Sundering basics:
All items have hardness
Items hardness varies depending on hardness of the materials it is made of.
Looking at armors' hardness’s and ran into a question... What is the hardness of those composite armors... aka armors made of multiple materials.
Easy to figure out:
Leather, Studded leather, Hide: Hardness 2
various Chain armors: Hardness 10
Breastplates & various Plate armors: Hardness 10
Scale mail: Hardness 2, 10, or something in between?
(Scale mail is made of small metal plates riveted to a leather backing)
