You're most welcome.

 

You might miss some new abilites which were introduced with WMI & II and are accessible from lvl 7 on - even in the main game. But you can always take them ona later levelup of course, when you installed the expansions. The expansion maps should be entered from lvl 8 on I'd say. So... if you don't play beyond lvl 7 you're save. 

 

Perfect, thanks! I don't think I'll make it to 7 before the weekend, so that should work out well.

google for pillars of eternity steam guide 2.0 - its not super new but i think its mostly still quite accurate - i think the same  guy has also a youtube channel with guides - alternatively look for Pillars of Eternity: White March 2.0 from nerd commando game studios - these are pretty good guides imo.
