Titanium is a very rare and valuable metal found within the lower earth level rock; Gabbro.
Considering it's incredible durability, remarkable friction and naturally extensive carvability, it has been used mainly as a combat material.
Titanium arrows are the best arrows Malhalla has to offer 3 times more effective than even ruby arrows, and only two shots from them are enough to kill almost any living thing on Malhalla, sole exceptions being Trolls which typically take up to 5 at most.
