The Hi-Metal class of armors, especially the lower grade, is one not often seen among hunters due to various reasons. Though the armor itself isn't terribly expensive in regards to its defense and such, making the armor requires 13 pieces of Machalite Ore, and most hunters early on would prefer to spend the precious few Machalite they obtain on the improvement of their weapons instead. That's not to say that the Hi-Metal armors are not worth the effort to make, though, as the low-grade Hi-Metal is the earliest of the "Get Heavy" class of armor - the big, bulky armor that's focused more on standing in the midst of battle and taking hits than using a hit and run strategy. This is encouraged by the inherent Health +20 Skill already in the armor (Though the Gunnery Skill isn't always useful).
