Ravager

"If you take a cow, make it angry, and strap a crossbow-happy Pillager to its back, what do you get? You get a very confused cow. But if you were a development team looking to make a new threat for Minecraft – one that looks a bit like a cow with serious anger issues – you would get The Ravager."

- Ash Parrish

Ravagers are large hostile illager mobs that spawn in raids.

Java Edition
Ravagers can spawn starting at wave 3 as part of raids.

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

Behavior
Ravagers are hostile towards players, iron golems, villagers or adult villagers, and wandering traders within a 32-block radius in Java Edition or 16-block radius in Bedrock Edition. They attack by ramming enemies with their head, dealing a high knockback. They can also destroy certain block types by charging into them.

Whether 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 2 seconds. After this period, it emits a roar that deals damage and high knockback to nearby entities. The roar can knock back nearby illagers without damaging them and has no effect on other ravagers. The ravager does not attack pillagers who shoot at it and does not attack evokers when evoker fangs accidentally hit a ravager.

Even though they are heavy, they can swim. Their apparent weight gives them 50% chance of resisting knockbacks.

A ravager being ridden by an illager dismounts its rider if it moves into water 2 blocks deep.

Ravagers are able to spawn reinforcements.

Drops
Upon death, a ravager always drops one (1) (unaffected by Looting) and 20 experience, the most out of any mob apart from boss mobs.

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.
 * In Java Edition 3D Shareware v1.34, ravagers dropped yellow keys.
 * In Java Edition, evoker fangs can hurt ravagers, so evokers may kill their mounts while riding ravagers. However, this does not happen in Bedrock Edition because evoker fangs do not hurt them.
 * Ravager was mainly inspired by the mythological creature, Manticore, especially the one from Dungeons & Dragons.
 * Ravagers were unused during snapshot 18w46a, but were added as a raid exclusive mob in snapshot 18w47a.
