The Blood Rain Bow attacking Target Dummies.

The Blood Rain Bow is a pre-Hardmode bow which rains 1–3 streams of blood from the sky instead of 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. It has a 12.5*1/8 (12.5%) chance to drop from a Wandering Eye Fish or Zombie Merman.

Its best modifier is Unreal.

Tips

While using this bow, unique arrow effects are not applied. It is advised to use arrows with high damage, which carries over to the blood streams. Also, it has a low base damage of 14 and a very fast effective use time of 9.5 (2 shots on average per use), making the arrow damage more significant.
- An especially powerful choice is the Shimmer Arrow, which has no additional crafting cost over the Wooden Arrow and can be obtained prior to any bosses (provided that the player has explored The Aether biome), and has a base damage of 12, falling only behind the Hellfire Arrow by 1 base damage in pre-Hardmode. Since unique arrow effects are not applied, the Shimmer Arrow's drawback of being hard to aim due to reversed gravity is completely negated.
The Blood Rain Bow can be useful for fighting the Eater of Worlds due to the large hitbox of its long body, which mitigates the projectiles' inaccuracy.

Trivia

The bow can be considered a pre-Hardmode counterpart to the Daedalus Stormbow due to its similar ability to rain projectiles from the sky.
If Blood and Gore is disabled in the Settings, the bow rains down greyish clouds instead. Its functionality is unaffected.
The tooltip 'Reign in Blood' is a reference to the thrash metal band Slayer's third studio album by the same name.
