Noob question about the scion build path

So I've tried this a couple times to pick the scion class. But all the guides have you start at a different spot on the passive tree. How do I change my lvl 1 point 1 starting point in the passive tree for scion?

Once you ascend the Scion, depending on what path do you go, you can start from a different character start point. The rest is resolved by Orb of Regrets.
