If I am right, what you read were CR1 attribute statistics.
Now, Belief increases melee accuracy, viral damage, and boosts for melee resistance and viral defense along with several other state increases. All of them are percentages.
Perception deals with ballistic damage and defense, as well as thrown accuracy and thrown resistance and state increase that escape me at the moment.
Reason is Thrown Damage and thrown defense, along with viral accuracy and viral resistance, again with state increases I do not remember.
Focus increases melee damage and melee defense, as well as ballistic accuracy and ballistic resistance. I believe it increases stun duration and another state.
Vitality, to my knowledge, is broken and only increases your initiative bonus.
For a martial artist, I would say your best bets are focus and belief - starting off with belief for the accuracy and viral defense since a lot of npcs are hackers and the resistance bonus you would get from focus wont really help much at your current level.
