A fun thing people often forget about Mage Armor is that you can cast it on other people, which is occasionally even helpful!
Wizard: I shall also wear armour.Fantasy lore: no, you can't wear that. Wizard: why? I'm going to be fighting too. I don't want to get stabbed by the first guy I see and die.Fantasy lore: no, it wouldn't be fair on the giant dragon or the deamons I'm sending you to fight. Enjoy your robe.
