New Champ Idea

I have a new champion idea :D She´s called Dibe ´´The Evil Ninja`` She is AD. Can be playd Mid, Top or Jungle. She is Assassin. Passive: Lifesteal Q: Dash forward. can dash through walls (gives her 10 mr and 10 armor for 10 seconds) W: becomes invisible for 2 seconds and she comes visible she gets +10% of her dmg E: Active: Gives her attack speed. Passive: 4/8/12/17/22 more dmg. R: Slows all enemys and steals 30/50/100 dmg (GLOBAL) Lore: Dibe had old sensei. Sensei found Dibe when she was a couple moths old. Sensei was demanding something from Dibe all the time and then Dibe got pissed and killed her sensei, when she killed him her katanas turned red and her hair turned red too, then she got scared and ran away. Dibe traveled everywhere occured until she got an idea to train even more and go to public fights. Every fight she attended she won but then she lost to a girl and got pissed again then dibe began to destroy places. Then man with wind tactics found her and they started to train together and Dibe wasnt pissed anymore and then the man asked her to come to a place where you can fight as much as you want...
