I'm trying to maximize the amount of TPs I have available for lockpicking and other types of picking. I'm currently OHE/0.5x TWC/2x Hide/2x Ambush, but I'm sure there's a cheaper, more effective way to go. I'm dancing around a level (30) where most things start working half decently.

Does anyone know which is the path with the fewest TPs that will also be able to keep me alive?
