I don't know much about hexes or miracles other than like heal or lightning spear lol. One of my favorite strength weapons is the great club. I love two handing it and using the strong attack to smash small enemies into the ground lol. It does decent damage to bosses too, it's just slow. If you go for like strength and dex, my second favorite sword in the game is the sun sword. It has A scaling for both so 40/40 in strength and dex gives it a decent punch. It's got a very nice move set too. It also helps that it upgrades to +10 with normal titanite methods and is a faster swinging sword. The only problem would be getting it lol. You have to rank up the sunlight covenant to 20. So you have to be summoned as a sunbro, or summon a sunbro and defeat a boss to get 20 sunlight medallions to level up the covenant.
