[Rewrite] Jadice, The Whisper Of Limbo

I present the rewritten version of Jadice, since I felt that my previous version had little flavor. The general identity is still there, but I added a couple of different mechanics to her kit. This version is my dream Champion, one that utilizes a Full AP build, and has natural AD/health bonuses based on her passive.

Echoed Agony - Jadice throws spiritual energy in a wide cone, inflicting 50/90/130/170/210 (+75% AP) magic damage on enemies and Slowing them by 50% decaying over 3s. This spell gives up to 3 Black Soul stacks, regardless of units slain in one casting. <Mana> 55/60/65/70/75 <CD> 10

Beacon Of Sorrow - Jadice consumes one Black Soul stack to blast the target enemy with spiritual energy and inflict 35/55/75/95/115 (+20% AP) magic damage and mark them for 3s. If Jadice hits marked units with a basic attack at this time, they take 100% bonus damage and are Stunned for 0.75s. <Mana> 45 <CD> 13

Duskbreak - Jadice becomes Stealthed for 0.5s and dashes a fixed 450D over the duration, receiving 40/45/50/55/60% bonus Attack Speed and 3/5/7/9/11 bonus Attack Damage per Black Soul held for the next 7s. <Mana> 50/60/70/80/90 <CD> 16

Last Rights - Jadice channels for 2s before teleporting to the target enemy Champion within a 1200/1450/1700D area and inflicting 250/325/400 (+45% AP) True Damage. If the target is slain, Jadice heals for the total damage applied. <Mana> 200 <CD> 160/145/130

Ability "Black Souls" - Jadice harvests one soul from any slain unit, receiving 10/18/26/34/42 bonus health per stack, with a maximum of 10 stacks at any time. Upon death, Jadice loses all but 1 stack if more than one was held prior to dying.
