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

A pillager is an illager equipped with a crossbow.

Patrols
Five pillagers spawn in patrols. Patrols spawn naturally after 5.5 in-game days. They spawn only at night independently of structures, including villages and pillager outposts (i.e. they still spawn in a "no structures" world).

$$ patrols spawn 2–5 illagers; on easy and normal difficulties all mobs are pillagers, while on hard difficulty 80% are pillagers and 20% are vindicators, spawning 24–48 blocks away from the player. On easy difficulty, they can spawn only at light level 0–7 while in normal and hard difficulties they can spawn in any light level after 5.5 in-game days.

Pillager outposts
Pillagers naturally spawn and respawn within a 71&times;71&times;71 block area around its pillager outposts.

Raids
Pillagers are able to spawn as part of raids, as the most common mob in one.

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, following the foe for up to 12 blocks. Pillagers never attack one another.

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

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

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

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

Patrols spawn a single captain, while outposts can spawn 1-3 captains. Those captains 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 stacks 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 appear in a raid.

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

Trivia

 * I pillager's crossbow eventually breaks if the pillager shoots at the player repeatedly, leaving the pillager with no method of attacking. This causes its behavior to change as well; it walks at random similarly to passive mobs, but always faces any player in the pillager's field of view. The pillager also always holds its arm up, similar to an attacking vindicator.
