low lvl assasin build (help)

Hi, I'm totally new to the game and I was wondering if anybody would be willing to help me? I created an assassin and I'm super duper weak like I can barely move from act 5 without dying multiple times T_T. I really like the game but dying a lot can be stressing and boring. I know I'm doing something very wrong since I just pick out random skills. I'm using a blade furry which almost deals no damage atm and I'm wondering if there's a better build for me to use to kill mobs a lot faster for me to level? :(
Would greatly appreciate your help, thank you very much.

Message me in game and Ill see if i can help you

I will sir, tyvm :D
