Can anyone think of a way to get armor points? If I know the damage before and after the armor reduced it, that would already suffice. Don't use reflection Link Don't hardcode the armorpoints Link
Reflection will break with every update Hardcoding armor doesn't allow for custom armor from mods which I want to support and not have to hardcode for every new piece of armor
You could do a personal study on the effects of each piece of armor and use that knowledge to manually change the damage values. This would take a while, but it would work.
