Pillager Outpost Finder
Edition
Version
Seed
On Java an outpost will not generate within ten chunks of where a village could go, so outposts always stand a little way out from villages.
Pillagers keep spawning around them, which makes them the start of a raid farm, and their cages hold allays.
On Java Edition, type /seed in chat (it needs cheats on, or operator rights on a server). On Bedrock, open the world's settings: the seed is listed under Game.
