Pillager

A pillager is a hostile mob that spawns regularly in raids, patrols, and in pillager outposts. It's 2020 now

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.

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 and passive mobs may spawn in that area.

Pillagers may spawn on any valid opaque block as long as the sky light level is above 8, and the block light level is below 8, but can also spawn on grass or sand blocks regardless of block light level.

$$, pillagers 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.

Raids
Pillagers spawn as the most common mob within raids.

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

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

$$, a pillager's crossbow eventually breaks with repeated use, unlike weapons wielded by other mobs. A pillager continues to shoot arrows until their crossbow breaks. An unarmed pillager $$ is passive to everyone, but still frightens villagers. Since it takes 326 arrows to break a crossbow that is unenchanted or only has piercing or quick charge and a pillager fires every 3 seconds it would take 16 minutes and 3 seconds to break a pillager’s crossbow. Each level of unbreaking multiplies the amount of arrows by level+1, and multishot divides the time by 3 (it still shoots the same number of arrows but uses more per shot).

$$, pillagers use melee attacks when underwater.

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 higher chance of the crossbows of the pillagers being enchanted.

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

Trivia

 * $5/78$, an unarmed pillager 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.
 * The command:  summons a passive pillager that does not attack anything.
 * In the Buzzy Bees trailer, a hidden pillager can be seen watching over the villagers.
 * In the same trailer, a pillager comically flees from the bees.
 * Pillagers are the first mobs to wield a crossbow, the second being Piglins.
 * Pillagers are slightly taller than their other illagers and other villager like mobs. (Excluding Witches, who have a hat).
 * This could most likely be a bug.
 * They are the only illager to not fold their arms.
 * The pillager's head looks like the evoker's head.
