Illager

An illager is a type of hostile mob that regularly spawns in woodland mansions, patrols, raids, and pillager outposts. All illagers are hostile towards players, villagers, wandering traders and iron golems. Illagers look like villagers, except that they're grey and pale with "L" eyebrows.

Illager types

 * &mdash; summons vexes and evoker fangs. Spawns in woodland mansions and raids.
 *  &mdash; attacks with a bow, may inflict Blindness for 20 seconds and summon duplicates while becoming invisible. They can spawn only using command.
 * &mdash; the most common Illager. Attacks with a crossbow. Passive when unarmed. Spawns in patrols, pillager outposts, and raids.
 * &mdash; attacks with an iron axe; breaks wooden doors in normal or hard modes during raids. Spawns in woodland mansions or raids.
 * Sometimes they may spawn in patrols, in Hard difficulty.
 * only an illager $$ &mdash; attacks by ramming with its horns and sticking its head forward. Roars after its attack is blocked by a shield, knocking back nearby mobs, and dealing damage. Spawns in raids, sometimes ridden by another illager.

Specific criteria
There are three specific criteria for a mob to be considered an Illager:
 * "Johnny" vindicators do not attack the other mob.
 * The mob cannot be damaged by evoker fangs or ravager's roar.
 * The mob does not fight back when hit by a missed arrow shot by a pillager or illusioner.

Non-illager monsters that spawn in raids

 * &mdash; not an illager $$ because "Johnny" vindicators attack them without being attacked by the ravager in return.
 * &mdash; "Johnny" vindicators attack them. They spawn when summoned by an evoker. In a raid, they are not counted in the bossbar.
 * &mdash; Witches are not considered illagers, nor are they hostile to villagers. A villager transforms into a Witch if they're struck by lightning. However, they can join patrols or spawn in raids above normal difficulty and splash Potions of Regeneration or Healing on illagers.. Witches can also spawn in swamp huts or rarely at night. "Johnny" vindicators attack witches, and they take damage from evokers' fangs and ravagers' roars. If a witch's negative splash potion hits another illager by accident, all the illagers in the area attacks the witch, starting a fight. Any witches that are damaged by a ravager's roar, evokers' fangs, pillager's arrow or a illusioner's arrow throws negative potions on that illager that hit it. Witches are also neutral to iron and snow golems.

Ravager Jockeys
A ravager jockey is an illager that spawns riding a ravager. The riders are illager especially pillagers,  vindicators, and  evokers.

Java Edition
A ravager ridden by  pillager spawn at raids in Wave 5. Ravagers ridden by vindicators and  evokers spawn at Wave 7.

Bedrock Edition
A ravager ridden by  pillager spawn at raids in Wave 5 and 7, ravagers ridden by  evokers spawn at Wave 7. The ravagers ridden by vindicators do not spawn on raids, but can be spawned via commands.

Occurrences
Illagers spawn naturally in patrols and raids. They always spawn naturally in groups while in patrols and raids, or inside their structures.

Only the pillager, vindicator, and evoker spawn naturally.

Vindicators and evokers that spawn naturally in s do not despawn and respawn. They are also passive on peaceful difficulty.

Ravagers spawn exclusively in raids.

Raid captain
Illagers sometimes have their own leader. Any illager has a small chance to be a raid captain with an (even when summoned by commands, or when using a spawn egg).

Event
Illagers have their own in-game events, led by raid captains:
 * s &mdash; a naturally spawned group of five pillagers roaming the landscape. The group can include a vindicator on hard difficulty $$.
 * &mdash; a wave after wave of illagers and witches spawn and attack a village with ominous horn blares. An Illager captain spawns in each wave with other illagers, mostly with a vindicator being the captain. It is triggered when a player with the status effect enters a village. Raiders and villagers usually have different behavior in a raid. In Bedrock Edition, any killed raiders drop special loot. Raiders celebrate after defeating a village.

Effect
Killing a raid captain in patrols, in a mansion, or in an outpost inflicts the player with the effect, which triggers a raid when that player enters a village with the effect still active.

Java Edition
Vindicators can open doors like villagers during raids. They can sometimes break a wooden door in normal or hard difficulty, if they cannot open the door successfully.

Illagers, ravagers, and witches do not retaliate when hit by a missed arrow shot by a pillager or illusioner.

A vindicator can disable the player's shield with its iron axe attack, even when riding a mob. If a player fails to land a melee attack on a vindicator that rides a ravager during a raid in Hard difficulty, the vindicator rider can deal great damage to a player without protection from a shield.

During raids, Illagers pick up ominous banners dropped by raid captains who dies in this wave. But won't pick up the banner from last wave remains or throw from player.

All illagers, ravagers, and witches gain 3 seconds of themselves when the bell rings.

Reinforcements
Like Zombies. On all difficulty levels, damaged illager mobs call all other same type illagers within a 67×67×21 to 111×111×21 area centered on the attacked illager to target the attacker. For example, pillagers attack a skeleton that injures another pillager, but pillagers do not aid a vindicator hit by a skeleton.

Bedrock Edition
All illagers and vexes ignore baby villagers, but still may hit them by accident.

A dispenser can equip an illager with armor. However, only helmets and chestplates are visible on pillagers and vindicators, while evokers never have any armor visible.

Pillagers and ravagers do not purposefully attack other illagers. However, non-pillagers and non-ravagers do attack pillagers who hit them with missed arrows. vindicator and evoker retaliates against a pillager if the pillager accidently hits the vindicator or evoker with an arrow. Although the evoker fang won't deal any damage to pillager, Vexs summoned by injured evoker can still attack the pillager.

A "ravager with vindicator rider" is unused $$. It can be summoned by a spawn event command without raid configuration.

After Texture Update, illagers still use the java 1.14 snapshot texture, including some of the marketplace textures (for example, vindicator's eyes and pillager's arms). Also Ravager's legs texture is different that Java edition.

Trivia

 * Illager structures are always themed around dark oak wood.
 * All illagers' eyes are green with the exception of vindicators, which have blue eyes. In the Texture Update, vindicators and illusioners were changed have to green eyes, but in the Java snapshot 18w47b the color of the vindicator's eyes was turned to blue again. This might be a reference to The Shining Easter Egg for the "Johnny" vindicator.
