Rubblemaker

The Rubblemaker allows you to place rubble. There are three variants, small (1x1), medium (2x1), and big (3x2), which are toggled by right-clicking them in the inventory. It is sold by the Goblin Tinkerer once the Wall of Flesh has been defeated.

To use the Rubblemaker you must have one of the following items in your inventory:


 * Dirt, Stone, Wood, Coins, Sand, Sandstone, Ice, Snow, Marble, Granite, Gems, Bone, Cobweb, Glowing Mushroom, Hellstone, Lihzahrd Brick, Enchanted Sword, Grass Seeds, Jungle Seeds, Jungle Spore

Each of the items will be required to create the biomes respective rubble. Similar to the Sandcastle Bucket, placing the chosen rubble will consume one of the corresponding items. Destroying the player placed rubble will give you back the consumed item.

Note: All items created cost 1 of the corresponding resource, regardless of size.

You can find a list of all items and rubble placed on the official Wikipedia page
