Red Matter Hammer

When forged, the Red Matter Hammer can destroy stone and ore faster than a diamond pick axe and will never break. When you charge it with V, the hammer can go up to four different levels. By right clicking it when it's charged, the hammer destroys all rock within a certain area, leaving only dirt, sand, gravel, clay, water, and lava. All destroyed blocks drop on top of you for easy pick up.

Secondly it has two left-click functions, toggled with "G":

Normal impact mode: digs one block at a time Mega impact mode*: digs a 3x3 area


 * This mode will take the time of whatever block you are hitting, regardless of the surrounding blocks
