Usually use the Claymore although sometimes I have found myself swapping to Silv. Kn. Sword for some faster attacks. The 40/40 Str/Dex make the Claymore usually swing for 390 1H or 520 2H and that without buffing with Charcoal or Gold Pine resin. The Dark Silver Tracer has the highest crit multiplier which makes it an excelent choice for PvP. A parry riposte usually hits for over 950 which can be boosted even further with Hornet Ring (around 1200) When invading chameleon always comes in handy in order to surprise the host. Once fighting I swap the catalyst with a pyro flame. If dueling you can use both spell slots for Great C. Fireball since you don't need Chameleon.
