Notes from author
Quick, punishing build, utilizing mainly the Ricard's Rapier. The rapier is great for fixed buffs, such as Darkmoon/Sunlight Blade and Crystal Magic Weapon, due to it's quick succession heavy attacks (though, I'm unfamiliar with Ricard's Rapier, as I rarely use it, so I'm not sure what it's capacity for guard break or poise break is). Balder Side Sword for it's power and diverse move set. Darkmoon Blade/Talisman for the overpowered buff on Ricard's Rapier. Wanderer set for a good protect rating with low weight. Any shield will do, 6 units or less: so grab a Black Knight shield or Silv. Knight shield, since they boast high Stability (and the BKS has the highest Fire protect, at 95% reduction). This build is something of a template, and it to be built off of, add Endurance and Vitality, since you already have high damage from the Rapier+DMB and (Ltng.) Balder Side Sword.
Good Luck, and Happy Hunting.
