Character Creation

In a nutshell, to pick whatever class you want to start as, always choose the Virtue that corresponds with what class you want to be, each time that option to choose it is presented.

Tinker Paladin RangerShepherd
Example ~ You want to be a Tinker.. then you would choose 'Sacrifice' everytime you see it, which would be:
Answer 3 - Answer 6 - Answer 7
Result - Tinker

Basically, just take that, and switch it out for whatever virtue it is for the class you're wanting to play as.
