I always felt like the armor system doesn't make much sense in Witcher so I made it more realistic.
Armor resistance depends on the material it's made of and how much body parts it covers.
Light armors/clothes are weaker and heavy armors are a lot better. (Knight armors are kind of op now)
There's only a small difference between common and relic now within the same armor.

Main features:
- adjusted classes for armors (light/medium/heavy)
- modified the base armor and the resistances of most armors.
- most armors have resistance to everything now (monster, bludgeoning, piercing)
- heavy armors like steel armors are a lot tougher now and light ones are weaker
- stamina regeneration is also faster for lighter and slower for heavier armors
- adjusted armor weights and levels (most armor require slightly lower lvl now)
- all armors are included

- If it's not working with NMM install it manually (I haven't tested it yet)
- The mod works with armors acquired after the installation!
- If you want already owned armors to work: You need to un-equip the armor and drop everything. Save and quit the game. Drop the mod in the folder then restart the game. Get your armor and you will notice that the stats have been modified.
