If you want to, the Dragonslayer can be replaced by any other dex weapon, i personally recommend the Falchion, since thanks to the Darkmoon blade buff it can get a very big buff m8, anyways the Painting Guardian Sword is better for the bleed effect but the range... ugh.
Other cool weapon is a rapier m8, with that weight you can use the Magic warrior's round shield and the iron bracelets for 32 poise m8
