Insane Damage in Persona 4 Golden

Using a precise setup against Golden Hands in Magatsu Inaba, we get quite possibly the highest damage in the entire game.

PRE-SETUP: Kanji needs his final Persona, with Vile Assault, Power Charge, and The Man's Way (The Man's Way is optional, but it makes this significantly easier). Kanji must also have 99 Strength, and he needs his ultimate weapon, the Perun Plate.

Hero needs to have Debilitate, or you need somebody with Rakunda/Marakunda to lower the enemy's defense. You also either need Heat Riser, Tarukaja, Matarukaja, or Auto-Mataru to increase Kanji's attack.

The difficulty should be Easy or Very Easy (you need extra damage from the difficulty settings).

THE TARGET: The enemies that take the most damage from one hit in the entire game are Golden Hands within Magatsu Inaba. So, you need to find one out in the wild to get Player Advantage.

THE BATTLE: First, you must set the stats in place. Have somebody lower the Golden Hand's defense, have somebody else boost Kanji's damage, and have him Power Charge. Then, use The Man's Way if you have it, hoping to cause one Hand to become dizzy. If its defense is not already lowered, lower it on the next turn. Make sure you have Kanji's attack increased, the target's defense lowered, that Kanji has a Power Charge ready, and that the target is Down or Dizzy. Then, use Vile Assault.

This method results in the highest possible damage within my testing.
