Blood Water

Blood Water is a thrown consumable weapon that deals 20 damage on impact, while also transforming a small number of blocks at the impact site into Crimson, which can then spread to other blocks. Blood Water affects blocks within a 9-tile diameter of the impact point, corrupting up to 57 blocks total. (Untested, assumed from Unholy Water)

It requires Crimsand to be crafted, which can be obtained from crimson areas that overlap Deserts, though other crimson areas may have converted Sand Blocks to Crimsand during world generation.

It is the Crimson counterpart to Holy Water and Unholy Water, used to respectively create small areas of Hallow and Corruption.

It has a much smaller and more precise range than Red Solution.
