Bad Omen

Bad Omen is a status effect that causes a raid to appear when an afflicted player enters a village. This does not apply to any other mob with the effect if the mob is in a village.

Getting Bad Omen
Bad omen can be inflicted only on players and tamed wolves when they kill an illager captain (except those that spawn in raids in Java Edition). A tamed wolf killing an illager captain gives their player the bad omen effect. Other mobs that kill an illager captain do not get the effect, although they can still get the effect via commands, but cannot start a raid when in a village. This also goes for any other illagers that kills an illager captain, including arrows shot by a pillager or an illusioner.

An iron golem that kills an illager captain does not receive the bad omen effect.

Effect
$$, Bad Omen's potency determines the chance for illagers to be equipped with enchanted weapons when the player triggers a raid by entering a certain radius around a bed that a villager has claimed. If the raid results in player victory, the Hero of the Village's potency equals the Bad Omen's potency (capped at level 5). Bad Omen levels past the first also give a single extra raid wave, given the difficulty level. For example with Bad Omen II-V in Easy difficulty has four waves instead of three, Normal difficulty has six waves instead of five, and Hard difficulty has eight waves instead of seven.

$$, regardless of Bad Omen level, it always has the same effect. It does not trigger raid mobs getting enchanted weapons or an extra wave. Once the player gets the Bad Omen effect $$, an animation similar to the one displayed when dying with the totem of undying appears, showing the effect's symbol rotating on the screen.
 * The same applies when receiving the Hero of the Village effect.

Bad Omen is a status effect and can be removed through all conventional methods, such as drinking milk or dying.

The player can still receive the bad omen effect in peaceful difficulty via commands (all illager captains despawn in peaceful), but does not trigger a raid if in a village.

Immune mobs
Only boss mobs are immune to Bad Omen; however, only players and tamed wolves can trigger raids, other mobs with bad omen while in a village do not trigger a raid.

Trivia

 * If the player leaves a village during a raid, receives Bad Omen, and returns to the village, the effect is removed but does not affect the existing raid.
 * A player cannot receive Bad Omen when indirectly killing a Patrol Captain. This includes burning with fire or lava, thorns damage, drowning, explosions, and suffocation, among other things. This also includes killing a captain with fireworks shot from a crossbow.
 * If the player kills a captain while in a village $$, the animation, raid bar, and Bad Omen effect appear simultaneously. The effect disappears immediately after, then "flashes" again approximately 1 second later.
