Durability Condition
Introduce a condition to Crucible that can check the items durability. Mechanics can conditionally check durability before skill mechanics, such as an item ability that requires 10 durability to cast, and cannot be cast with a durability below 10.
Original pitch
Can be used in conjunction with the ModelSet mechanic to change the items custom model damage based on the durability of an item. An example is having 3 AK-47 model data weapons. 1 as a pristine AK47, one is a worn AK47, and one as a broken AK47. As the durability reduces the item can show this by making their items look more worn out.
