I need help, I have to do the mission of meko to get ectoplasm but I accidentally spent the torches before, does anyone know where I can get more torches? (I'm on the nauxus route)

Did you finish the war with the Bull tribe? Then I'm very afraid that you can't buy anymore torches but!! There is a point in the night and day that you won't need torches to enter in the dungeon sometimes so just visit the dungeon every now and then.
