Crystal Sage catalyst in the left for the extra-powerful spellbuff, Logan's (Court Sorcerer's) catalyst in the right for the base spell damage. It'll get buffed by the CSC, giving you the highest spell damage. Scholar's  Candlestick got nerfed, unfortunately.

If you're using a melee weapon, I wouldn't consider you a pure sorcerer, IMO. Moonlight Greatsword is an obvious fit. Greatsword of Judgment also fits the theme, but battle viability is questionable. Crystal Sage Rapier, as any rapier, will perform just fine, PvE and especially PvP.

Dragon Breath is okay in PvE, Crystal Hail I would discard. Honestly, the various Soul-Spear-esque spells should be sufficient. Maybe with Farron Flashsword for mobs and limited PvP. Don't do PvP, though, don't.
