Lock and Key (Bibliocraft) (Bibliocraft)Edit
The Lock and Key is currently an item only available in Creative Mode.
It can be used to lock Bibliocraft blocks into place and make them indestructible from mob or player griefing in Survival Mode. Only the player who locks the block will be able to unlock it, even if another player also has a Lock and Key.
Right-clicking with the Lock and Key on a block will lock it into place, and right-clicking on the block again will unlock it.
