So as above it's probably overpowered and should as such never be introduced seriously into the game, but for *** and giggles I'm suggesting it.

3 new types of jewellery, instead of + hp +stamina or + magicka, have items in jewlery slots that simply read "counts as x armor type" Think spiked knuckles for heavy armor rings, scarves for light armor necklaces and such. Like i said It'd probably be OP given that one could gain rediculous bonuses such as 9% weapon crit from the medium items, even if it does mean sacrificing 200+ health as a result.
