Persona 3 Reload - Elizabeth fight in Merciless difficulty

Wow, having 100% P4G and P5R, P3R feels very easy to 100% in comparison.
I didn't follow a schedule guide (though I of course followed guides on what to respond during Social Links LOL) and was still able to play my way into a max Social Link first playthrough, and was surprised to find out they let you fight Elizabeth on first playthrough as well. I was completely expecting to have to do a second playthrough. Though them not letting you carry Personas and equipment over on Merciless difficulty made me force myself to essentially beat Elizabeth on my first playthrough (even though doing so is weirdly not required for 100% achievements, and neither is completing the Persona compendium for some reason)

Credits to    • Elizabeth Boss Fight (Persona 3 Reloa...   and    • The Orpheus only run got even better....   whose set-ups I was following religiously to beat Elizabeth with. I looked at all her rule set and just noped out of it lmao. I think Margaret fight in P4G is still the most enjoyable and yet challenging given that it's essentially a huge tank-and-spank with in-game mechanics that you have been interacting with your whole entire game, rather than you having to go out of your way to do weird shit like Elizabeth and Lavenza require you to

Here's what I did for Magic Mastery skill:
1. Wait for 3 days to full moon. When you enter Velvet Room, Elizabeth will inform you about it. Apparently you get better chances when you do so
2. Fuse 40 times for better chances
3. Choose only Personas from packs 3 (fool chariot moon judgment), 5 (empress hierophant hermit), and 6 (priestess fortune devil aeon) for 2.6 / 617.75 (0.42%) chance of a rank 8 skill mutating into Magic Mastery
4. Teach them four rank 8 skills (I went with Megidolaon, Vorpal Blade, Salvation, and Heat Riser since I have their skill cards lying around)
5. Inherit these skills and hope they mutate
6. Michael (Judgment) + Decarabia (Fool) = Ananta (Aeon)
7. Ananta (Aeon) + Dionysus (Moon) = Michael (Judgment)

Persona (Michael): imgur obbfGzK
1. Magic Mastery
2. Marakunda
3. Ice Boost
4. Ice Amp
5. Multi-Target Boost
6. Repel Strike
7. Auto Tarukaja
8. Mabufudyne (was using Auto Sukukaja but replaced it, will explain why later)

Equipment: imgur L1fQtpY
1. Lucifer's Blade (all stats +7 and Magic Ability)
2. Hallowed Plate (Enduring Soul)
3. Shoes of Light (Ali Dance)
4. Earrings of Grit (Endure)

Preparations for the fight:
1. Go to club and get fortune teller to buff the rate you charge your theurgy
2. Get protagonist's and Fuuka's theurgy charged before the fight
3. Get Auto-Concentrate on protagonist from Shuffle Time

During my first attempt, King and I on second turn was only doing 8274 damage, and combined with 1298 from God's Hand, was not enough to have Elizabeth drop below 10000 HP to skip her Diarahan while being vulnerable to Armageddon

During my second attempt, King and I did 8622 damage and God's Hand 1210, which still was not enough, so I replaced Auto Sukukaja with Mabufudyne to help deal some damage, since I figured Auto Sukukaja wasn't doing anything anyway

Then in my third attempt (as you can see in this video), King and I did 9145, but I've already wasted a Mabufudyne skill card so I swear to God of course I will freaking use it against Elizabeth LOL

Break down of the fight:
1. Marakunda
1: Inferno + Slash Attack
2. King and I
2: Rakunda + Concentrate
3. Oracle + Mabufudyne
3: Megidolaon (Enduring Soul) + Charge
4. Marakunda (she blocks ice this turn anyway)
4: God's Hand (Repel Strike) + Megidolaon (Endure)
5. ARMAGEDDON
