In Battlecry, every battle reduces your health, and you need to recover it to continue fighting.
Health automatically regenerates over time, but if you want to get back into action quickly, you can use the Repair feature. This allows you to instantly restore your health by spending cash from your Treasury.
Since Repair uses Treasury cash, it’s important to keep some funds stored there for emergencies. Using Repair wisely helps you stay active and continue battling without long delays.
