Kimmy: Best build, Counters

Aerial Dominance

Kimmy can move and aim in different directions while using her Spray Gun, but she cannot lock onto a specific target. Each Chemical Bolt deals (+18% Total Physical Attack) (+24% Total Magic Power) Magic Damage. Hitting enemy heroes or non-hero units restores 6 / 3 Starlium, respectively. At max Starlium, she continuously consumes it to enhance her Basic Attacks, making them deal (+22.5% Total Physical Attack) (+30% Total Magic Power) damage and pierce targets (enhanced Basic Attacks only benefit from 50% Spell Vamp).
Kimmy can keep moving while shooting and does not benefit from Attack Speed Bonus. Every 1% Attack Speed gained is converted to 1 Magic Power.
Kimmy's Basic Attacks only deal 60% damage to Turrets.

Anti-Grav Thruster

Kimmy uses her jetpack to take flight, removing and becoming immune to slow effects. She can pass through terrain and gains 120% extra Movement Speed that decays over 1s. During the flight, she continuously fires 4 Chemical Bolts at nearby enemies, each dealing 20 (+25% Total Physical Attack) (+30% Total Magic Power) Magic Damage and slowing them by 50% for 0.5s.

Traction Pulse

CD: 50

Kimmy charges up and fires a Traction Pulse in the target direction. Upon hitting an enemy or reaching its max range, it explodes, dealing 150 (+45% Total Physical Attack) (+54% Total Magic Power) Magic Damage to nearby enemies and creating a force field that slows enemies within by 50%.
After 1s, the field contracts, pulling enemy heroes within it to its center and dealing 15% of their current HP as Magic Damage. It also slows them by 50% for 2s. Each enemy hero hit grants Kimmy 40 Starlium.
