Corrupters can be bought from the elite shop near teh center of the map. Corrupters are passable at killing enemy air units, and quite good against enemy elite air units like battlecruisers or motherships, but their true strencth lies in their corruption ability. This ability increases damage taken by enemies by 25%, and slows them by 25%, in a splash radius. Corruption can be used to debuff enemy armies or help kill tanky heroes.
