Asphalt Block

Asphalt Blocks are unique blocks that dramatically increase the speed of players running along them. Their acceleration stacks with other speed-boosting items such as the Hermes Boots and its derivative accessories. It only affects players running directly on it – the speed of Enemies, NPCs and Critters will remain unaffected. Immediately after jumping or falling off of Asphalt Blocks, the speed will return to normal.

With no other boosts, running on asphalt has a max speed of 58 mph, with about 3 seconds of acceleration. Normal running speed is 17 mph.

Tips

 * This is a useful block type for building Skybridges, especially for the late-night collection of Fallen Stars, and is also good for Arenas, particularly where quick movement may be necessary (Skeletron Prime during its 'spin' attack, Empress of Light, Duke Fishron, or Moon Lord).
 * This block only needs to be placed every other tile to achieve full speed. This means you can cover a particular distance at half the cost with the same effect. (not true in 1.4)
