Chlorophyte

Chlorophyte is a green fantasy metal obtained from Chlorophyte Ore.

It is used for tools, armour and alloying.

The ore, as in game will spread to adjacent grass and dirt blocks though very slowly. It is essentially a dirt block with the mineral inside and as such, a shovel instead of a pickaxe is needed to mine the ore.

When a full set of armour is equipped the player will have a "leaf crystal" permanently affixed above them which will fire projectiles at hostile mobs.

With its ability to spread to other dirt and grass blocks, it is cheap and easily farmable.

It only generates in jungle biomes and takes a while to spread.

Known alloys are:
 * Shroomite

Chlorophyte is from Re-Logic's 2D sandbox, survival game Terraria. It is a hard mode ore that will expand to nearby mud and grass in the underground jungle.
