BigNorseWolf directed me to a post that says you can use a race boon when rebuilding, but the post is about Pathfinder Society. I know a lot of stuff carried over from Pathfinder and a lot of logical stuff simply carried over, but a lot of it seems to be just be understood but not stated in text.
Most race boons state: "this Chronicle sheet must be the first Chronicle sheet for the given character". Can that line be overridden when rebuilding?
Is the post correct for Starfinder, as well? I don't doubt that it does, but it would give me peace of mind.
Thanks for that.
I kept reading past that post and found that this post seems to answer my question a little more clearly.
