Raid

A raid is an in-game event in Minecraft BE2. A raid is where endless waves of illagers spawn. Illagers and witches not spawned as part of the raid (e.g. from a patrol) may join the raid and be counted by the bossbar, provided they are within 96 blocks of the village center. Illusioners can also join the raid. Raid captains may also join but do not trigger a new raid when killed. Witches participating in a raid often help other illagers by splashing a Potion of Regeneration or Healing. Witches participating in a raid also attack the player and iron golems.

Illager Types
Vindicators are the most common mob in a raid, being in the first waves. They appear in every wave. The less common illager is the Pillager. They spawn in every wave but aren't as commonly spawned compared to Vindicators. One of the least common illager is the Evoker. The Ravager and Witches also spawn. Every mob above spawns in every wave. Illagers from Minecraft Dungeons also spawn. As of 1.18.8, Raids now spawn illagers from the Hard Pillage addon!

Waves
Waves are classified as how many illagers spawn at once. They are not counted by the bossbar. The bossbar shows how much morale the Raid has. The Raid has a lot of morale and will regenerate 10 morale per second.

Other Information
Ravagers do not spawn in the first and second wave. Illagers from MCD only spawn starting from wave 5. Bosses and mini-bosses also spawn from MCD.
