You roll dice for all actions and attempts at something. 1 is critical failure while 20 is perfect success. The people notice your race and how you look, if you are bloody from a battle they will be scared and call the guards. "Hit dice" = Damage. Some people will not like your race or your looks and bully/attack you. ((I won't RP for you or your character or ever ask "what do you do?"))
