Minecraft wiki entry for Superflat_survival, associated text: To make fighting patrols at this stage easier, you can try to get a pillager to shoot a vindicator, which causes it to become hostile to the pillager, allowing for you to dispose of several pillagers without directly fighting them. You can farm arrows, crossbows, and iron axes from patrols, and emeralds from vindicators. To speed up the farming process, you can get more emeralds from vindicators if you are fortunate enough to get a sword with the looting enchantment on it from a zombie or zombie villager.
