Paving Stone of Warding

The Paving Stone of Warding is a block added by Thaumcraft 4. It acts like a Fence; it will prevent mobs, except the player, from walking on the top of the block.
Giving the Paving Stone of Warding a Redstone signal or placing a block above it will disable its functionality.
