Stronger than stone, but weaker than iron. This mod adds tools that are crafted the same way as the vanilla tools, using bones instead of wood, cobblestone etc... but it also adds a Bone Broad Sword, a Bone Battle Axe, a Bone Bow and Bone Armour. Recipes are listed below.
Do you think you could make a mod for padded armour? So, you could use wool or leather to make a piece of armour as normal, but then you could combine that with iron,gold or diamond armour. This could maybe increase your speed,jumping distance ect.
The crafting recipie might be:
(Where leather is either leather or the clothes/padding)
Clothes/Padding(leather could be used instead as this.):
Awesome idea. I think combining leather armour with any of the other armours to give a particular enchanted armour will work. Things like, as you said increasing speed, or jump distance and other things like fall damage protection or extra strength.
