Purifier beam

Purifier beams are a type of protoss ship weapon, consisting of a destructive discharge of crystal energy. Motherships are equipped with purifier beams, which constitutes the craft's primary means of defense. In combat, it rapid-fires six controlled bursts which, while not very powerful on their own, can track and strike both air and ground targets effectively.

Carriers have been observed to utilize a similar weapon for use in the glassing of planets, projected from their bows.
