While you were training, I uncovered Astaroth's whereabouts. But you can't get to that place because of an extremely potent and pungent smell. I began to think of all the alternatives there is for you to get through, and I finally found an answer in the ancient book. You may not be too thrilled about it, but would you like to at least hear what I have to say?

No matter how potent the smell, it wouldn't matter if you didn't breathe it. All you have to do is equip yourself with a device that would prevent the stink from stimulating your sense. I just need a few items to build you one. Would you bring me those items?

30 pieces of Wild Boar Leather, 30 Evil Eye Eyeball, 30 Charm of the Undead.

You must be scared!

Wow, I know it wasn't easy. Let me see what you've brought. Good! Everything I needed. Now, just give me a few seconds and I'll make you an awesome Gas Mask.

Phew, it's finally finished! It was hard to make because the Ancient Book contained only vague instructions. Look, what do you think? This is your Wild Eye's Gas Mask! If you put this on, you'll be able to pass through without inhaling any poisonous gases!

I need 30 pieces of Wild Boar Leather, 30 Evil Eye Eyeballs, and 30 Charms of the Undead.
