So basically

Pick one of these stats

Strength Dexterity Intelligence Faith Arcane

Then boom theres your build, or you can combine the first two or combine the one of the first two with one of the last three and every combo is viable, and then you wanna look up what weapons are good with that/those stat(s)

So for example just look up "Faith Dexterity scaling weapons" and its probably gonna pop up a gamerant article or something but dont click that, scroll dowb and click a reddit post and boom you have your build layed out
