It all looks good to me, and Phantom, the Alchemist is not going around 'clinking', he's more the sort that goes around carrying a bomb or two to toss onto someone that tries to cause a problem.
He's got a bit of skill with diplomatic things, but I figure that a thief would know him better through work. He buys and sells merchandise that might not be exactly legally acquired afterall.
He's not able to do it at 1st level, but later on he's also a source for some healing potions, if he has to brew actual potions for that, it costs more but those last as normal potions ought to, as for him making some alchemist brews, he should later be able to one into a cup and tell a person to drink it up there. Letting its magic heal those that come to see him, but not letting anyone walk out with a vial of his alchemist brew though. So, later on he ought to be able to help heal some things at least.
As for other things, he's a bit social character, but don't know who he's connected to and who he is not. He has possibly sold the "Alchemist's Kindness" to most folks that drink too much, that is, hangover cure. As for other things, he has a number of things that might help a thief at some point, but that might also work for more common folks.
Anyway, going to see how it turns out. I figure that my character might not have any pre-existing links to others, or he might have afew, going to wait and see how it goes.
