Barter

You can find bound merchants at bandit outposts. Free them, and they will follow you back to your base, where you will need to build a dedicated room for each one. The mechanic is inspired by the traveling merchants in Terraria, but each NPC has a distinct personality as well as hunger and happiness meters. Feed and care for the merchant; the higher their happiness, the greater the discounts and the rarer the items that appear in their regularly updated inventory. Currently, the mod features two unique merchants, but more will be added soon.
