Pillager

"Aaah, the village. Once a place of peace, a nexus of happiness, a safe haven for everyone to soothe their souls in a never-ending mantra of “HRMM!”. Who in their right mind would dare to ruin this sanctuary of perfect balance? Now, the easy answer would be the crossbow-wielding Pillagers – the all-new threat of the Village & Pillage update."

- Per Landin

Pillagers are illager mobs equipped with crossbows.

Patrols
5 pillagers spawn in patrols. Patrols spawn naturally throughout the night but after 5 in-game days. They spawn independently of structures, including villages and illager outposts (i.e. they will still spawn in a "no structures" world).

$$ patrols spawn 2–5 illagers; on easy and normal difficulties all illagers are pillagers, while on hard difficulty 80% will be pillagers and 20% will be vindicators, spawning 24–48 blocks away from the player. On easy difficulty, they can only spawn at light level 0–7 while in normal and hard difficulties they can spawn in any light level after 5 in-game days.

Pillager outposts
Pillagers naturally spawn within a 64&times;64 block area around pillager outposts.

Raids
Pillagers are able to spawn as part of raids, as the most common mob in one. Raids start when a player enters a village with Bad Omen.

Behavior
Pillagers are armed with crossbows and attack by shooting arrows at nearby players, iron golems, villagers, and wandering traders. In Bedrock Edition, pillagers don't attack baby villagers. They shoot an arrow every 3 seconds up to 8 blocks away. This can lead to pillagers battling neutral/hostile mobs due to an arrow hitting the wrong target, though pillagers will never attack each other.

Pillagers will switch to melee attack when fully submerged underwater and do not attack when they don't have any weapons.

Celebrating
If raiding pillagers kill all the villagers in a village $$, the pillagers will celebrate their victory by jumping and laughing.

Reinforcements
$$, pillagers are able to spawn reinforcements similar to zombies.

Drops
Upon death, pillagers drop:

It will have a random durability, and can be enchanted at level 5–19 whether or not it was enchanted when it spawned.

Bad Omen
If the player kills the pillager wearing a banner on its head, the player will receive the Bad Omen status effect. These pillagers are patrol/outpost captains.

Patrols spawn a single captain, while outposts can spawn 1-3 captains. Those captains will give the Bad Omen effect at level 1, whereas Illager captains in raids do not give Bad Omen. The effect lasts for 100 minutes (5 days in-game) and will stack to a maximum of level 6 (without using commands), but can be removed by drinking milk.

The higher the Bad Omen effect, the more additional waves will appear in a raid.

Data values
Pillagers have entity data associated with them that contains various properties of the mob.
