I would be all about this IF they made it so you could strafe while holding up your shield. It's way too hard to focus on a moving target without locking on, but if you could strafe, I think it would be fair.

Fog ring should work as Theifs Ring worked in Dark Souls, As in it should make you COMPLETELY INVISIBLE at a certain range, but moving into range you gradually become visible.
Basically 15+ feet away= totaly invisible, 10 feet away regular Fog Ring visible, 5 feet or closer Totally visible. The Hidden Body spell should work the same way but make it much more potent, say not totally visible until they are right in your face, seeing as it only has 3 casts and lasts 30 seconds long.
Give me this FROM SOFT and i guarantee there will be a thousand topics on here asking for advice to building a Stealth Build, which me and my associates will happily reply to each and every one!
