Barbarians, as the other NMU guild, have a wide variety of magic items (roar helms, face paint, voice beer, fear cloaks, shark teeth) which are fairly potent within their tradition.
Is there any intention or design for thieves to have access to something along these lines? Concentration boosting/restoration items, stealth boosters (hello thug powders?!), things like that.
Personally I'd love to see more of an alchemy style bent where we can use consumable items which are easily bought/made from regular stores inside the guild and stored inside 'dirt pouch' style containers.
If not, I think it would be nifty if we could 'active' magic devices like runestones in some fashion; we lack the obvious anti-magic bias of a barbarian, and our abilities are intrinsically 'internal focus' oriented, it could arguably be, er, argued, that thieves could screw up their mental focus and courage enough to get an effect out of a magic device. Obviously not charge one, but limited use/manipulation would give us a pretty cool niche.
Obviously there'd be no spell casting actively, but with runestones, and similar activated devices, you channel the magic from the device rather than specifically from yourself. It doesn't really square with magic theory in DR as a whole, but it could be explained fairly easily depending on the exact definition of 'inner magic' in 3.1; if we take the anime approach and say thieves are now ninjas (since so many love to play one) and then further take some stereoptypical ninja anime, thieves totally manipulate essence or chakra or something. Totes makes sense. Though we have to wear black to use magic devices now.
