Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - General Guide to maximizing EXP gain on a run?

[MINIMAL SPOILERS!]

Greetings, all! Does there yet exist for public consumption a guide that details all relevant steps to maximize EXP gain for a playthrough? I'm curious what level we could reach with such a method. 23? 24? Other?

Thankee!
