Because iron and even diamonds are easily obtainable early-game in optimized play, this data pack aims to reward players for exploring and looting structures to find iron and diamond armors, while still giving an option of chain armor (marginally better than gold armor, but easier to obtain and more stylish.) Additionally, includes horse armors, because why not!
