Perfect Blade

Those who dare choose the way of the Perfect Blade throw away their rationality, humility & compassion so that their senses may sharpen, their swordplay transcends & their ego eclipses that of the Gods.

Vespertine

Your Fighting Style becomes Dueling, you cannot change it, you cannot dual-wield & use other weapons besides Rapier, Shortsword or Dagger

Narcissistic

You cannot wear anything that covers the head or face -2 AC to your total AC.

Deftness Parry

Spend an Action to use this skill, when you do you ready yourself into a bellicose stance granting you a free Melee Attack against other Melee Attacks directed at you in range; up to a limit of 3 times until the start of your next turn. Every Fighter level after this increases the limit by 1 per level. You may only use this feature twice, afterwards you must finish a short or long rest before you can use it again.

Duelist

At the 7th level, you may add half your Dexterity bonus (rounded up) to Melee Damage & +4 AC when you are engaged in single combat; if your opponent is armed gain +6 AC instead.

Ghostly Beauty

You cannot experience fear if you don't exist. At 10th level, you gain Advantage against the Frightened condition & Fear spells but you suffer Disadvantage against other Wisdom Saving Throws; consuming flower petals negates the Disadvantage. Additionally, if you suffer any injury to your face you become Incapacitated for a round as you feebly feel to make sure that they didn't leave a lasting scar.

Petal Spiral

At 15th level, you become addicted to consuming flower petals. If you do you gain the knowledge of what the petals tells you, Immunity to Frightened & Expertise on all proficiencies for 3 hours. If you don't consume any flower petals within 12 hours, your senses dull & movement becomes sluggish. Make a d5 roll & subtract that score from every tests made for now on, repeat this every 24 hours, it stacks; consuming flower petals resets it.
Up to DM Discretion on what knowledge you gain, whether it'll be helpful or unfavourable. Flower petals must not have wilted. Expertise doubles your Proficiency.

True Blade

Starting at 18th level, you have attained Perfection. Double your Proficiency Bonus for Melee Attacks. Your total Critical Hit damage is doubled.
This also stacks with Petal Spiral so at level 18 your total Proficiency Bonus is 24.
