Well knight is the best class to start with and if you two hand your weapon you can get some extra ar you are going to be rolling mostly anyways and if you don't want to be invaded when embered play offline and then if you get to a boss you need help with switch it off don't forget you actually have to reload the game for it to take effect and remember there is nothing wrong with running past an enemy also make sure you open shortcuts before a boss fight it will save you a ton of time and if you need any more help I am more than willing to answer your questions
