Chlorophyte Ore

Chlorophyte is a common ore found in the Underground Jungle during Hardmode, spawning in small amounts and spreading once hardmode has started. A pickaxe or drill with at least 200% pickaxe power is required to mine it. (Drax/Pickaxe Axe and above.)

Tips
Using the full screen map can help find chlorophyte ore really quickly. By mousing over certain areas in the Full Screen Map it will say Chlorophyte Ore when you mouse over some.

Trivia

 * The name Chlorophyte is most likely a reference to chloroplast, Chlorophyta or chlorophyll, which is probably why the tooltip says "Reacts to the light", because chloroplasts, chlorophyta, and chlorophyll in a real life plant cell create energy from light.
