How do Divinity Runes calculate percentages?
I have 181 magic armor. I equip a Medium Masterwork Rune that says "Maximum magic armor +20%". How is it that I only get 5 more magic armor? Seems I used a lot of valuable resources to make things to upgrade to medium and then I realized it does't do much at all.
Runes only increase the armour of the piece of equipment they're slotted in, not your total armour.
