Chlorophyte Ore

Chlorophyte is a Hardmode ore found in the Underground Jungle. A pickaxe or drill with at least 200% pickaxe power is required to mine it (Drax or Pickaxe Axe and above). When Hardmode starts, Mud and Jungle Grass located in the Underground Jungle will begin to convert into Chlorophyte Ore. Once seeded, it will spread to adjacent Mud and Jungle Grass blocks, but will not spread if there are more than 24 Chlorophyte blocks within 38 tiles, or if there are more than 95 within 110 tiles.

Chlorophyte Ore will only seed naturally in the Underground Jungle, but it can spread in any area of the cavern layer and below if placed adjacent to Mud Blocks by a player, regardless of the biome. Chlorophyte will only spread in Hardmode worlds.



Tips

 * Try to leave one block of ore left from every deposit you mine and you can come back later to find it has replenished itself with the surrounding mud.
 * For Chlorophyte farming, spread 6x4 blocks of mud with a kernel of ore in each center, 38 blocks apart, in a row. This will ensure that most mud block has the potential to be a chlorophyte ore given enough time. 6x4 blocks of mud spaced 19 blocks apart (again with a seed ore in the middle of each) still give a >90% conversion rate. (Warning: There seems to be some large scale cap to chlorophyte growth as well, previously it was 150 ore within 80 tile square stopped its growth. Now it seems to be changed as well - 6 chlorophyte cells (6X4 tile size) placed in three columns and 2 rows (with 38 tiles of space vartically and horizontally between them) cannot change all of the mud into chlorophyte stopping at about 70-80%. Precize nubmers are unknown at this time.)
 * Another way of searching for chlorophyte ore is to buy the Clentaminator from the Steampunker and buying the dark blue solution from the truffle. After doing this go to the jungle and spray around with the Clentaminator. This will create a mushroom biome in the jungle, making it much easier to see due to the glowing grass.
 * The full screen map shows Chlorophyte Ore and thus can help finding it quickly.

Trivia

 * The name Chlorophyte is most likely a reference to chloroplast, Chlorophyta or chlorophyll, which explains why the tooltip says "Reacts to the light." In real life, chloroplasts are the sugar-producing organelles of photosynthetic plants, Chlorophyta are a taxonomic division of algae, and chlorophyll is a green pigment used in photosynthesis.
