Chou tries to be pragmatic, often to a fault. She'll always attempt to identify her foe to determine any weaknesses it may have, then if she possesses one of those weaknesses, move to deploy it as quick as possible. When she can't she usually ducks in and out, taking shots where possible and using her opportune parry/riposte to draw attack, allowing her allies to close in safely.
Note: She can draw her alchemical weapons as a swift action from her cheek pouches, and drink potions as a move.
