This ability repairs all of your vehicles and buildings.
You will choose one of your cities or an area of your vehicles. A mysterious ball of energy promptly falls from the heavens and explodes upon impact with the ground, restoring a moderate amount of health to any of your vehicles or buildings within the blast radius.
If used on one of your cities (after the aura makes contact with the ground), citizens will appear surprised at first, staring into the sky. Shortly afterwards, they shrug, then go about their usual business.
