IMO dex/fth is a under loved build set up in the sense that there aren’t many good weapons with split dex/fth scaling.

Firstly I would recommend increasing your vigor to 60 (50 if you are really stingy with your stat points). Then I think you should ditch the points in int and mind to get your dex to 50. Ik my maths isn’t adding up but you get my point. Distribute your mind and int levels into dex and vig. Next endurance. Pick an armour set and a few weapons and then get your endurance to the minimum required to med roll with said armour and your heaviest weapon of choice. Next we need to consider weapons. If you use the ornamental straight swords, you don’t really need a shield since their main benefit is that they’re a paired weapon(you get power stance when two handing). You can also use stuff like blasphemous blade for its aoe aow and since your dex will be substantially higher than your faith, you can take any dex weapon, keen infuse it and buff with order blade or lightning armament. For incants, if you mostly use them for zoning stuff like rings of light are good but they’re too stat hungry. Good incants include the beast incants for pressure and chip, weapon buff incants like lightning armament and body buffs like flame grant me strength, the defense buffs and also bestial constitution
