Purifier (mothership)

"Man, did ya see the size of that protoss ship? Don't matter how often I see 'em, those guys always come out with something that makes your jaw drop."

- Rory Swann on the Purifier

The purifier is a type of mothership used in purification attacks. It is protected by shield technology impenetrable to terran attacks, but these are maintained by several nexus; destroying them drops its shields.

History


A purifier was used by Executor Selendis to attack the terran colony on Haven during the Second Great War; the protoss detected zerg infestation spores amongst the colonists and moved to liquidate them. Jim Raynor refused to condemn the colonists who had not yet manifested symptoms of infestation. The ship was destroyed by Raynor's Raiders and the colony was saved.

Game Unit
The StarCraft II mothership had the "Planet Cracker" ability during development. The ability is used by the Purifier. It is technically possible to avoid confrontation by playing Haven's Fall instead of Safe Haven (or by bypassing Haven altogether).
