Thaumic Spikes are a block added by Thaumic Bases. It is an upgrade to Iron Spikes and will inflict 14 () points of damage to mobs that come into contact with it from above. When the Spikes kill a mob they will become bloody and can be wiped off with Enchanted Fabric, which will turn it into Bloody Enchanted Fabric.
These Spikes will not destroy items. They can be rendered harmless with the presence of a Redstone signal.
