Monad Passages, Explained
The Monad Depths have all the time been a highlight of the unique Persona 3 story, but prior to Persona 3 Reload, getting there was no walk in the park. In some iterations of the sport, Monad was an end-game grind before facing Nyx, while in others, it was an optional challenge, but regardless, you used to must defeat The Reaper before going to Monad.
Persona 3 Reload modified this mechanic around – you do not must defeat The Reaper in P3R before you are allowed to go into the Monad Depths, which is a very good thing, since they begin appearing within the Yabbashah block of Tartarus while you first infiltrate, which will be as early as immediately after the July Full Moon operation.
But simply because you not have a troublesome litmus test ahead of venturing in doesn’t suggest Monad might be easy – the Monad Shadows are a few of the tougher fights in the sport, but as a reward in your bravery and training to beat these mini-bosses, you may be rewarded handsomely after every Monad battle in P3R with things like yen, costumes, weapons, and Major Arcana cards.
Monad Doors
If you first discover a Monad Door, Fuuka will highlight a large black door with a glowing red symbol that is positioned someplace on the ground. Run through that floor of Tartarus until you discover the door, at which point Fuuka will not let you permit the world without investigating this initial door.
Inside this door, you will find that Fuuka cannot navigate for you, but she warns that she’s feeling a fairly intense Shadow presence. Go further inside to seek out the Shadow she’s talking about, which puts up quite a fight to introduce you to the concept of Monad in P3R.
But, your fight is not for naught – defeating Shadows in Monad Doors offer a wealth of awesome rewards. Not only will you robotically have scanned the present floor of Tartarus and the one directly above it, but you should definitely check the two treasure chests just past where the mini-boss Shadow was.
There, you will find not only a daily reward like money or Skill Cards, but there may even be a Nihil treasure chest that glows green nearby as well. These chests offer Nihil items that will be traded in at over at Mayoido Antiques for powerful gear and armor.
Monad Doors respawn every night, all the time with a troublesome enemy and funky prizes, so it is often price it to enterprise in each time you are in Tartarus doing a little grinding or looking for Missing Individuals.
Monad Passages
Finally, after you’ve got gotten through the Monad doors in a block of Tartarus, you’ll need access to a Monad Passage that can spawn quite high up in the present block of Tartarus and remain on the ground where it spawns, even when you leave Tartarus for the night and are available back on one other day.
Fuuka remarks that these doors are different, they usually are – they react to Major Arcana cards you’ve got collected, they usually won’t unlock until you approach with the said card in your inventory. Major Arcana cards are most typically won while you defeat a Full Moon boss, but you will find that you furthermore may receive them as rewards from Monad Passages.
That is because inside, you are up against at the very least a couple of extremely tough fights inside Monad Passages, markedly tougher than another Shadows in the present block of Tartarus.
It helps to come to the Monad Passage with everyone’s Theurgy fully charged. Just be mindful to make use of any charged Theurgy attacks early in battle, since you may lose half your charged Theurgy gauge every time you are KOed in battle, rendering all work you probably did leading as much as the fight moot when you get KOed before you should use it.
Thankfully, Theurgy attacks ignore normal affinities, which is sweet, because the Monad mini-bosses often have affinity charts that make them fairly difficult to deal any meaningful damage to, so the more often you should use your Theurgy attacks in Monad fights, do it!
In the event you do not feel prepared or find that you simply’re not succeeding within the fight, you’ll be able to all the time decide to come back later when you’re under-leveled or not prepared yet while you discover the door. The advantage of Monad Passages is that the Passage stays on the identical floor of Tartarus while you leave.
Must you leave Tartarus and resume the expedition one other night, you may see the teleporter marked with the Monad Passage floor – it has a red Monad symbol beside the ground number. These will typically be right before the border floors, and there will be a teleporter nearby to supply easy accessibility should that you must leave and are available back.
Fuuka also double-checks before you trigger the fight that you simply’re able to take the mini-boss fight on, so you may never unintentionally stumble into these harder fights. You furthermore may have the choice to show around when you’re not quite ready.
Nonetheless, after you’ve got tested your mettle and proven victorious in these fights, you may receive a wealth of extremely worthwhile rewards, including but not limited to other Major Arcana cards for arcana not represented by the Full Moon Shadows.
There may be Twilight Fragment chests inside, along with a Nihil chest containing a prototype you need to bring to the owner of , so it is often best to return prepared, but you’ll be able to all the time double back for these rewards after the fight – Monad Shadows don’t respawn.
