Tungsten ore

Tungsten ore is an ore unique to the planet Vulcanus. Due to its extreme hardness, it can only be mined with a big mining drill, and takes five times as long as regular ore to mine. It usually spawns inside demolisher territories, forcing the player to defeat the creature. It can be crafted into tungsten carbide or smelted at a foundry into tungsten plate. It can also be found in volcanic rocks, as well as the rocky remains left behind by a dead demolisher.
