When an Eskaro becomes corrupt, a light Eskaro becomes dark, or a dark Eskaro becomes light. Typically with the corruption they grow another pair of ribbons, smaller than their original pair. No matter if an Eskaro corrupts from light or dark, they will always act agressive. There are multiple methods to uncorrupting an Eskaro, the most popular methods being to use a cleansing spell or killing it via shattering both head and chest gems to rid the corrupted Eskaro entirely.
