I started off spreading stat points out relatively evenly, for the first 3 or 4 levels. The next 3 or 4 I tried to concentrate more on Strength and to a lesser extent on Dexterity, but it varied based on bonuses on equipment that I upgraded to, or requirements on new stuff. Around level 8 to 10 I had more melee and ranged resistance than magic, and started to run into more mages, so boosted Intelligence some more. Playing again I'd probably only put a few points into Intelligence, and see if I could get by with being more vulnerable to magical damage (temporary boost potions are an option for tough fights, or equipment enchantments could help with resistances).
Thanks for the guidance. I think I'll put a few points in Dex/Int over my next level or two (just hit level 5 and put points into both of them so I could equip a bow -- using a bow makes certain encounters much easier right now).
I also stuck a point in Lockpicking and have opened a few chests with it. I found a skill book so I have 3 unused skill points right now, which will probably remain unused until I hit level 6 for some skills and then again at level 10. I'm not sure how many skills I can expect to max. I guess I'll end up with roughly 35 skill points by the end of the game? So I could max about 6 skills (with single points here and there in other skills, like Healing, Rush Attack, etc.)
I appreciate all the tips. I like having some general knowledge regarding point distribution in games like this, because I don't want to back myself into a corner later.
