The character I have planned out would use mostly defensive magic, with staves and runes for damage. No weapons. Will use Wards. Probably use a follower. I don't *plan* to get hit a ton, if that makes a difference.
IIRC the DR cap is reached at something like 567 displayed armor rating. So a 300 AR with Ebonyflesh and 3/3 Mage Armor (which takes fairly deep investment) is more than half that. I guess add on 50 AR from the Lord stone. Then if I'm using wards, that could be another 40-60 points. So say a high point of 400 AR.
I'm just wondering about the long-range usefulness of those 3 perks, when Dragonhide will eventually make them irrelevant. Is Dragonhide *so much* better than working up the Mage Armor perks that they're not very beneficial?
Edit: Hey Pseron, festive avatar! I've got a real glass cannon mage running right now - Destruction only, 100 Health. So I want to make sure my next mage can take a few hits!
