Ascendant question

How does it work? Do you have to do lab 3x in order to get two real class nodes? What happens to the last 2 points from uber?

I think it is

1st point stats
2nd point passive
3rd point class node
4th point 2nd stats
5th point 2nd passive
6th point 2nd class node
7th ? 8th ?

With the last 2 points you can start at the root of on class. Usually when you do a scion, it is to go in two side from the tree that are far away from each other, so it is pretty usefull. For example for a build that I am trying to make, I choose to start at the beggining of the marauder class (poeurl.com/bd6t)
