I can't find the mob that drop Eternal Torch for All-nighter quest! Anybody know where i can find it?
please help me thank you ^^

The boss in Well of the Five Virtues,the drop is pretty rare.

You can get it from Wanyuudou which is the boss of Cave of Nakisawame. I think other Nyuudou drop it as well but I haven't seen any from my Nishidera runs, and Cave of Nakisawame is the lowest level dungeon where Nyuudou spawn anyway.
