Blocks are the primary components of every Terraria world. They make up nearly all of the game's terrain, with the preponderance of a particular block type in an area determining its biome. Nearly all blocks are collectible for use by players, and are mined with a Pickaxe or Drill. All block types can be stacked up to 999 in a single inventory slot.
- The most common blocks are Dirt and Stone.
- Blocks can be crafted into walls and vice-versa. Nearly all block types have a corresponding wall type.
- Blocks can be shaped into half-blocks and angled slopes using a Hammer.
There are currently 192 block types, including both natural and player-crafted types.
Naturally Occurring Blocks[edit | edit source]
These blocks are created when the world is spawned. Though few of them are renewable, more can always be found by generating new worlds.
Soils[edit | edit source]
Soils are the most accessible type of block in the game, and they make up the majority of the world. Many of them grow Plants naturally. All soils can be mined with a Copper Pickaxe or Tin Pickaxe (except for the Stone variants as noted below). Soils are the only blocks that can be converted by the Corruption, Crimson, and Hallow. All soils are destroyed by explosives.
plants Blocks[edit | edit source]
These blocks drop when their respective plant is looted from the environment using the necessary tool. Once in the player's inventory, they can be placed like other blocks and likewise looted with a Pickaxe, Drill, or explosives.
Other Found Blocks[edit | edit source]
These blocks are found in different parts of the world.
Ores are found underground (With the exception of Luminite), some types only in certain biomes. They are used in the crafting of Bars, which in turn are used to craft Weapons, Armor, Furniture, and more. Many are used to make Bricks or other blocks.
Gems[edit | edit source]
Gems are valuable materials that can be found in veins underground. They can be found in two forms; as gem blocks embedded in Stone Blocks or on the sides of Stone Blocks, or as background objects placed onto Stone Blocks. Mining either version will provide the respective gem type. Gem blocks cannot be created by the player as placing a mined gem will always create the background version.
Bricks are a specific type of crafted block with a repeating rectangular pattern. Though many bricks are crafted from ores and soils, some can only be looted from the environment (or in one case, enemies). All Bricks have the word 'Brick' in their name (however, Mudstone Brick is called Mudstone Block on Template:Console iconTemplate:Mobile icon).
Bricks have no sell value. All crafted bricks are made using a Furnace.
These blocks are solely obtained through crafting at a crafting station.
Other Blocks[edit | edit source]
These blocks are bought from NPCs.
Looted Blocks[edit | edit source]
These blocks are obtained in various ways, mostly as drops from enemies.
