I figured since the game just came out, this will be patched fast, and I will share this great exploit.
Firstly, bind an ability to your hot-bar of your choosing. Just make sure it effects your charector and is self targeting, no enemies required.
For instance, the Early Sorceror Spell: "Force Bubble". So, spam this key as often as you like. It will increase your skill of the ability being used, like "Self Alteration" for Force Bubble.
I find it best to use on the long trips in between cities.
