She wields a beaten revolver in one hand, and a smooth throwing knife in the other. Besides her clothing, she dons a metal vest and an amount of hextech jewelry in her piercings.
The easiest way to describe Ambidexterity's behaviour is as follows: Boom, boom, boom-shk, boom, boom, boom-shk. Note that "shk" is used here to refer to Ambrosia throwing a knife, and the knife attack does not count towards Ambidexterity stacks. This way is probably more enjoyable to play against.
Ambrosia/Wildcat is designed to revolve around her Ambidexterity passive and heavy aggression. She begins the game having a very low range, though this slightly improves as the game goes on.
With Iron Knife, quick trades are encouraged after getting two Ambidexterity stacks from minions. With Leaden Metal, she deals increased damage to low-health targets, encouraging early aggression.
With Sharp Edge, she forces and wins or recovers from trades. With Cutting Eye, she becomes relatively safe only as the game progresses.
With Scapegoat, she leaves no trace of herself at the crime scene. With Dirty Work, neither will her enemies.
Wildcat encourages her to play aggressively and focus on using Ambidexterity upon the correct targets. If the aggression succeeds, she can use Iron Knife with Dirty Work to start in on another target; she can use Sharp Edge and Scapegoat to ensure she can maintain her offense or to escape silently.
