I've been playing Final Fantasy 14 for a couple weeks now, and I'm running into something I can't seem to figure out. All my spells have a "Potency" attached to them, ranging anywhere from 20, right up to 100.
Checking a couple wikis, the best I get out of them is, "The mathematical base damage of an ability.", which doesn't really tell you much about how it actually works.
Is potency a percentage-based value? Or how does it work to apply damage to whatever it is I'm targetting?
