First time trying this, do'nt know much about ap or ad ratios but I got most of the other stuff done.

Gwendolyn the Toxic Step backround

As a young girl, Gwendolyn grew in Zaun and wished to be in the spotlight. Being an ambitious girl she learned to dance at an early age, and by her early 20s she was a renowned dancer. However, after rejecting a suitor's advances she suffered a "mysterious" accident that left her feeet horribly burned by a corrosive acid. Filled with despair she nearly gave up on her dreams, until a promiment Zaunite scientist saw potential in her. He outfitted her with biomechanical feet taht would function as her own, with the added bonus of spreading the very same acid that burned her. Now, hoping to get back into the spotlight she has turned to the Institute of War.

"Her step is as light as a feather and as toxic as a cobra"-Zaunite Scientist

Attributes- Melee, Assasin, Support

Innate: Tip Toe-Gains increased movement and attack speed per nearby ally

Q: Entice-Taunts an enemy into attacking her and increases her dodge by X%

W: Toxic Slide-Gwendolyn makes a sliding dash towards the target, leaving acid in her steps, damaging all enemies in her path. Has to have a target to move (ally or enemy, enemy takes damage)

E: Performance- Gives herself and nearby allies increased movement speed.

Ultimate: Twist- Gwendolyn performs a grander Toxic Slide, allowing her to perform it 3 times and spin and kick the enemy champions caught in the hit. Leaves a poison trail in her steps and does not have to have a target while spinning.

I imagine her being played as close to Vayne and Eve, in that she is a strong fighter but somewhat fragile without her team. Her role in teamfights would be to continously get in get out and divert their attention while her team deals with the others. Her skills give her speed so focus should go on ad and as build, though some more speed wouldn't hurt. I also imagine that she can benefit slightly from some AP for her poison though it isn't her primary form of combat since it's more of an aftermove.

Any tips or advice would be greatly appreciated.
