Increasing strength, magical aura stats?

[The Cimmerian]

I was wondering do these stats increase periodically as you use melee and magic or is there another way to increase them? Also when you increase magical aura are your spells enhanced and does your strength increase your melee or is it purely cosmetic enhances to your look?

I know the road to rule is how you increase melee, ranged and magic attack power but i wonder if these stats add to it

They change depending on how much you use something like strength goes up faster if you use strength mainly. It is cosmetic but it affects combat too. With a higher magical aura your spells charge up faster and with strength your attacks are stronger and flourish are faster charged and with stature your ranged attacks are stronger and you charge a powerfull shot faster.
