Unholy Water

Unholy Water is a consumable weapon that transforms a small area into The Corruption when thrown. It can be used as a weapon, but deals relatively little damage compared to other Hardmode weapons. Unholy Water is the Corruption counterpart to Holy Water.

The weapon is Hardmode-only in the console release because it requires Ebonsand to craft, which can only be obtained with the Corruption spreading into deserts in Hardmode. However, in the PC release, Ebonsand can be created during world generation should the Corruption overlap any sand, thus making this item available pre-Hardmode.
