How Trading Works

The Weaponsmith villager sells enchanted common melee weapons at Level 4 / Master for 12+ emeralds, and enchanted unique melee weapons at Level 5 / Expert for 24+ emeralds. The same goes for the Fletcher, Armorer, and Leatherworker, but for ranged weapons, metal armors and non-metal armors respectively.

In addition, you may shift right-click a Weaponsmith to salvage a common melee weapon for 2-6 emeralds or a unique melee weapon for 4-12 emeralds. The same goes for the Fletcher, Armorer, and Leatherworker, but for ranged weapons, metal armors, and non-metal armors respectively.

The Wandering Trader will sell you a random artifact for 24 emeralds. You may also shift right-click them with an artifact to salvage it for 4-12 emeralds.

These features are configurable in terms of the prices as well as the activation/deactivation of the trade changes.
