I am a Breton but even if I got the Mundane Ring, I wouldn't use it. Back when I first played I got the god character with 100% Resist Magic and 101% Reflect Damage and it was no fun after a while and its much funner to RP. I do use the Ring of Vitality though. The alternative would be to become a vampire(I just hate getting paralyzed by Spider Daedra) and I couldn't deal with the restrictions of being one. I have the Amulet of Axes and only use it since I have yet to get a better one in loot with either Health Fatigue or Magicka enhancement.
Yeah, I agree with you Rainman. It's just not very fun with full immunity. My character could have 100% Resist Magic, 101% Reflect Damage, and 100% resistance to Disease/Paralysis/Poison, making her close to invulnerable, but it just wasn't that fun to play. I choose not to use the full Reflect Damage, and built a mod that makes armor enchantments weaken as the armor takes damage - meaning eventually I'm no longer invulnerable to magic.
