After reaching the level of 1 10, players can receive the "Magic Fire Test" task from Vanessa Cyrus in Dalaran's magic store. In the task, he mentioned "dust control", a substance produced by high heat, and then he asked to make four kinds of wristbands.

If it is not a manufacturer, please prepare a lot of G or trade with people/friends in the guild. Ah, you can buy it, it's not so expensive now, and then you're ready to hand in the task ~

Then he put the wristband I had worked so hard to get into his makeshift furnace and made two "dusters" (spit it out for me, you fragile soul). The result of calcination is not satisfactory. We need a stronger furnace. If we want to build this melting pot, we need to get the consent of the Sixth Law Conference.

After I came to Violet Castle and asked Khadga first, Khadga instructed me to ask Carlin, the exorcist. Karen said he knew someone who could help us build a stronger furnace.

This man named Osana Motu refused to join Dalaran's system, preferring to stay in the sewer.

I found Osana in the sewer. It was actually a demon hunter, and her tone was very arrogant.

Osana said she could help us build the furnace, but she needs us to help her get some necessities first.

The first is the materials needed to build the furnace: heat insulation cloth, heater and alchemy flame. Then he needs some adhesive, of course, not ordinary adhesive. Only the longest-lived creatures in Dalaran sewer can reproduce. Finally, there is a little reward. Fortunately, he is not interested in gold coins, but he is very eager to be blind. Everything is ready, hand in the task! O 'Shana said that Karen had found a suitable place on the ground to build the furnace.

Back on the ground, the furnace has been built and is waiting for acceptance.
