All Greatshields Damage Negation by Affinity
Darker column contains Guardian's Greatshield.
Silver Mirrorshield also included due to exceptional magic negation despite being a medium shield, but only in the magic row. Its negations for everything else sucks. Can be good for Maris and Caligo.
When I started making this I didn't even realize there were greatshields with negations below 50, so Ant Skull and Erdtree are like Alaska and Hawaii now.
I hope somebody finds this useful.
