Mutandis

Mutandis is an item from the Witchery mod. This item is used to mutate plants into other, random plants. This is the only way to obtain certain Witchery plants, like Spanish Moss, Rowan Saplings, Alder Saplings, and Hawthorn Saplings. Mutandis can be upgraded into Mutandis Extremis, and is also used in transmuting meat items into other meat items. In the Spirit World, Mutandis can be used on other plants to create Nether Warts.

As of Witchery 0.21.0, custom plants added by other mods can be added to the mutation list through the config file.

Usage
Simply use the item on any non-staged plant block, such as the vanilla Flowers, Tall Grass, or Saplings. A multi-staged plant is a plant that grows steadily, like Cacti, and Wheat. The plant you obtain by doing this is random, and can be a vanilla plant, so it is recommended to get lots of Mutandis if you plan on performing magics that require many different forms of plants.
