They are both quite well armed for their level. The GP values given in both the DMG and the Epic level handbook does not jive well with how I believe they should be armed. Bear in mind that these two NPCs are part of a five-person team that are the 'final' encounter in a scenario I'm running. Or trying to run - life seems to have conspired with itself to make it difficult.

Further more, there's a rules note that might be of interest when it comes to Suo Nabaal. She's wearing a gem wrapping that covers several item slots. If it is possible to wear part of the gem wrapping without wearing the entire thing, then the prices given are correct. If it is not possible to do so, then the entire item should have a 10%-20% discount, maybe as high as a 30% discount, as it will be much less useful if that should be the case. Andy Collins of the WotC brought this point about item creation up in the first place concerning a new type of magical item he made, the bracer-ring.
