Chlorophyte Ore
Chlorophyte Ore is a Hardmode ore. When Hardmode starts, a portion of Mud Blocks located near Jungle grass blocks (naturally in the Underground Jungle) will be converted into Chlorophyte Ore. It requires at least a Pickaxe Axe or Drax to be mined, whose materials require defeating all three mechanical bosses.
Chlorophyte Ore is renewable; it will slowly spread itself by converting adjacent Mud and Jungle grass blocks into more Chlorophyte Ore. It will also attempt to spread by converting nearby Dirt Blocks to Mud, as well as blocks of Corrupt, Crimson, Hallowed, and regular grass to Jungle grass. Chlorophyte Ore can only spread and convert blocks if it is in or below the bottom half of the Underground layer (in a regular worldVerify). It can only spread itself to directly adjacent tiles (and only if there is not too much Chlorophyte nearby already) and can only convert tiles up to six tiles away.

Notes
- Chlorophyte Bricks also have the ability to spread Chlorophyte Ore.
- Chlorophyte will only spread in a Hardmode world.
- Chlorophyte Ore can spread to hammered, actuated, and painted blocks. This will cause the ore to be hammered, actuated, or painted too.
- Despite being mud-based, Chlorophyte Ore cannot convert Mushroom grass blocks.
- Despite its tooltip and achievement, it does not need light to grow. However, it visually glows green when exposed to light.
- Chlorophyte Ore and Chlorophyte Bricks restrict the spread of evil biomes around them.[1] See Biome spread for further information.

Technical details
For the natural spawning of a new deposit of Chlorophyte Ore, every block of Jungle grass in the lower half of the Underground layer or below[b] periodically has a chance to convert a random Mud Block into Chlorophyte Ore, given the following criteria:[2]
- The random Mud Block is within an 11×11-tile rectangular area centered on the Jungle grass block. In other words, a Mud Block can only turn into a new deposit of Chlorophyte Ore if there is at least one block of Jungle grass within 5 tiles (horizontally and vertically) of it.
- There is no tree, Plantera's Bulb, or Life Fruit directly above the random Mud Block.
- There is not too much Chlorophyte nearby the random Mud Block.
When a new block of Chlorophyte Ore is to be created naturally, either for a new deposit from a Jungle grass block or for spreading an existing vein, the amount of Chlorophyte Ore nearby is checked. The new block will not be created if too much Chlorophyte is already present in the vicinity, to ensure that it does not completely overtake the Underground Jungle. This process consists of two checks. In each check, the game scans a rectangular area centered on the reference tile[c] for existing Chlorophyte Ore blocks. If the number of Chlorophyte Ore in this rectangle does not exceed a certain limit, then the check is considered "passed". Both checks must pass in order for the new Chlorophyte Ore to be created.[3] The limit and rectangle size are lower in the Cavern layer and in the Underworld, causing Chlorophyte Ore to potentially spawn and spread faster there.
| Cavern layer and below | Above the Cavern layer | |||
|---|---|---|---|---|
| Ore limit (tile) |
Area size (tiles) |
Ore limit (tile) |
Area size (tiles) | |
| Check 1 | 40 | 71×71 | 20 | 105×105 |
| Check 2 | 130 | 171×171 | 65 | 255×255 |
| Ore limit (tile) |
Area size (tiles) | |
|---|---|---|
| Check 1 | 45 | 63×63 |
| Check 2 | 1950Verify | 155×155 |
For example, consider a block of Chlorophyte Ore placed in the Cavern layer. It can only spread to nearby Mud Blocks and Jungle grass blocks if both checks pass:
- There are at most 40 other blocks of Chlorophyte Ore within 35 tiles (horizontally and vertically).
- There are at most 130 other blocks of Chlorophyte Ore within 85 tiles (horizontally and vertically).
If both of these are true, then the Chlorophyte Ore is allowed to spread.
Achievements

Tips
- A Spelunker Potion can be used to find Chlorophyte faster.
- When harvesting Chlorophyte, it is advisable to leave small clusters of the ore unmined. With time, they will result in a renewable supply of Chlorophyte.
- Since Chlorophyte Bricks can also spread the ore, the player can craft their Chlorophyte Ore into Bricks to cover much more area for farming.
- A fast way to obtain Chlorophyte in the endgame is via Shimmering Luminite.
Trivia
- The name Chlorophyte is derived from chlorophyll, the color pigment responsible for photosynthesis, plus the common rock suffix -ite.
- Chlorophyte Ore is completely renewable due to the fact that Dirt Blocks can be crafted into Mud Blocks. Dirt Bombs provide a renewable supply of Dirt Blocks, and Stone Blocks and Wood blocks can be Shimmered into dirt.
- Chlorophyta is a division of green algae, informally called chlorophytes.
- Its appearance when placed seems to resemble some plant cells.Verify
