When you are attacked and you lose the defense battle, your Base will take initial damage and then additional damage over time (burning damage). Once the burning time is over, the Base will automatically start repairing. The auto-repair process will restore the Base's health over time. You have the option to restore the Base's health instantly using Medals. When your Base takes burning damage, you have the option to extinguish the fire using Medals. If your base's health drops to 0, you will be automatically teleported to a random location on the World Map.
