With this pack, tnt placed and ignited on top of a diamond block turns into an op drill that bores clear down to bedrock, making a nice natural-looking cave in the process!

NOTE: regular TNT still functions as normal! It only does this if ignited on top of a diamond block.

Because the explosions are so powerful, you may or may not survive if you get too close in survival. I suggest using a bow enchanted with flame.
