How to Get Battery Buster
Unlock via progression.
Best use cases
- Use Battery Buster when you want a hybrid plan with medium tempo and variable reach.
- Good weapon choice depends on whether the route rewards spacing, burst damage, blocking, or close-range pressure.
- Keep a backup plan for enemies that punish this weapon's recovery or preferred distance.
- Judge it by room control as much as damage: the best weapon for a route is often the one that keeps Mina safe while preserving tempo.
Route notes
- Location/progression note: Unlock via progression.
- Test the weapon in a short enemy loop before spending resources around it.
- Pair weapon choice with Trinkets that cover its main weakness rather than only boosting its strength.
- Revisit the choice after every major upgrade, because a weapon that feels slow early can become cleaner once the supporting build catches up.

- Use the Build Planner to compare how this weapon changes a full loadout instead of judging it from one room.
Common mistakes
- Choosing it only for damage without checking recovery, range, and room shape.
- Using the same punish timing on every boss instead of retesting after each new pattern.
- Ignoring Sidearm and Trinket support when the weapon leaves gaps in safety or reach.
- Keeping the same weapon for every room even when the route has shifted from exploration to boss attempts or cleanup.
