Monsters & Bosses

Overview

Skeleton Warrior monster in Dungeon area

The monsters of MU are Kundun's servants, and defeating them is the heart of the game. They give experience and can drop Zen, weapons, armor, spell books, scrolls and parchments. Every kind has its own spawn places and its own drops, and each map holds stronger enemies than the one before, guarded by level limits. Golden versions appear during Invasions.
