So unfortunately, this kind of patch really won't work for me. It's disappointing, of course, but I'll just have to accept it and play with only 24 talents...

It's a shame, but I suppose there aren't any other mods (or patches) that only unlock parallel skill trees specifically tied to professions - only those that grant access to all trees across different professions. I did plan to play a long modded campaign, but I never intended to devote my entire life to completing it with every single skill tree unlocked. For me, 48 talents (I calculated the total number of talents for a single profession – where you can originally only research one of two available options – excluding, of course, the Assistant who has an additional skill tree branch) to research across core professions would've been quite the ordeal!!!

You have to put it above Baroverhaul Classic

I place this mod under "Baroverhaul - Classic", but I can still only use the talents of one column. Did I do something wrong?

This lets you unlock every talent for the job you pick. All + Parallel Unlock lets you unlock every talent for every job, regardless of which job you pick.

what is the difference between this and Baroverhaul - Classic All + Parallel Unlock?
