The Diamond Golem is a boss and a minion of the Dark Emperor in the Find Mii 2 secret quest, where it can be seen guarding the princess, thus making it one of the guardians. It resembles the Iron Golem, but it is made of diamond. Like other golems, it is immune to level 1 and 2 sword attacks. Ironically, despite it basically being a stronger version of the Iron Golem, the Diamond Golem is actually vulnerable to black magic, whereas the Iron Golem is immune, even though it is weaker. When it is defeated, it collapses and vanishes into purple smoke. It has 85 HP and uses Fortifiyng Magic.
