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.

Spawning
Pillagers only spawn at a pillager outpost, as part of an illager patrol, or during a raid.

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

$$, pillagers can spawn in illager patrols. Illager 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. The illagers will spawn 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 in and around pillager outposts.

Raids
Pillagers are able to spawn as part of raids, usually as the most common mob in one. Raids start when a player enters a village with Bad Omen which is obtainable from killing a pillager captain from a pillager outpost or a patrol.

Behavior
Pillagers are armed with crossbows and attack by shooting arrows at nearby players, iron golems, villagers, or adult villagers, and wandering traders. They shoot an arrow every 3 seconds at 6 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 can ride ravagers. Pillagers will attempt to specifically target villagers in a raid while they will run away from the pillagers and will change targets if an entity hits them within their firing range.

Pillagers will switch to melee attack when fully submerged underwater.

They don't 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:
 * 0–2 s, dropping more with the presence of Looting, up to 5.
 * Its (can be loaded or unloaded), which has an 8.5% chance to be dropped; this rate increases by 12% per level of Looting (20.5% with Looting I, 32.5% with Looting II and 44.5% with Looting III).

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 along with other Illagers, while outposts can spawn up to 3 captains. Patrol/outpost 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. $5/78$, 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.
