Dark Corpus

The Dark Corpus is an organ shared by all the spawns of the Death Gale. When one of them is slain, a Dark Corpus containing the essence of the demon soul will be dropped.

Consuming Dark Corpus is currently the only way of actively increasing Corruption. Doing so can be useful to take advantage of the effects of some armor pieces such as the Greaves of the Vanguard or the Veil of the Ascetic.
