You can hunt it from Beelzebub, he has to be his 2nd form to drop any loot btw. You can summon him through Enchanted Branches, Bloody Branches, Houses, and you can search for a fly form at abbey03. To get him to his 2nd form, you have to take around 50% of his HP, and there will be a bar slowly filling up. Then he'll be his 2nd form and you will be free to kill him.
Use Ghost and 4 gloom undernight cards cause they do beast damage to it o:
