You are no longer in stance if you go incapacitated, or if you are made prone and you can end it if you use a bonus action.

Strike like Steel

At 7th level, your fists strike similar to an actual weapon making it so when you have entered your stance you cause your unarmed strikes to overcome Resistances and Immunity by making it magical and granting a bonus to To Hits and Damage equal to half your Proficiency and you can treat your unarmed strikes as either Bludgeoning, Piercing, or Slashing damage rather than Bludgeoning damage.

Great Weapon Fighting

When you roll a 1 or 2 on a damage die for an attack you make with a melee weapon that you are wielding with two hands, you can reroll the die and must use the new roll, even if the new roll is a 1 or a 2. The weapon must have the two-handed or versatile property for you to gain this benefit.

Perfected Fists

At 18th level, your mastery over hand to hand combat has exceeded even your own expectations. While you are in your stance you can treat your fists as if having two of the available weapon properties instead of just one. You no longer lose your stance when you are made prone and you can choose to end your stance as a free action on your turn.
