I didn't go with total immunity, but a knight in full armor is highly resistant to all forms of magical attack, which was my explanation for why armor would continue to develop into heavier forms when a fucking wizard could just fireball a cavalry wedge. It's a bit like the bullet proofing old armors used to go through - genuinely could stop a ball shot from a certain distance. Not necessarily at point blank and definitely not a fucking cannon ball though.
Ironically I autism'd this not because of any desire for verisimilitude but because the idea of wizards just incinerating hundreds of screaming horses upset me so I wanted a way for barding to legitimately lend them protection
On the flip side, 'natural' organic or semi-organic materials hold and conduct magic extremely well. This includes wood, bone, amber, and crystal. Mages will often have bits of armor or at least bracers made of bone so as to lend them some sort of protection without inhibiting magical ability.<span class="post-quote">

No, but the natural iron content in humans bodies does limit their capacity for magic. Anemics are ironically better mages. This is were the stereotype for physical weakness<span class="post-quote"> <a class="post-backlink" href="#71013582">>>71013582</a></span>
Elves actually have blue blood because theirs contains copper, not iron. Dwarves meanwhile have a comparative surplus of iron in their blood. Dwarven organs act as an extremely efficient filtration system, so they absorb and hold iron better and do not suffer as much from hemochromatosis like humans would. As a result dwarven blood is a deeper, darker red.</section>
