So instead we have a specific part of the military that is specialized in Arena duels (think gladiators). The leader of the military class is an excellent lancer (spear user) and has not been defeated yet in the Arena.
The leader of the Inquisition is a used-to-be military from the special duelist division and a very good one. I want her to have a very specific fighting style using a whip that is tied to her wrist and the handle of her sword (a short double edged sword but you may change it).
The point is that the short sword gives her the upper hand in close quarter combat but if there is enough space (the Arena is a circular wide and plain field like a coliseum) she can also use the whip to lash her sword from afar.
Would this style of fight be any good in 1 on 1 combat? Would it be enough to have her overcome the range difference against a very skilled spear user?
About the user : Woman. age 26. Has been trained to fight since childhood. Fights thugs in back alleys on a weekly basis. Has a small healing factor so getting wounded often but not dramatically is not a big deal.
About the sword : Preferably double edged. The metal can be something modern (e.g: Carbon, Steel, etc...). It can be a bit heavy, she is trained to swing it around. I am originally thinking about something like a Jian
The whip would be around 2 meters long.
The sword would actually be around 1kg
