Pillager

A pillager is an illager equipped with a crossbow.

Patrols
5 pillagers spawn in patrols. Patrols spawn naturally after 5$1/2$ in-game days. They spawn only at night independently of structures, i.e. they still spawn in a world without generated structures.

Patrols spawn 2 to 5 mobs; on easy and normal difficulties, all are pillagers, on hard difficulty 80% are pillagers and 20% are vindicators, spawning 24 to 48 blocks away from the player. On easy difficulty, they spawn at light levels from 0 to 7, while in normal and hard difficulties they spawn in any light level after 5$1/2$ in-game days.
 * Bedrock

Outposts
Pillagers naturally spawn and respawn in outposts. They spawn in a 72&times;54&times;72 block area centered on the top floor (with the chest). Only pillagers can spawn in that area.

They need a block light level between 0 and 8 inclusive. Unlike for regular hostile mobs, higher light levels within that range do not reduce probability of successful spawn. Additionally, unless the block underneath is a grass block or sand, they need sky light level of no more than 11, after adjustment for nighttime and weather.

They spawn at or below a particular location in the outpost, choosing the highest opaque block with a non-solid block on top and spawning on the northwest corner.
 * Bedrock

Raids
Pillagers spawn as part of raids, as the most common mobs in one.

Behavior
A pillager is armed with a crossbow and shoots arrows at players, iron golems, snow golems, wandering traders and adult villagers. They shoot an arrow each 3 seconds up to 8 blocks away, following an enemy within 64 blocks. Pillagers never attack one another; even if one is shot by another pillager, it does not start dueling.

It uses melee attacks when underwater.

If raiding pillagers kill all the villagers in a village, the pillagers celebrate their victory cheering.

Drops

 * A loaded or unloaded, which has an 8.5% chance to be dropped; this rate increases by 1% per level of Looting.
 * It has a random durability.
 * A pillager has a 0 to 10% chance of having a crossbow enchanted at level 5 to 19, both depending on regional difficulty.
 * and an additional per naturally-spawned equipment when killed by a player or tamed wolf.
 * 1 Illager Banner.png Ominous banner, if the pillager is a raid captain. The raid captain spawns with an ominous banner above its head and always drops the banner when defeated.


 * Bedrock special drops


 * 0–2 s, dropping more with the presence of Looting, up to 5.

Pillagers spawned by raids drop:
 * 0–1

Notes:
 * Iron equipment drops from raids always has a 50% chance of being enchanted with a random enchantment level from 5 to 19. A pillager may also have enchantments on books and armor that cannot be normally obtained, such as blast protection and fire protection on the same pair of boots.
 * Iron equipment is always damaged, having from 30 to 90% of the full durability.
 * These drops are affected by the Looting enchantment.
 * Emeralds are both a regular raid drop and an additional drop.
 * Enchanted books have a level 30 enchantment and also can be a treasure enchantment.

Bad Omen
If the player kills a 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 at a time. These captains give the Bad Omen effect at level I, 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

 * $5/78$, a 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 its field of view. The pillager also always holds its arm up, similar to an attacking vindicator.
 * No other mob runs out of durability on their weapon. For example, a skeleton or illusioner could shoot arrows forever, as their bow does not lose durability.
