The environments of Terraria are mostly made up of blocks such as dirt and stone.
Most blocks can be collected with a Pickaxe. Rare blocks may require higher-grade Tools to mine.
The only blocks that can't be mined with a Pickaxe are Wood, which requires an Axe; Spikes and Glass, which require a Hammer; and any blocks with a Tree, Chest or Demon Altar on top, which need to be harvested using an Axe for the tree, or Hammer for the Chest and Demon Altar first.
- ↑ Tool: the lowest tier of a tool capable for mining that type of block.
- ↑ Demonite Ore can be mined with any type of pickaxe when found above ground level. Below ground level it must be mined with a Gold Pickaxe or better.
- ↑ Hellstone will be invulnerable to explosives until the Wall of Flesh has been defeated. After that, any explosive will destroy it.
[edit] Bricks
Bricks are a sub-type of placeable blocks that can be used to build a house or to craft background walls. Pink, blue and green bricks cannot be crafted and are mined from the Dungeon instead. Bricks can be recovered with a pickaxe once placed.
