It's possible to Parry your entire stamina Bar for myself and some of my dueling partners. I think a lot of the Vets are at this level as well. It's honestly not hard to do or even impressive, so to land a hit you basically cheese the animations and try to hide your arm from your opponent, it's the only way unless your opponent messes up and you catch them with a bait. Or maybe you could add a Skill called Trade Offense that increases Speed of your attack while opponent is attacking and adds a tiny bit of chip damage? Just my 2 cents, people keep telling me Mordhau combat is similiar to Mortal but doesn't let you parry a lot or something.
