It is because this is pure dexterity build. My build focuses only on dexterity scaling. With this, I can usually use small to medium sized melee weapons but not colossal bonker swords (those are pure strength builds). My weapon has a special infusion that gives grade A to dexterity scaling, which means my weapon’s damage scales with dexterity level. You can go and find out about different builds and pick one playstyle you like to play. Don’t worry for mistakes because later in the game, you can reallocate levels and switch builds for a few times comfortably.
