Okay thanks for the response.. well I have no intention to save before sigil stone because that's cheating in my opinion and I don't like to do that. Also I don't have an interest for the gamebreaking enchantments on armor
I wouldn't call them game-breaking. I too, used to enchant three transcendent sigil stones on my clothes: Fire Shield 25%, Frost Shield 25% and Shock Shield 25%, giving me an effective 75% shield in street clothes. (Nowadays I just use one 25% shield, usually fire, for an AC of 25 only.) But even with all these shields, as you level up, you will find that you can still get owned pretty bad, especially against spellcasters. The point though, is to have fun.
