Item "Skills" and Stones

Ah thank you for the info on “Nature” sounds like the best way to change overall stats to a named item.

Perhaps “Item Skills” is just generic in the item info screen.
See in the screen below, the Pendant has “Fester ## Elementalist” which gives “+#% Element Effect duration”.
That “Fester” in the “Item Skills” is what I want to change on the Pendant to "Reclaim # " which gives “+#% to cast Skullshield on attack”
Can that be changed by a stone?
