Bomb Farm Extra Battery Ability
Extra Battery is a self-scoped Bomb Farm ability that reduces the Energy spent by its carrier while that hero is working in the field.
Extra Battery improves the field time of one hero by lowering that hero's Energy consumption. It does not reduce Energy use for the rest of the active team, so its value depends on whether one important unit is ending the rotation earlier than everyone else.
How this entity works
When Extra Battery helps
Use Extra Battery when one damage dealer, Collector, or utility hero leaves the field before the rest of the squad. Extending that specific hero can stabilize a farming composition without spending a team slot on broader recovery support.
What it does not solve
The effect belongs only to the carrier. If the entire squad drains Energy too quickly, compare it with Miner's Stamina or improve clear speed first. A self-only sustain skill cannot repair a rotation where every active hero empties at the same time.
How to evaluate it
Record which hero reaches the House first during a repeatable stage. Extra Battery is useful when that hero is the real uptime bottleneck. If another unit still forces the team swap, the ability may be better on that unit or replaced by a team-wide effect.
