I saw that someone had already copied over a subclass I'm trying to make but I can't follow it without a subscription so I was wondering how they made tables for stats and things and where I put them?

If your playing with a DM that has a subscription ask them to share a link to their content.  

I am not certain but you may still need at least a basic subscription to see the content. 

I share all my content with the people in my group. 

Hello there getshrektm847,

If you head over to the “Homebrew & House Rules” forum, there is a pinned ”How-to” post. It should have instructions there to help you.
