| Well both Imoen and Nalia are primarily mages, so you will never raise their thiefskills.
Yoshimo is a great thief, and so is Jan Jansen. However, Yoshimo has a part to play in the main quest just like Imoen.
You don't need great thief skills, just buy lots of Potion of Perception and Potion of Master Thievery for those pesky times when the skill isn't high enough. |
