Vendor recipes allow you to trade specific combinations of items to NPCs for valuable currency or unique items. Famous examples include the 'Chaos Recipe' (full set of rare items for a Chaos Orb) and the 'Regal Recipe' (full set of rare items for a Regal Orb). There are also recipes for 6-socket items, 6-link items, and specific unique items. Learning these can be a consistent source of early game currency.
