d8, 6 skills, medium BaB, weapons and armor like a rogue.
Class abilities mostly deal with using and mastering shadows. They also get a few talents similar to rogues and a choice of fighting styles. With Daggers, bolas and shuriken they add a bonus to hit/dmg as they level (up to a +4), also deadly focus add wis mod to hit/dmg(if the assassin kills them they can reuse the power after a 15 min break, otherwise they can not use it till the next day), they can learn to by pass DR. Those are a few example abilities they get.
Closing thoughts, If you want a assassin with a mystic/supernatural bent with shadow powers then this is a very interesting class. All and all i liked the class but felt it makes a more interesting challenging NPC class than PC class. If it was possible i would have given this a 3.5, but felt it was not good enough for a 4 star rating, so I rounded down to a 3 star.
