I really missed the Equipment Durability System plugin after moving to 1.6+. So I eventually sat down and tackled the process of migrating the system over to CommonLib-NG. All features of the original mod are completely intact. So here is the description from the original mod:

Weapons and armor that actors are equipped will be degraded when attacking or getting hit. Supported armor slots are 30: head, 31: hair, 32: body, 33: hands, 37: feet and 39: shield. Weapons and armor (in NPC's inventory, in containers, dropped) are randomly tempered. Adds widgets that display weapons, armor and shouts that the player is currently equipped.

No ESP file.
