I have started 4 games and played to around level 5. I finally think i have found the right party for me. My lead character is always a rogue/mage hybrid but I have given up on this character type. I tried several other types but kept coming back to a dex based character. Long story short I settled on a pure rogue with 1h and Bow (for special arrow use). I don't think charisma and bartering are needed so I didn't invest in those. I went with this:
Rogue
1. Pet Pal
2. Back Stabber
(Guerrilla, Bully, Swift Footed, Headstrong.. )
8 dex
6 speed
6 perception
1 Bow
1 1 handed
1 Scoundrel
1 Sneak
1 Bodybuilding (will get willpower later)
Relying on gear for lockpicking, lore master, telekinesis. Might have to save scum a bit early on to get the lore master ability on an item. The two mages will focus on maxing 4 elements while also filling out their spellbooks with 1 point picks in their non focused schools. Fourth character is a 2 handed build.
