Huh, interesting, so they did change the stat pairing up. And changed the amount too; Kinshi's +40% as opposed to Nandi's +30%.
Actually, now that I look at things again, they've done similarly with the +attack/+15% defense pairing. Iwanagahime and Python are at +30% element, while Stolas and dark Iwanagahime are at +40% character.
