Tachyonic Residue

Tachyonic Residue is like dirt in the Hyperspeed Dimension. When stepped on it can push you back 5-10 blocks back. It will go down for 15 layers (depth by block). Also when stepped on there is a 3% for that block to disappear and then reappear 1 Terrarian day later. It can only be mined with the Shroomite Claws or the Afterimage Pickaxe. The Shroomite Claws take 9 seconds to mine 1 block and the Afterimage Pickaxe will take 1-4 seconds.
