My apologies, but this thread is off-topic for our site. When you signed up for Roll20 you agreed to abide by our Code of Conduct and this post violates the Intended Use section of the code. Since this is a question about roleplaying game mechanics, you’d be better served posting it on reddit.com/r/rpg , or the wizards.com site. Most GMs will be more than happy to help you create your character once you've joined their game. In fact, they'd likely want to be involved in it anyway. I'd suggest using the Looking For Group tool, or Looking For Group forum to find a game first and then discuss with the GM about how to make your character.
