Ravager

Ravagers are large hostile mobs that spawn in raids and attack players, villagers, wandering traders and iron golems.

Raids
They spawn starting at wave 3 as part of a raid.

Java Edition
Unridden ravagers spawn at wave 3, a ravager ridden by a pillager spawns at wave 5, and a ravager ridden by a vindicator spawns at wave 7. A ravager ridden by an evoker also spawns at wave 7.

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 toward players, iron golems, adult villagers, and wandering traders within a 32-block radius. They attack by ramming enemies with their head, dealing a knockback of 5 blocks. They can also destroy certain block types by charging into them.

Although ravagers are equipped with saddles, they cannot be ridden by the player.

When blocked by a shield while attacking, no damage is dealt and knockback is halved. The ravager also has 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 a knockback of 5 blocks to nearby entities. The roar knocks 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 makes them take 50% less of knockback. A ravager being ridden by an illager dismounts its rider if it moves into water 2 blocks deep.

Drops
A, unaffected by Looting, additionally experience orbs, the most out of all non-boss entities in the game.

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