Asphalt Block

Asphalt is crafted at the Blend-O-Matic which is a unique crafting station bought from the Steampunker for at night. Two Stone Block and one Gel is required to craft one Asphalt

The block increases the speed of players running on it dramatically, compounding with other speed-boosting items such as the Hermes Boots and its derivatives. It only affects players running directly on it: mobs' speed will be unaffected, and as soon as a player jumps or falls off, their speed will be quickly reduced to normal.

This makes it a nice material to build sky bridges with, for the late-night collection of Fallen Stars. It's also a good platform for an Arena, for fighting a boss where quick movement may be necessary (e.g. Skeletron or Skeletron Prime during their 'spin' attack).
