Ruila, the Mind's Bane

Lore: Years ago, Ruila's brother was a lover to a legendary warrior. The warrior was swift and precise with her best weapon,spears. Ruila's brother was weak, not a fighter. He tried his best to do his best but had few capabilities. So he trained. But Ruila trained as well, in dark arts. She quickly began to excel in preying on feeble minds and bending them to her will. Her brother was aware of her power, the only person who was, and, fearing of her using it for wrongdoing, made her swear an oath. AN oath to never use it for devious plots or selfish desires.

 During a great war, the legendary warrior was called upon to help and prevent a massive catastrophe. Little did she know that Ruila's brother would be there. There to kill her. As the warrior bled to death, it is said that there was a flicker of anger in her eyes. Her last words were spoken then, and haunt many who heard. When she passed, Ruila's brother suddenly had a change in emotion, completely different from what feelings present during the murder. He began to cry, which took many by surprise.

 Ruila appeared at that moment, a devious grin on her face.  Her brother looked into her eyes, knowing that Ruila was responsible.He was sought after by authorities, who never found him. Ruila goes on to this day, feeding on the minds of the weak and forcing them to do her bidding.

"You're minds are strong. In my hands." -Ruila.

Abilities:

Passive: Insanity: Being around Ruila causes enemies to lose there sanity, applying a stack of Chaos each few seconds they are in a medium radius. Each stack reduces their armor and magic resist by 1 and increases the duration of Ruila's fears slightly. Caps at 10 stacks.

Q: Wit's End: Inflicts massive emotion into an enemy, fearing them for a short duration.

W: Dark Paradox: Targets an area, then causes all enemies in the area to struggle on a twisted paradox, marking them causing them to gradually lose a percentage of their max health over a few seconds. If they become feared during the duration, they will take bonus damage.

E: Intrusive Thoughts: Fires a projectile towards you cursor, dealing hard damage to the first target hit. That enemy will gain extra Chaos stacks for the duration.

R: Feeble Minds: Targets a feeble mind and preys on it. All of their abilities become Resist, which applies a stack of Resistance (Activating on key activates it for all). If they damage you, they gain a stack of Resistance. If they attack another unit, they gain a stack of Resistance. If they do not have 5 stacks of Resistance after 4 seconds, you gain control of their mind for a long duration. You can freely move them around and attack enemies with them or cast abilities. However, you become inactive and immobile, very vulnerable.

Can only be cast on feeble minds, so you can only cast on feared targets, targets with 10 stacks of Chaos, or marked by Dark Paradox.

I have another concept that I'll let out if people like this one. May or may not be Ruila's brother.
