1) Clear the waves of minions using spells they are weak against
Your main target isn’t really Mammon, but his lackeys instead. The first wave is weak to fire and wind. Having Hell Biker armed with Maragi is very helpful. The next set is purely wind skills, so having Morgana or a persona with wind skills is a good idea. The next set is a test of Psy and Agi skills. If you have Haru Okumura, have her cast psy attacks. After that, attack the two blue lackeys in the middle with fire attacks.
The next set has three golden lackeys and one lanky, tall one. The tall lanky one is weak to nuclear attacks, making Makoto a good choice. The last three can be taken out with Haru’s Psy skills. Next, you have four tall and lanky lackeys, three red and one blue. The red lackeys are weak to nuke and electricity, while the blue are weak to wind. Next set has two large green lackeys and two blue lanky ones. The two large green lackeys can be shoved off with psy attacks and two blue lanky lackeys lose out against wind skills.
2) Look after your HP and cast debuffs
After he sends the waves at you, Kunikazu Okumura sends Execurobo MDL-ED, a massive black robot that dons a formal suit. It doesn’t have any weaknesses, so just attack how you want. If you have debuff spells, they could help speed up the fight. Spells like Rakunda and Matarukaja will definitely help in defeating the boss. However, do watch out for its Charge spell. It can hit you hard if you’re not careful. Also, having Hunger will save you from its Big Bang Challenge attack.
Once you defeat the large black shadow, you finally get to put down Kunikazu Okumura. He’s not that hard, so keep whittling him down to finish the palace.
