Wormite

"A rare ore that spawns in worm-like strands and in small chunks."

Wormite is a special ore in Tangy Mines as it spawns un-naturally compared to the other ores.

Wormite can also be found as a randomly spawned ore. It can be found between -100 and -199.

Currently as of version 1.3.4 (Alpha). It could have been used to craft the Wormite pickaxe.

Wormite sells for $30 at the Sell Ores NPC.
