Phantom of Madness Quest – Shin Megami Tensei IV
Where to find the horde of demons after accepting the Phantom of Madness quest
They appear at random locations in Shinjuku, however, I encountered my first horde at the East Entrance Main Street of Shinjuku. After defeating the first horde of demons, the mapper app will pick up the locations of the reminding hordes, making it easier to complete the quest.
I found the last horde and Chernobog at ‘Shinjuku – Golden Gai’. Take note, after a certain time period, the pink symbol that represents the enemy in the game will disappear and reappear at a different location of Shinjuku. The horde of demons don’t go too far and they’re really easy to find. They’re all at Shinjuku, you know.
What is Chernobog’s weakness and how to beat him

As I mentioned earlier, Chernobog is the last demon to fight for the quest after defeating the last horde of demons. He appears as reinforcements, therefore, it is recommended not to give the horde of demons a chance to lower your team’s HP.
What is the horde of demons’ weakness? – The horde of demons consist of zombies, and zombies are weak against fire element attacks. My entire party knew at least one fire element skill, so it was easy to defeat all of the demon hordes that appeared for the quest.
Getting down to business. I have failed at finding Chernobog’s weakness. I tried almost every attack element in the game and yet Chernobog stood strong. I assume you will lose a turn if you use a dark element skill because of his nature. However, that’s only a guess.
Be careful when battling Chernobog. He knows a physical attack that hits all enemies that has the possibility of inflicting the poison status. I managed to defeat him by using demons with around 300 to 400 HP, while using skills that greatly healed my team (eg. Mediarama).
