🧪 How Battery Works
Battery is a straightforward tempo booster: increasing Attack Speed by 8% helps more hits land in the same window, which benefits sustained-fire weapons and “on-hit” effects. Attack Speed doesn’t alter raw damage per hit; it raises your damage throughput by letting your weapons act more frequently.
Attack Speed scales especially well once your area coverage and projectile count are adequate—then speeding up delivery yields visible gains.
🔓 How to Unlock Battery
Requirement
Raise Cooldown Tome to Level 5. Once reached, Battery enters your item pool for future runs.
- Prioritize Cooldown Tome early until Lv. 5; delay non-essential tome upgrades.
- Open chests consistently to expand your item pool during the run.
- Reset slow starts if progress stalls; fast maps help cycle unlocks faster.

Frequent projectiles benefit from tighter firing intervals.

Stuns/chain hits feel stronger with faster procs.
