Unlike Monad Doors, Monad Passages inPersona 3 Reloadfeature a series of bosses that you’ll need to defeat to reap the rewards. They’re much tougher than their Monad Door counterparts, but unlike Monad Doors, Monad Passages won’t disappear if you leave the floor. They’re also set a floor below the Border Floor.
You must defeat a Shadow called the Amorous Snake in one ofPersona 3 Reload’s Monad Passages. Fortunately, the Amorous Snake has an Affinity weakness, but if you try to battle it unprepared, you’ll be in for a difficult fight. It’s recommended to bring teammates who can target its Affinity Weakness, heal/cure, and buff/debuff.

Where to Find Amorous Snake in Persona 3 Reload
The Amorous Snake is the first boss in theMonad Passage on the Harabah Block (floor 197). If youdon’t have the Star Tarot Cardfrom the Monad Passage on thesecond half of the Tziah Block (145 - 172), then you won’t be able to enter Harabah Block’s Monad Passage. Thus, you’ll want to reach the end of the Monad Passage on Floor 171 andget the Star Tarot Card from the chest.

Which Party Members and Personas Should You Bring?
Before diving into Floor 197’s Monad Passage, there are some things you’ll need to know:
How to Beat Amorous Snake & Devious Maya
Amorous Snake Weakness
The Amorous Snake will use its turn toCharm or Poison. you may cure Poison for all allies with theMabaisudi Skill; Charm can be cured for all allies withMe Patra. If you don’t have Personas or a teammate with these Skills, you can instead useDis-PoisonandDis-Charmitems, which can be bought from theAohige Pharmacy at Paulownia Mall.
If you bring Yukari to the fight, she can cure Poison withMe Patra, which she learnsat level 33. If you’ve Fused the Personas Sarasvati or Pavarti, they will both have Mabaisudi in their initial Skill Set.

The Amorous Snake isweak to Ice and absorbs Fire and Light. This means you can use Mitsuru’s Bufu Skills to Down it. If you’re trying to complete the Harabah Blockas soon as it unlocks,Mitsuru won’t be available. If this happens, you’ll want to bring a Persona that can use Bufula or Bufudyne.
The Devious Mayas will castTetrakarn and Makarakarnto reflect incoming Physical and Magical Skills (excluding Almighty) respectively. The only way to rid Tetrakarn/Makarakarn of an enemy is to attack it with physical or magic skills. Unfortunately, this will cause the attack to reflect right back at you, so if you plan on attacking a Makarakarn-guarded enemy, verify to use an element that you will resist, null, drain, etc.

The best way to take out the Devious Mayas is with Physical Skills thatcan hitall foes. This is generally why Aigis is preferred over Akihiko for this battle, as she has Skills such as Heat Wave and Myriad Arrows. Another alternative to defeating the Devious Mayas is to useAlmighty Skills, such as Megidola or Megidolaon. Even Koromaru’sVirus BreathSkill can come in handy for this battle.
For buffing: Use Matarukaja (to raise Attack), Marakukaja (to raise Defense), or Masukukaja (to raise Accuracy/Evasion). Aigis will have access to Matarukaja and Marakukaja, and Akihiko has Masukukaja.

Another tip is touse Theurgies. If you need to, go back to the lower floors andmax out everyone’s Theurgy Gauge. Then, enter the Monad Passage and start the fight. With Theurgy, you should target the Amorous Snake first.If you have the protagonist’s Theurgy, useJack Brothersto potentially Down all opponents, then follow up with an All-Out Attack (or heal, if needed).
Finally, before confronting the Amorous Snake, you can useFuuka’s Sylphid Aura Skill. This will raise the party’sDefense/Accuracyfor three turns at the start of battle. Be warned that Sylphid Aura’s effects only last forone battle.
