Void Bramble is a mutated plant that has two very unique properties. Firstly it nullifies circle magic that is started within 32 blocks of the bramble. Secondly, anything walking into the bramble will be teleported randomly to a location within 500 blocks. Once placed, the bramble may only be broken by the player who placed it, or a player in creative mode. The Void Bramble is a way to protect an area from players who want to cause mischief with circle magic.
There is an option in the Witchery config file to disable the recipe for Void Bramble, so server admins can prevent it being crafted by players.
A void bramble is crafted using a Nether Star, Drop of Luck, Mutandis Extremis and Ender Bramble. |
