So, I am not a veteran of this game. I enjoy it, but while I have owned it since 2012, I have only just really gotten into it this past month. My current character is a Breaton with 85 Alteration skill and I have Ebonyflesh and all three Mage Armor perks. With a flat armor rating (AR) of 300, I figured that Mage Armor was pretty nice. However, after looking at the raw numbers, that is only somewhere around a 30% damage reduction to physical damage. Also, that there is a cap of 85% reduction which is achieved somewhere in the 500's depending on various factors. As a mage, I cannot get the mage Armor perk advantages while wearing armor, and without armor I don't know any other way to increase my damage reduction (DR) beyond the 30% or so that I have right now, let alone anywhere near that 85% I read about.
I haven't messed with enchanting much, so is it possible in time to greatly improve my DR or AR by enchanting things like basic gloves and boots? Right now it feels like throwing 3 perk points into mage armor was a mistake.
The school of alteration lets me get 30% magicka resistance and eventually that 30% absorption once I get to 100 skill, and the flesh spells are nice was to augment armor early on. I figured that because i was already heavily invested in alteration I might as well dip into mage armor, but now it looks like I shouldn't have and just stayed with light armor and continued playing more of a nightblade.
I like using magic as a support. Light spells instead of using torches, alteration to improve my armor, illusion to help sneak, and restoration to heal. However I still play more of a melee style. I use destruction as my secondary combat skill instead of archery for ranged combat.
