I assume you mean the most recent one I mentioned. 

You'll get one, maybe two skill points to assign at the very beginning. Skills will have elemental requirements(obviously you can't fly if you don't have any air). Your raiment is the source of your elemental power, and it's made up of the crystals you have in the beginning. So that's what it has to do with your skills. If you don't have any earth in your raiment, you can't go slinging rocks. 

Your element thing will look something like this: 

Knight
Earth: 13
Water: 12
Weapon: 5

With your elements almost even, you'll be able to learn most of the early skills. But higher up the skill tree there will be skills that can only be learned if you use primarily one element or the other.

To give an example of a skill under this system, I'll use the same one:

Glide:
Elemental requirement: 8 Air. 

Flight:
Prerequisite: Glide
Elemental Requirement: 12 Air. 

And then dual element abilities, the early ones will just require that you have both elements, but later ones will require more and more balance. Top tier will require you to have it split 15/15(This way there's an advantage to forgoing a weapon, as those who spend crystals on weapons won't be able to use top tier abilities.
