This enemy has high health, long range, decent damage and attack rate, and a 100% chance to freeze Cat Units.
Strategy[]
Although they have very high range and the Freeze ability, their uptime is less than 50% meaning that units with less than 500 range still have a chance against them. Rushers are effective as well because Gentleman Bros’ attack power is not that great either. If you do own any units with above 500 range, they will be very useful against it.
