Not sure we're talking about the same things, I'm talking about how Strength will be something like 22 + 1.8 and Agility will be 17 + 0.75 or somethingThey are how much you have added to that stat, be it via items, spellls, buffs, or whatever. For instance, with Invoker, if you have 3 Quas orbs, that's +1 for each to Strength. If you have 3 Quas orbs and an Iron Branch, then that's +4 for strength, +1 for agility, and +1 for intelligence.
Edit: Is that the amount by which that particular stat increases whenever a level is gained?
