Krenaht:
You have slayed all of the Mimillions. I'm afraid there's some bad news, though.
Emperor Helios has issued his orders, and Mimir has returned, stronger than ever. Unless the Enhanced Mimir is defeated, our safety cannot be guaranteed.
Please slay the Enhanced Mimir.
Also, after the Enhanced Mimir reveals himself, they say that the Superion Scouts might appear as well.
You must not let the Superion Scouts Delta Bathus, Delta Carcass, and Delta Kshana roam about freely in the Giant's Cave. Take out 200 each of the Delta Bathus, Delta Carcass, and Delta Kshana.
