Your worst enemies, your best workforce.
PillagerControl lets you capture pillagers and turn them into workers - as long as you feed them.
Brew a Potion of Thrall (Ominous Bottle + red mushroom) and splash it on a pillager: he puts his crossbow away and stops attacking for 10 minutes. Leash him, park him at a fence, walk him home. Find him a job before the effect runs out, or he goes back to his old ways.
Place a job block near a pacified pillager and he claims it, outfit and hat included:
Workers eat one cooked meat per game day. Build the 3x3x3 spruce canteen pattern, throw a splash Potion of Thrall at it, and it assembles into the Mess - a 27-slot pantry with a 32-block feeding radius. At dawn, hungry workers walk over, grab a meal and eat it on the spot.
A shaking worker is hungry. Keep the pantry stocked, because...
A hungry worker revolts at an unpredictable moment within the next game day. The more hungry workers share a Mess, the sooner it blows up - and one hostile pillager entering the zone triggers a full uprising instantly. Rebels drop their tools, draw their crossbows and remember whose side they were on.
Craft the Pillager's Handbook (book + red mushroom) - a full Patchouli guide with the multiblock visualizer. English and French included.
