Navigate to https://pathbuilder2e.com/ and create a new character on STARBUILDER 2E
Do not add anything else, but the current selection should look like this:
You will be met with A LOT of information, what’s most important is that you understand that this is a very interactive sheet, so you can create your character while following the rules of the system, and without having to know anything.
It will give you all the resources to learn about the different ancestries, backgrounds, classes, and how you would like to build your character.
I suggest that you build your character up until LEVEL 3! And don’t build further, unless you’re purely interested.
