The Crystal Rapier (assuming you're going Sorcerer) is a pretty good weapon, with some nice Int scaling. Don't have it, but I heard that a certain scythe from Ashes of Ariandel is good, too, and presumably that lightsaber thing from the Ringed City. The Crystal Chime lets you cast Miracles too, so you can use things like Tears of Denial, and it has a pretty high spell buff, too. Once you start getting higher Intelligence, the Court Sorcerer's Staff has S scaling. Some good spells are Great Heavy Soul Arrow, and Soul Greatsword. Homing Crystal Soulmass is nice too, but imo takes a bit too much Flower Points, for how often it should be used. Farron Dart is also nice, but only for finishing off enemies with low super low health. Finally, it takes a heck of a lot of Flower Points, and is really hard to use right, but Soul Stream looks [b][u]awesome[/u][/b]. Rings that increase attunement, and decrease casting time are recommended, with the Bellowing Dragoncrest Ring, as well. Finally: I am by no means a pro at builds. I can guarantee there are better ones out there, and I've actually been struggling to find a weapon too. Right now I'm using the Dancer's swords, because they're awesome. I also haven't finished Ashes of Ariandel, nor have I played Ringed City yet.
