Shadowleaf, there is no leather armor such as you describe that you can wear at this time, much less studded armor. I think you might be able to wear grizzly bear leathers very soon though.
Through careful curing, the magical properties of various animals are partially preserved in their leathers. The strength and value of these properties vary. Your best bet is to look at a selection of leathers, hides and studdeds in your size range to find what suits you best. I would be happy to help you with this.
Sincerely,
Ferrit Pandorn
