Goalby

Goalbies are hostile melee mobs that spawn naturally in the Overworld.

Spawning
Goalbies spawn naturally in mountain-type biomes in the Overworld.

They will only spawn during the day, and like most other mobs; their spawning can be prevented by placing torches or other lighting blocks nearby to raise the light level above 7.

Behavior
Goalbies 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 Goalby successfully attacks an entity, it will apply slowness 1 for 2.25 seconds.

Experience
Goalbies drop experience when killed.

Bestiary Entry
"Surprisingly lightweight creatures, Goalbies are actually a species from the Haven dimension. They originally came to the overworld during the last great dimension clash, in which several species from a number of dimensions were leaked across their borders. Their large wing-like appendages exude tiny spores that are easily dislodged. When they come in contact, these spores cause temporary muscle weakness and fatigue to most living species.

Like most Haven creatures, Goalbies are aggressive, and will attempt to attack even when unprovoked."
