A Armorer buys Coal, Iron Ingot, Lava Bucket and Diamond for emeralds and sells Iron Helmet, Iron Chestplate, Iron Leggings, Iron Boots and Bell and 9 more — 18 possible trades from Novice to Master.
The Blast Furnace. An unemployed villager that claims a Blast Furnace becomes a Armorer. Break the block before your first trade to make the villager pick a new profession.
Sell it 15 Coal (Novice), 4 Iron Ingot (Apprentice), Lava Bucket (Journeyman) and Diamond (Journeyman). Each of these trades pays emeralds and gives the villager experience towards its next level.
At Master level a Armorer can offer Enchanted Diamond Helmet for 13–27 Emerald and Enchanted Diamond Chestplate for 21–35 Emerald.
18 possible trades: 5 Novice, 4 Apprentice, 5 Journeyman, 2 Expert and 2 Master. A villager does not offer all of them — each trade card shows the chance that it is offered in Java and Bedrock Edition.
