[Champion Concept] I dont have a name for the Champion

So I thought about a concept for a champion, I made her a female but it can also be a guy (just saing cause I write "she" in the descriptions) I have not thought about Lore and Design, but "she" should have a sword with like 4 different modes. Though I thought about the abilities:

Passive: Cooldown 14s-6s Every time "She" used an ability, her next auto attack deals more physical damage (Lvl. 1-18 - 15-45)

Q: Cooldown 9s Mana 15/20/25/30/35 Range 600 "She" dashes torwards an enemy (skillshot), hits with her sword (45/65/85/95/105 +0.70AD) and jumps off behind the enemy champion, then "she" gains a movementspeed boost over 2 seconds (1%/2%/4%/6%/8%)

W: Cooldown 18/16s/14s/12s/10s Mana 50/60/70/80/90 Range 250 Creates for a short period of time (3s/5s/7s/9s/11s) or until she uses an ability a field. On that field her next ability needs no mana (if she hits), the cooldown halved and she gets a little movementspeedbuff of 30 that subsides over 1 second.

E: Cooldown 20s/18s/16s/14s/12s/ Mana 60 She gains for the next 2/3/4/5/6 seconds bonus AD (10/15/20/25/30 +0.90AP)

R: Cooldown 110s/100s/90s Mana 100 Range 550 Enemy is stunned in the air for 1,5s/2s/2,5s and she jumps through him and deals 200/250/300 true damage

This is the first time I've done this, so forgive me if my scalings are a bit crazy. If you have any suggestions for the design, the lore or changes then write them in the comments and maybe we can do something great :D
