Inventor Maru:
Thank you so much! That will be very helpful! Let me tell you about the materials I need.
They are called "Energy Ore".
Fortunately, you can easily acquire them by hunting the monsters in the Eastern Mining Zone to the north of the Dwarven Village.
Let's see, the monsters there are mostly "Red Eye Barbed Bats, Northern Trimden, Kerop Werewolves, Kerop Werewolf Chiefs, Northern Goblins, Northern Goblin Leaders, Spine Golems and Enchanted Spine Golems." Those are the monsters you'll have to face. Understand?
Now, please gather as many Energy Ore as possible. Ah! I am far too busy! Too busy! I need to hurry up and review the blueprint. Good luck!
