(Champion Concept, AP Melee Assassin) Haraba, the Mirage of Shurima

Haraba, the Mirage of Shurima (Is an AP, Melee Assassin)

Lil back story: Haraba is a malevolent entity who preys on those who venture the shurima deserts, mostly men. Haraba lures her prey by creating a mirage of an oasis and disguising herself as a beautiful young woman, or with multiple illusions of woman before devouring her prey.

Haraba is from a similar tomb which had rose from, she was sealed within a sacred magical urn which was opened by who was exploring the tomb at the time, he emptied the urn pouring out the soul sand contained within it, freeing Haraba.

(I don't know if i should link her more with , maybe his mother ect..? or an ancient threat to all ascended released once more after a thousands of millennia have past.)

^Thoughts?

--Abilities! (Mostly descriptions no stats atm.)

(Passive)-Soul sand Haraba ignores unit collision, has increased attack speed (scales by lv), basic attacks deal bonus magic damage (scales by AP).

(Q)- Sandstorm Haraba unleashes a sand storm traveling in a selected direction dealing magic damage to anyone hit. The sandstorm then persists for a few more seconds after it has finished traveling its full distance. When Haraba is within the Sandstorm she has increased movement speed, the attack speed and bonus magic damage on her basic attacks from her passive are doubled.

(W)- Disperse After a brief delay Haraba becomes invisible for a short duration. If she basic attacks an enemy who is alone while invisible she slows them and also breaks her stealth early. Basic attacks and abilities cancel the stealth.

(E)- Sand Dune Haraba creates temporary terrain which is impassable to all except her, she can go through it. Sand Dunes can be created on existing terrain allowing her to go through it.

(R)- Mirage After a 1 second channel Haraba creates illusions of herself next to all enemy champions and attack them. At any time she wishes Haraba can take the place of one of those illusions. Illusions last for 4/6/8 seconds. When Haraba kills an enemy she can take the place of another existent illusion on the map. Illusions deal 40% of Haraba’s damage and receive 20% less damage.
