A duel between an old man with a sword versus a young man with a sword.
This is Netflix Geralt with his regular sword and armour loadout. He has a few potions on his person.
This is current Shin as of the start of the current arc, in armour but armed only with his normal sword rather than Ouki's glaive.
The battle takes place in the throne room of the Kingdom Qin but it is deserted.
For the purposes of this thread, Shin is considered too strong willed to be swayed by Geralt's mind magic. All other forms of his magic are in play.
Who wins this duel between practical hard-bitten swordsmen?
