What it does
Blocks are grouped by difficulty, from a Normal block and a Hard block up to an Extreme demon block, plus blocks named after other demons and a 555 block described as the hardest of the set to break. Two tools, a sword that deals heavy damage and a pickaxe that breaks stone quickly, are added alongside them.
