The World Balance is found in the Adamah Block of Tartarus guarding the 236th floor. In battle, it will actively attempt to target the weaknesses of the party members. It is also capable of detecting the Magic Mirror and Makarakarn skills (which would otherwise be excellent strategies for the fight).
The fight goes in three "stages". For the first third of its HP it will stick to elemental -dyne spells. For the following third it starts to switch to the Light/Dark skills, and when low on health it would try to hit a weakness before following up with Megidolaon. If a Magic Mirror or Makarakarn skill is used, the World Balance simply switches to casting Megidolaon every single turn. Some find that if they are able to heal enough to keep up with the damage from Megidolaon, its response to a Magic Mirror/Makarakarn would make the fight easier since the player would not need to face the Light/Dark skills.
Another viable strategy against the World Balance is to cast the spell Thunder Reign. This will shock the boss and leave it open to physical attacks and then a follow up All-Out Attack. However, the World Balance will switch to using Megidolaon every turn it gets after this is done. It is recommended to have a Persona with Mediarahan or a Persona with Mediarama and Divine Grace to offset the damage from Megidolaon.
After defeating this boss, the Judgment Social Link will reach level 6.
The World Balance is first encountered as a normal enemy on B5F and B6F of the Secret Laboratory. This variant will contsantly attempt to target the protagonist with Ziodyne spells. This will happen even if the protagonist nulls or reflects Electric attacks. If Yosuke Hanamura is in the party, he may occasionally be targeted. Collecting 6 Shining Dishes from the World Balance and selling them at Daidara will unlock the Fearful Kunai weapon for Yosuke.
The World Balance is faced again as a boss on Heaven's 7th floor. It has a far smaller skill set than its Persona 3 counterpart, having lost its Light, Dark, and Almighty spells. As a result, its tactics are far simpler; it tries to target the party's weaknesses to get extra turns, which it will use to either dizzy a downed party member, target another weakness, or cast Mind Charge to boost the power of its next attack. In addition, the boss variant follows a pattern of attacks, alternating Mind Charges with Agidyne, Bufudyne, Ziodyne, then Garudyne in that order.
In Golden, the normal enemy may also drop Buffalo Stone.
The World Balance appears in the 2nd Block of the Theater District. It attacks with heavy, single-target magic skills. When defeated, it may drop Balance Cache and Balance Halo. Balance Cache is used to create the Nihil for the P5 hero, the Labyrinth Sword for the P4 hero and Junpei, the Amakuni for the P3 hero, the Rappa for Yosuke and Koromaru, and the Full Jin-Baori male armor. Balance Halo is used to create the Hades Bow for Yukari.
