The second and last major road block that requires a large amount of EXP grinding.

Let's have a quick recap on why this boss is so difficult to deal with, it has 3,200 HP, Magic Mirror or Makarakarn triggers Megidolaon spam and if fought normally it is divided into three phases:
Above 50% HP: Not too bad, MC can potentially get through this phase alone with a Null Element Persona. Uses Ma-dyne spells randomly, occasionally uses Megidola. Uses One More with with Spirit Drain if the target has large quantities of MP else random offensive spells excluding Megidolaon.
Below 50% HP and above 20% HP: Uses Instant Death spells with increased frequency of Almighty usage including Megidolaon. Uses One More the same way as Phase 1.
In this phase, MC will have a high chance of getting wiped from Megidola that does over 500 damage or Megidolaon that does over 700 damage without buff/debuff due to the World Balance's increased usage of Almighty.
Below 20% HP: Tries to exploit an elemental weakness for One More based on the order that elements are listed in the affinity table(Fire, Ice, Elec, and Wind), if no elemental weakness can be exploited then spams Megidolaon. Use One More with random offensive spell including Almighty though seems to favor Ma-dyne spells more, however if a target has Repel for the element it is going to use then there is a very high chance that it will use Almighty.

Despite its high damage potentially, unlike the Sleeping Table, MC only needs to reach Level 53, with only an additional 15,988 EXP needed. At Level 53 Thor now can be fused. With Thor, the Fusion spell Thunder Call is unlocked. This fusion spell is sort like a less powerful version of Thunder Reign that can target multiple enemies and with a 100% Shock chance.

Get a turn order where Akihiko goes before the Balance, this required because in order to achieve Stun-lock, Akihiko needs to use physical knock down the Balance. Use Thunder Call on MC's turn, and set Akihiko on Heal/Support, use Rush to force Akihiko to attack with his equipped weapon, cancel Rush and relent AoA. Akihiko will automatically use a debuff skill on the Balance with his One More as long as the Balance is not fully debuffed, if the Balance is fully debuffed switch Akihiko's Tactic to Knock Down to prevent him from hitting the enemy again. Repeat the process until the MC does not have enough SP to cast Thunder Call, switch to Daisoujou to recover SP, the Balance should be below half HP and starts using Instant-Kill skills and Almighty skills, whichever it uses does not matter since with Enudre skill(morphed from any morph-able Rank 5 skills, such as the single target -Dyne spells)on Daisoujou and Akihiko with the Spirit Brace(can be obtained from the Retrieve 2 Red Armor Plates Request or farm Heart Item from Titan) will endure one fatal attack. Once MC's SP is fully recovered resume the Thunder Call strategy until the Balance goes down.

Rules:
Only MC and one other party member are allowed to act in combat.
Minimize EXP Gain whenever possible by doing only mandatory battles.
Due to how level scaling works in Persona 3 FES and this being a Hard Mode run, EXP grinding might be unavoidable in certain situations.
When EXP grinding is required, MC's level cannot be higher than the level of the next guardian in line or the Full Moon Bosses, whichever level is lower.
Will attempt all Elizabeth's Requests for a New Game Cycle, other than Fusion Spell requires high level Personas and Request #53.
