Armorers. Where do I even begin! When the speedrunners raid the blacksmiths house and kill the golems, it's up to the players and armorers to bring about peace. Armorers are the last line of defense, putting armor on villagers who need it and giving armor to players who interact with them. They're so good at their job that when villagers are equiped with armor, you can't tell untill they die. Beyond benevolent and often overlooked, the Armorer deserves a lot more respect than it currently has. Stop locking these kind people away in caves, forcing them away from the sun! All they were trying to do was protect you from threats when they weren't around. Justice to Villagers! #help2villagers! Join the Villager Vigilantes and save Villagers!
