Brew of Crimson Shade

The Brew of Crimson Shade is a potion added by Botania. It gives the Bloodthirst effect to the player who drinks the brew.

In effect, it allows hostile monsters to spawn within a 64 block radius of the entity, regardless of light level or other spawning conditions. This includes allowing Slimes to spawn outside of Slime Chunks. The Managlass Vial variant of the brew carries 4 doses, and 6 for the Alfglass Flask variant. The effects of the brew lasts 6 minutes for the potions. When brewed as an Incense Stick, the effect lasts 6 hours when it is burned on an Incense Plate.
