Maplestory "High Five" Private Showcase

Seems to be one skill for now.
But if I understand the description in Max's blog correctly, then more "skill cores" will be added to the game later.
They were more focused on designing the system (and the Matrix) than thinking up actual new skills for 40 classes (which, let's face it, is what held 5th job back all this time).

What I'm struggling to understand is the system. Maybe you can help shed some light for me. I saw in one videosome guy had combart orders and demons metamorphis skill. So how exactly does this work? Do you have Combat Orders?

Also: Looking at the world map those next two areas must be coming in this update or at least really soon. I'm sure this is a multipart patch
