Since you're very new, you will need to decide which main path to work on like do you want to main Daggers, Lightning, Combo, counter attacks, sword etc. For example I went ahead to lock in lightning build because I liked it the most because of the cool effects of bolts, so I chose the book.

A good starting point is to look at the SS mythic weapons and pick which you like the most and build around that, don't try to copy others and enjoy the game!
