🔓 How to Unlock Speed Boi
Requirement: 🗿 Complete any stage with 2 or more Boss Curses active.
Each activation duplicates bosses/minibosses, making fights harder while improving rewards. See our overview of the mechanic in this Boss Curse explainer.
Route your build for sustained healing (regen or lifesteal) before activating the second curse. Clearing under pressure is the whole point—survive long enough for Speed Boi to shine.
🧪 How Speed Boi Works (verified)
- Trigger: Only when you’re hit while below 50% max HP.
- Effect: Temporarily slows time and grants a 2× damage buff.
- Notes: Exact duration/cooldown are not officially stated; treat it as a clutch window rather than a permanent state.
All statements above are corroborated by multiple independent guides and community documentation.
🔗 Recommended Synergies & Play Patterns
These picks help you capitalize on Speed Boi’s “danger → payoff” loop:
Gamer Goggles
Pairs well with “low-life” windows; take fights on your terms and burst when time slows.
Mirror
Reflects damage when hit—great during clutch trades where Speed Boi already slows time.
Thunder Mitts
Extra on-hit pressure during your burst window; stun chains are easier in slow time.
Lightning Staff Builds
Controlled stuns and safe clears while you dip under 50% HP to trigger Speed Boi.
Don’t over-invest in fragile, glass-cannon picks when you plan to hover under 50% HP. Reliable sustain beats marginal DPS.
