Patrol



A patrol or pillager patrol is a rare, naturally-spawning group of pillagers. On Hard difficulty $$, a patrol can include vindicators.

Spawning
Patrols spawn as a group of 5 pillagers $$ or 2–5 illagers $$ (all pillagers except in Hard difficulty, which has a 20% chance for any pillager to spawn as a vindicator instead), one of which is the patrol captain. The patrol captain wears an ominous banner, known as the  illager banner in Bedrock and Education Editions, on its head. The other illagers follow the leader.

$$, patrols never spawn if   is set to false.

Conditions
Patrols spawn naturally after the world age reaches 100 minutes (5 in-game days), then after a delay between 10–11 minutes an attempt is made to spawn a patrol with 20% chance of success. After an attempt is made, the delay is reset.

Java Edition
Patrols spawn in any biome except mushroom fields and its variants. If a player is too close to a village, patrols do not spawn.

Bedrock Edition
$$ patrols spawn around 24–48 blocks away from the player (or more than 48 blocks away if the player is in a village) in any biomes except, , and. Additionally, patrols can spawn in biomes where common monsters cannot spawn such as in:

Patrols spawn on solid blocks at light level 0–7 at the surface, like monsters.

Behavior
Patrols seek villages, wander around, and attack nearby players, adult villagers, iron golems, snow golems and wandering traders. The patrol members' heads turn to follow a player or villager-like mob who looks at them or attracts their attention. A player or villager-like mob who approaches within 10 blocks of the patrol provokes them into loading their crossbows and attacking, and pursuing if the player flees. The pursuit lasts until either of the parties dies or gets 10 blocks away.

$$, any illagers, ravagers, or witches that did not spawn with the patrol can join the patrol if sufficiently near a patrol captain. Evokers and illusioners who join a patrol wander around but do not seek out targets as other illager members in the patrol. They still do cast spells to attack mobs, however. If a "Johnny" vindicator joins a patrol, all patrol members assume the Johnny vindicator's aggressive behavior, attacking any non-illager mob.

$$, when one of the patrol members is attacked, it alerts nearby patrol members within 10 blocks to attack the same target as a swarm. The attacker can be any mob and doesn't need to be a player, and the distance between attacker and patrol can be up to 64 blocks away from alerted patrol members. Vindicator patrol members attack player and target directly without prior provocation.

The patrol captain always drops an ominous banner, known as the illager banner in Bedrock Edition, upon death.

Bad Omen
Upon killing a patrol captain, the player receives the effect for 100 minutes (displayed as infinite $$), which has no consequences unless the player enters a village. Upon entering a village, the effect is removed from the player and a raid spawns nearby after about five seconds. $$, the level of the Bad Omen determines the chance of enchantment on raid member's weapons, and additional waves. The number of waves depends on the difficulty. The effect can be removed by drinking milk.

Trivia

 * Although patrols cannot spawn in mushroom biomes, they can spawn in nearby biomes and eventually wander into the mushroom biome if the player is inside.
 * In Bedrock Edition, it is possible for patrols to spawn directly inside villages.
