Minecraft wiki entry for Raid, associated text: In Bedrock Edition, when a player with Bad Omen enters a 64x23x64 region around a village center (technically 1.12 blocks below the center), the effect disappears and the raid starts. A bossbar labeled "Raid" appears and begins charging. The bossbar is visible in a 128×88×128 region around the village center (technically 1.12 blocks below the center). The bar is purple, and represents the number of remaining mobs. While a wither is already present in the village and a raid starts, the bar is red and black. It is not clear whether or not this is intentional. The number of mobs still alive displays when there are fewer than three. A horn sounds at the start of each wave, and plays again at intervals until the wave has been defeated, or the player has lost. The horn plays from the direction of one of the illagers, which can help you locate it. The bell rings while the bossbar charges. Each subsequent wave is larger, with more mobs, including pillagers, witches, evokers, ravagers, and vindicators.
