The Fallen Hero
Master Assassin; Hybrid
This really helped! Thanks!for daggers, I like blade of woe and mehrune's razor or the dragon priest dagger just for fun. for the bow, you can use the bound bow for a while in the beginning (depending on how much you use a bow vs dagger) and you can get the nightingale bow from the thieves guild later on which has a fantastic late-game enchant lvl (above 46).
get and use the aura whisper and throw voice shouts for sneaking and I like marked for death for straightforward battles.
The shadow stone is a fine choice any time but I started trying the serpent stone just for something different (5 sec paralysis and 25 damage). I like it well enough. Of course the thief stone is good for early to mid game.
