Ravager

Ravagers are large hostile mobs that spawn in raids.

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

Behavior
Ravagers are hostile towards players, iron golems, villagers or adult villager, and wandering traders within a 16-block radius. They attack by ramming enemies with their head, dealing damage and high knockback. They will also destroy crops and leaves that they run quickly into, though flowers, saplings, and crops such as melon and pumpkin stems are unaffected.

If blocked by a shield while attacking, no damage occurs 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 does damage and high knockback (which increases with proximity) to nearby entities. The roar can knock back nearby Illagers but dont damage them, also another ravager cannot be knockbacked. In spite of this, the ravager does not attack pillagers when they shoot at it, the same also when evoker acidentally use evoker fang that hit 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.
