A tiny visual tweak that would visually reinforce what “Elemental resistances” means, would be…
On the resistances part of the Character card… It says “RESISTANCES” and then it lists the 7 schools of resistances. Below the left-three schools (fire, lightning, cold) that make up “Elemental” Resistances… write the word “ELEMENTAL” and draw a little horizontal line to group them with the word…
Obviously not necessary, as the tooltip says “adds to your fire, cold, and lightning” resistance, but it would be a nice touch that would make this just a little more visually reinforced, in the place where the resistances are displayed.
If you want to get really fancy, the subtle “ELEMENTAL” title could say something like “ELEMENTAL (14%)” showing how much of your elemental resistance is coming from elemental bonus, vs specific type bonuses.
I would post a picture, but well, we cant.
