User blog comment:ChickenRave/Mackal, the Hat of Insanity/@comment-26188361-20150322020040/@comment-26030737-20150322190818

Actually, I prevented this abuse simply by writing in the ability's details "The cooldown starts when the HatBot explodes.". This way, a HatBot will hunt you down until it explodes (and since they have no HP they won't die), so the more you kite him the more Mackal has to wait until he can cast his spell again. As a counterpart, these robotic hats also go faster and faster the longer they live, making them difficult to avoid for a good amount of time.
