The Beartrap is a block from Witchery. It is used to capture entities in their place, primarily for use by vampires. It can be set and unset by activating the block. When set, it will be partially transparent to all entities except the one who set it. Walking over a set Beartrap will paralyze the entity for 30 seconds and deal 4 damage.
It is used to create the Wolftrap.
