L77. Battlefield Disaster 4

"Adventurer, to annihilate the Dark Lord, we must make a treasure called a Demon Shirt. It's not something you can get at the Gap."

"You must collect the materials required to make it from the Horror Demons and Soul-Devouring Demons in the West Branch of the Polar Palace."

"You need Demon Skin and Demon Horn. A skilled adventurer like you shouldn't have a problem with this quest."

"When you put on the Demon Shirt, you will appear as a demon. When you fight with Vani, it will seem like a fight between demons, so the Claws and Fangs will not attack you."

"If you have all the materials you need, you can start making it now."

Nice work. When you complete the Demon Shirt, you can begin the great battle.
