We know that in Minecraft the Obsidian is one of the hardest blocks, so it would be a shame do not use it. But now, with this mod, with get access to a new gallery of items and blocks made by obsidian.
Blocks (both of them can't be destroyed by explosions, so it's a good idea use them for creepers)
-Obsidian Dust (to get it we need to pick the obsdian block with the drill)
-Drill (if it breaks, we can repair it)
-Sword, Axe, Pickaxe, Shovel, Hoe (the same use that diamond, but with durability of 2000)
Armor (like the diamond)
-Head, Chestplate, Leggins and Boots
Mod contain also available in Spanish and French
Any suggestions please share it.
