Momentus

Momentus is a giant zombie which is one of the EMC bosses that spawn every other hour. He is known for getting less damage from arrows and it's recomended to use melee combat when facing him. He spawns Enraged Guardians and also pulls in his victums.

When Momentus is near a player a message in the chat would say, "The ground shakes nearby" to warn the player that he's near.
