1 - Okay. but its a machine. It didnt bring you the knowledge of who killed James brother and where.
2 - Alright. James knows how to use his Electrical Arc.... But Light and Electric are two diffrent things. Even if James watched his brother all day everyday his entire life he wouldnt be able to master it so fast. Watching and Doing are two diffrent things. James saw how it looks. But James doesnt know the right Mind set for each diffrent ability the Light Arc has.
Magic is the most powerful element in the game, but the User becomes addicted to it. After a while, the user will become magic crazed and overpower the device, thus being sucked into the Arc, making it more powerful. ((Will explain the Arcs fully, if anyone is interested.))
Magic has to be used in check, and not thrown into overdrive very often.
Just to be fair, I am going to go ahead and warn you that at some point you have to fight a shadow of yourself. It will be just the exact same as you, except for one tiny detail (of your choice). You can fight them at any time of your choosing, and if someone attempts to assist you, the shadow will disappear and come back another time. I would advise fighting it semi-early, so not as to beat them to quickly, and so you aren't too powerful to beat yourself. Oh, and you can fight your shadow multiple times if you want to.
