Brew of Bats

The Brew of Bats is a throwable potion from the Witchery mod. This potion, when thrown at a surface, will cause several bats to spawn around that area, and give everything in that area the Slowness effect for a few seconds. You can create three of these potions by throwing the following items into a Kettle: a Concentrated Bat Ball, a Sugar, a Wool of Bat, a Fermented Spider Eye, a Gunpowder, and an Apple.
