Evelynn Rework Idea [Top Of Head Post]

Suprise! Evelynn should be a better burst assassin/jungler with this new skill lineup...hope you like it, and as always no haterino, just comments.

[Q] "Spiteful Desire" - Evelynn's basic attacks passively inflict 5/10/15/20/25 (+4.5% AP) bonus magic damage on enemies, which can stack up to 4 times if consecutive strikes are made within 2s of each other. At maximum stacks, this spell can be cast, causing Evelynn to radiate dark energies in a 250D area around herself and inflict 50/85/120/155/190 (+35% AP) magic damage on all enemies in range. <Mana> 80/85/90/95/100 <CD> 5

[W] "Dark Frenzy" - Evelynn gains 15/18/21/24/27% Movement and 50/55/60/65/70% Attack Speed on cast for the next 3s, the duration increasing by 1s per basic attack with a maximum of 4s extension. While empowered, Evelynn has all Slows and Frost effects halved against her. <Mana> 55/65/75/85/95 <CD> 15

[E] "Ravaging Beauty" - Evelynn viciously cuts the target enemy unit, causing them to bleed out for 50/80/110/140/170 (50% AP) magic damage over 5s and reducing their Armor by 10% for the duration. Evelynn's basic attacks on these marked units heal her for 6/10/14/18/22 (+5% AP) flat health per hit. <Mana> 50/55/60/65/70 <CD> 11

[R] - "Agony's Embrace" - Evelynn causes dark energies to rise from the target 425D area after a 0.75s delay, inflicting 200/275/350 (+75% AP) on all enemies struck and Stunning them for 1.25s. Evelynn gains a shield worth 35/50/65 (+20% AP) health per enemy Champion struck that lasts up to 7s afterward. <Mana> 100 <CD> 140/120/100

Ability "Shadow Walk" - Evelynn becomes Stealthed after being out of combat for 7/6/5/4s, recovering 1.5% of her Max Mana every second while this buff is active. Evelynn can still be seen by Towers, True Sight wards and enemy Champions within 700D, but this buff only breaks if Evelynn causes or receives damage.
