An elder guardian is a aquatic boss mob and a stronger and larger variant of the guardian, and it can inflict Mining Fatigue. It is the largest aquatic mob in Minecraft currently. Three of them spawn inside an ocean monument; one in the penthouse room and one in each wing.

First of all, I fixed the original size of the Elder Guardian, which is actually 4x bigger than a common guardian.

Level: Easy-Medium

Soon with more projects, folks
