Blocks



The environments of Terraria are mostly made up of blocks such as dirt and stone. Most blocks can be collected with a Pickaxe. Different blocks may require a higher grade Pickaxe 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 (note that Glass will shatter when hit, and can't be recollected once placed), and any blocks with a Tree, Chest or a Demon Altar placed on top.

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.

Traps
Traps were introduced in version 1.1 and can be found in caves and tunnel systems throughout the world.
