Minecraft wiki entry for Raid, associated text: In Java Edition, besides triggering a raid, the Bad Omen status effect's level of the triggering player also affects the raid mechanism. When the Bad Omen level is higher than one, an additional wave spawns with the same strength as the final wave. With a higher level of Bad Omen to a raid, the illagers in the raid have a higher chance of being equipped with enchanted weapons. Players can also drink milk to remove any level of the Bad Omen effect. In Bedrock Edition, Bad Omen does not affect the enchanted weapons.
