Blood Rain Bow

The Blood Rain Bow is a pre-Hardmode bow which rains 1-3 streams of blood from the sky, rather than arrows. Each shot consumes one arrow from the player’s inventory. The streams fall in a widespread area where the cursor is pointed, but are blocked by solid blocks. The tooltip might be a reference to the album "Reign in Blood" by the thrash metal band "Slayer"

Its best modifier is Unreal.
