The way this Build works is that you'll be using Dynast's Finesse during your tough enemy and Boss fights, while using R1 and R2 attacks on trash enemies to conserve FP.

Dynast's Finesse allows you to i-frame though attacks much more easily than dodging, and it can be used with maximum equip load, meaning you can wear extremely heavy armor if you wish, particularly because you will need high Endurance for this Build.

The follow up attack of Dynast's Finesse will get you back into melee range, and does significant Stance Damage, allowing you to stagger enemies quite easily. Further attacks usually trigger Hemorrhage, which will proc your Attack Power buffs from Lord of Blood's Exultation and White Mask, allowing you to pump out even more damage as the fight goes on. When the enemy counter attacks, simply use L2 again to i-frame away and repeat this process.

Dynast's Finesse uses considerable amount of Stamina to both spin away and attack, so you need TONS of Stamina to be able to maneuver as much as you want with this Build. This is why have high Endurance, use the the Green Turtle Talisman, and Viridian Amber Medallion and you could even use the Green Turtle Shield on your back for more Stamina regen.
