[@MelonHead] Good character, though I'd like you to further explain how those weaknesses are actual weaknesses. I can sort of see the second one, but ultimately that one would come down to you deciding which cues he'd miss. 

The first goes over my head, as, I never really see not using X weapon as a weakness when you have another weapon, that can probably be augmented with poison.

Well, I was under the impression Elves are physically frail? So running up and shanking someone puts you close enough to get pummelled. It also removes one of the greatest advantages of guerilla warfare by taking away your ability to fight from range. This is also in conjunction with his addiction to a stimulant, which you may have missed.

Secondly, the lack of social skills puts him at a disadvantage using his poisons, as does his first weakness, because he can't easily talk his way into someone's confidence and then poison them. He would also fail to recognise a number of things that would seem obvious to anyone who had visited a city before such as -

1. Guard posts
2. Marketplaces
3. Slums
4. Criminal areas
5. What symbols mean in regards to different shops

So essentially my characters main weaknesses are a lack of combat skills save for the ability to use a knife (in conjunction with a stimulant which has its own negative effects) an inability to shoot a bow and therefore poison people from range, and a lack of social skills which makes poisoning people covertly difficult.

I can add more if this doesn't seem like enough.
