No really.
Besides the obvious inside joke ...
3e Rogue that is the party Face.
Diplomancy with fixes.
Shapechanging and disguises.
And FIRE !!
... FIRE !!!!!!!!!!!!!!
You can build something kinda like this in 4e.
Not quite a legit concept / workable PC.
Changeling Rogue/Sorc with lots of specifics.
(I'm not going to critique 4e skill challenges
even if that is the direction of this build)
