A free mod for Witcher 3, by stefan3372.

Lore-Friendly Economy is a free, simple, and fun mod for the popular RPG game, The Witcher 3. The goal is to modify the prices and cost of all items in the game, trying to stay within the lore as much as possible. This is done by changing the prices of items, both while you’re selling or buying them.

This mod makes the prices follow the quest rewards that you will be able to get in an area.

You won’t need to change the game settings or add any items or weapons to your inventory.
