking up until it reaches a maximum multiplier cap.
This creates a ramp-up damage curve. Early hits are strong (double damage), and each subsequent hit on the same targets pushes damage higher. Against a boss or high-HP enemy that stays in range for multiple hits, Steel can reach its cap and output enormous single-target DPS.
The movement speed reduction is a meaningful drawback in mobile scenarios, but in bouncy environments with many walls and obstacles, the slower trajectory can actually increase total hit count — which benefits Steel's core stack mechanic.
When to Pick
- Boss encounters where you can keep hitting the same target repeatedly
- Builds that favor single-target focus over spread AOE
- High-bounce environments where slow ball speed means more wall contacts and hits
- When you want the highest possible single-target damage ceiling
Best Characters
| Character | Synergy | Reason |
|---|---|---|
| Boss-specialist builds | S | Repeated hits on one target ramp Steel to max cap quickly |
| Long-duration builds | A | Longer rounds = more stacking time = higher final multipliers |
| Bounce-heavy builds | A | More bounces generate more hits, accelerating stack accumulation |
Recommended Passives
| Passive | Synergy |
|---|---|
| Physical damage up | Increases base damage at all stack levels |
| Stack cap increase | Raises the maximum possible damage multiplier |
| Stack persistence | Reduces or eliminates stack decay between hits |
| Speed reduction mitigation | Offsets the movement speed penalty |
| Bounce enhancement | More bounces = more hits = faster stack buildup |
Tips
- Focus one target — stacks reset or decay when you switch targets; commit to single-target focus to maximize cap buildup
- Boss fights are ideal — boss HP pools are large enough that stacking time doesn't go to waste
- Use slow speed strategically — a slower, heavier ball can bounce more before leaving the arena, racking up extra hits
- Don't waste the 2× first hit — make sure the first contact lands; the guaranteed double damage is a free bonus on every new target
TL;DR
Steel reverses Stone's diminishing-return mechanic into a ramping-up stack system that starts at double damage and scales higher per hit. S-tier single-target damage scaling. Best in boss fights and high-bounce builds.
