You might be looking to manipulate the economic market in Dragon's Dogma 2, and that's where the Item Tweaks Mod from Synthlight comes into play. Players can select from various modifications including setting purchase costs to 1 Gold, increasing sell prices tenfold, eliminating item weight, or combining these features in various ways for specific item categories or universally. You can buy your favourite weapons for 1 gold piece, or sell terrible weapons for 10x the price, for example. Really useful.
