Help me figure out how to successfully fight. Serious question, loving the game - but I need to figure out what weapons and training I need to fight successfully. Such as, I can't lockpick to get past the first part of Rattay - at all (ps4). Very easy is too hard, and I can't pay for training because I can't open the chest. 

I can't even put a scratch on the executioner with the axe I have when trying to murder him for his keys. 

Help me know how to start solving problems with violence.
