Brew of Frost

The Brew of Frost is a throwable potion from the Witchery mod. This potion, when thrown, will spawn a 3x3 sheet of vertical ice on the block that the potion lands on, and is directly affected by orientation. What this means is that if the player is facing diagonal to the block that the potion is thrown on, then the ice will also be diagonal. You can create three Brews of Frost by throwing the following items into a Kettle: a Glistering Melon, a Snowball, a Red Mushroom, an Icy Needle, a Water Artichoke Globe, and an Odour of Purity.
