Dark there are a few problems with this new character. 

I don't mind that you creates a rogue alchemist. However amro rarely affiliates itself with their like. 

1) No one is outside amro's reach. The closest to that is this new organization called the Omerta however amro can track them down as well if they ever wished it. No one can hide from amro, if amro decides you are a person of interest.

2) Amro does not seek help or affiliates itself with rogues, aside from Bloodlines. They are usually seen as a hindrance and are discriminated. However you can still have a rogue hitman or a rogue agent. Their kind still exist and they sell their services to bloodlines etc. 

3) Alchemic style is constant. There is really only three ways to cast alchemy. Through sigils, through verbal commands or through gestures. There is no other way to channel and or cast alchemy. 

4) Blood is being used by another Rper who has reserved it. While persuasion is fine but your use of blood kind of clashes. You don't really need blood contact for persuasion alchemy. Also the use of persuasion is also split. You are showing it as a means of implanting suggestions as well as controlling objects. That is a little advanced for a rogue.
