Titanium is a material of high quality that makes armor and weapons with high durability and increased damage. Titanium is similar to iron, gold and diamond in that it is found as an ore and smelted into ingots. The ore and ingot are easily identified by their green shade. The ore sells for $41 and the ingot sells for $156 to the Merchant.
The ore is rare and somewhat difficult to find, for it's ore spawners have a very long regeneration period. The ore can only be mined at level ten with a stone pick.
Titanium has no use other than crafting armor and weapons.
