Void Walker

Void Walkers are hostile melee mobs that spawn naturally in the Overworld.

Spawning
Void Walkers spawn naturally in all biomes in the Overworld.

They will only spawn under Y=50, and only in places with a light level lower than 8. Their spawning can be prevented by placing torches or other lighting blocks nearby to raise the light level above 7.

Behavior
Void Walkers are melee mobs that will follow targets both on land and in water. They will initially attempt to avoid getting into the water where possible, but will go in if they find no other path to their target.

They are aggressive, and will attack nearby players within 16 blocks without provocation. If attacked by another entity, they will retaliate and continue targeting that entity.

Staying outside of their targeting range will prevent them from attacking or targeting entities.

Unique Abilities
When a Void Walker successfully attacks an entity, it will apply blindness for 10 seconds.

Hunter Mob
Void Walkers are Hunter creatures that can be killed at any level. When killed, they will grant 6.4 Hunter xp.

Experience
Void Walkers drop experience when killed.
