Minecraft has many effects players can activate. You can even have all the status effects activated simultaneously in Minecraft with the “How Did We Get There?” advancement. “.
Effects in Minecraft are activated by players who consume a potion. There are some effects that can be activated in different ways. Bad omen can be applied only to players and tamedwolves, unless the player gives permission.
A player or a tamed Wolf can acquire the bad omen effect by killing an illager captain. This effect only occurs if the illager is not spawned during raids. The appearance of the illager captain is identical to that of normal illagers, but the banner has a pillager-like face design.
A player can find an illager captain in raids. It is either a captain of a pillager outpost, or it is patrolling with some other illagers. Once they have obtained it, an effect icon will be displayed at the top of the screen.
Raids are triggered when a player with bad omen effects enters a chunk that has at least one villager or a claimed bed.
Bad omen potency can also affect the likelihood of illagers being spawned with enchanted weapons after a raid is activated. Bad omen level also affects the number of waves that a raid will have.
After an hour and forty minutes, the bad omen effect is automatically removed. It is much easier to manually remove the bad omen effects than most people think.
