Baumba

Baumbas are hostile ranged mobs that spawn in infested asteroid in Lunalus.

Space Arenas
Baumbas will spawn continuously from the 2 spawners generated within each infested asteroid.

Their spawning can be prevented by placing torches or other lighting blocks nearby to raise the light level above 7.

Behavior
Baumbas are ranged mobs that will follow targets both on land and in water. Like most ranged mobs, they will try quite hard to avoid getting into water, but will do so if necessary. When attacking a target, they will either stand still or slowly follow at a distance while firing projectiles.

They are aggressive, and will attack nearby players within 24 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.

Every 2.5 seconds, Baumbas will hop into the air. If they are chasing a target at the same time, they will launch towards the target while jumping.

Unique Abilities
When a Baumba's projectile hits a block or entity, it creates a moderately-sized explosion, damaging nearby creatures.

Hunter Mob
Baumbas are Hunter creatures that can only be damaged if the player is at level 78 or higher. When killed, they will grant 1145.8 Hunter xp.

Experience
Baumbas drop experience when killed.
