Prodigy Fencer

With your history and upbringing in sword dueling you have an advantage in 1v1 melee combat.

if a Nat20 is struck , you and the enemy roll a strength save if you roll higher the enemy is knocked off balance, allowing you to strike them as a reaction

If you fail it is a normal parry and cannot strike.

you also can parry any melee or ranged attack but with increasing difficulty the more you do it.

Melee parry starts at Dex save 10/+1 for every parry

Arrow parry starts at Dex save 13/+2 for every parry

Bullet parry starts at Dex save 15/+3 for every parry

(Parrying doesn't cross Ex[Blocking a bullet or arrow can't decrease your odds of melee parry])

When a Nat20 is struck the only attack that can be made against a knocked back enemy is a sword slash.
