Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Mods New Modder is Lost [ ENHANCED EDITION ]

...Where do I even begin getting started modding for EE?

I'm trying to make simple mod for me and my friend to have our own Main Campaign [as in, a modded Default Campaign] experience with various altered stats, skills, shop listings, drop tables, craft recipes...?

Where do I change these things?
How do I get started here? I'm so confused.
