Maeiga

Eigaon
This is Demented Knight’s ultimate move. It does massive Dark damage to a single target.
The floor guardian Demented Knight comes as a boss duo this time around, but both of the enemies in this boss fight finally have the same affinities. The two Demented Knights have an interesting skill set that is centered around chipping away at your entire party’s healthusing two different area-of-effect skills, Mazionga and Maeiga.

Both of the Demented Knights are weak to Wind, while both nullify Pierce and Fire damage.
They both know Matarukaja and will open with it to boost their attack, only using it again if the buff falls off; once the two have delivered a few attacks, they will use Concentrate followed by Eigaon. This combination of skillsis sure to kill its target if you do not debuff the boss.
Demented Knight Battle Guide
The floor guardians offloor 161of Tartarus come as a pair of Demented Knights ready to hold your team hostage, not allowing you to progress without first defeating them. The recommended level for this boss isnear level 52.
The Demented Knights are both weak to Wind, which makes Yukari an attractive option for this fight, but sadly she is weak to Electric damage - something the Demented Knights will use almost every other turn.
With that said, if you choose to take her, make sure to equip some kind of Electric resistance gear; this guide will be leaving Yukari out of this fight.
The bosses nullify Piercing and Fire damage, so Junpei is out of the running. Ken and Aigis will also have to stay behind as both bosses use a mixture of Electric and Dark attacks.
This leaves our team withKoromaru, Akihiko, and Mitsuru, andthe Protagonist will need to fill the shoes of the Wind skill user here.As these two enemies have the chance to inflict shock on your team, bring along a stock ofBaisudi Gems, Maibaisudi Gems, Amrita Gems, or Amrita Sodas.
Mitsuru Will Try To Freeze The Duo
Mitsuru hasneutral affinity interactionswith the two Demented Knights, both offensively and defensively. This means Mitsuru’s only priority is to do as much damage as possiblewhile trying to inflict Freeze since her Persona has Freeze Boost.
Have Mitsuru cast Mabufula every time it is her turn. If only one of the Demented Knights is alive, cast Bufudyne instead.
Koromaru Nullifies Dark Damage
You should bring Koromaru along because heignores damage from two of the three attacking skillsthat the Demented Knights use; this includes their ultimate ability Eigaon.
Koromaru’s first turn should be spent usingRevolutionfor Akihiko’s attacks. His proceedingturns are best spent using Virus Breathas it does slightly more damage than Maeiga.
Akihiko WIll Use Strikes And Debuffs
Both of the bosses will try to have Matarukaja up as much as possible, so it is imperative to useDekaja or Matarunda. Luckily for the team,Akihiko has Matarunda.
Akihiko will alsonullify all Electric damage;unfortunately, both of these enemies are immune to being shocked, so he gains nothing from his Persona’s Shock Boost. Instead, you should capitalize on Koromaru’s Revolution by using Gigantic Fist to attempt critical strikes.
On Akihiko’s turn, you will want to use Matarunda as a priority if either of the two following conditions has been met
Otherwise, have Akihiko use Gigantic Fist on his turns. If any team member needs healing, use his Diarama on them instead.
Best Persona For The Protagonist
The Protagonist will have to fill in for Yukari here.Choose a strong Wind skill Personato guarantee an opportunity for your team to All-Out attack each round.
Here is a list of some of the best options at this level for the Protagonist’s Persona:
How To Fuse A Persona Immune To Demented Knight
If you want toguarantee victoryagainst this boss, you’re able to create a Persona via fusing that isunable to take damage from both Electric and Dark attacks. Doing this is very expensive, so only proceed if you have extra money.
To fuse the Persona, follow these steps:
This fusion will result in the Devil Arcana Persona, Succubus. It will nullify Electric damage, absorb Dark damage, and have access to Magarula.
If you proceed with this fusion, you do not have any need for the rest of your team as you can justuse Magarula every turn for a free All-Out attack and you will never get hit by the boss.
