Ravager

Ravagers/Illager Beasts are large hostile mobs that spawn in raids.

Java Edition
Ravagers can spawn starting at wave 2 as part of raids.

Bedrock Edition
Up to 5 Ravagers spawn as part of raid. Unridden ravager spawn at wave 3 and 5, ravager ridden by pillager spawn at wave 5 and 7, and ravager ridden by evoker spawn at wave 7.

Behavior
Ravagers are hostile towards players, iron golems, villagers or adult villagers, and wandering traders within a 16-block radius. They attack by ramming enemies with their head, dealing damage and high knockback. They can also destroy certain block types by charging into them.

If blocked by a shield while attacking, no damage is dealt and knockback is halved. The ravager has about a 50% chance to become stunned and unable to move or attack for around 2 seconds. After this period, it will emit a roar that deals damage and high knockback (which increases with proximity) to nearby entities. The roar can knock back nearby Illagers but doesn't deal damage to them. It can't knock back other ravagers. In spite of this, the ravager does not attack pillagers when they shoot at it, the same applies to the evoker when they acidentally use evoker fang that hits a ravager.

Even though they are heavy, they can swim. Their apparent weight gives them 50% chance of 100% knockback resistance.

Drops
Upon death, ravagers drop 1.

Entity data
Ravagers have entity data associated with them that contains various properties of the mob.

Trivia

 * "Ravager" and "Behemoth" were listed as alternate name suggestions for the illager beast. In Java Edition 19w05a and Bedrock Edition beta 1.11.0.1, illager beasts were renamed to ravagers.
