that means if you use an armor to enhance another armor, the 1st number if if the 2 armors have a matching element, the 2nd is if they do not. Like Snakeskin is Earth/Water, used to upgrade Crius Armor(Earth/Air), you get 24 points towards it, because at least 1 element matches. But if you use Snakeskin to level Living Flame Armor (Fire/Spirit), it will only be worth 20 points, because no elements match.
