Minecraft Preview 1.20.40.20

Cartographers now sell 7 new maps: Desert Village Map, Jungle Explorer Map, Plains Village Map, Savanna Village Map, Snow Village Map, Swamp Explorer Map, and Taiga Village Map.

Armorer

The Armorer's trades have been updated with many changes.

The biggest change is that buying diamond armor now requires paying a small amount of Diamonds as well as Emeralds. This is meant to make the Armorer's diamond armor trades less useful at the start of the game when players don't have any Diamonds, while still giving a powerful advantage to advanced players who have spent some time collecting Diamonds.

Early-game players will find Armorers useful as a great source of iron armor, Shields, and Emeralds.

Other changes include:

• Most master-level Armorers buy Iron Blocks (and pay very well for them)
• Chainmail armor is exclusively sold by the secret Jungle and Swamp Armorers
• The Savanna Armorer sells cursed diamond armor at reduced prices
• The Taiga Armorer can swap one piece of diamond armor for another

Structure Loot

Certain Enchanted Books now have a high chance of generating in some structures:

• Ancient Cities: Mending
• Mineshafts: Efficiency (I to V)
• Pillager Outposts: Quick Charge (I to III)
• Desert Temples: Unbreaking (I to III)
• Jungle Temples: Unbreaking (I to III)
