How To Navigate Tartatus
When you arrive in Tartarus, the group decides to split up to look for the key to the gymnasium. You’re given a choice of whom to bring with you –Yukari or Akihiko.
Itdoesn’t seem to matter who you pickto bring with you; just choose whichever of the two characters you like better.
After finding the gym key, head back to themain lobbyof the school to meet back up with the group, where you devise a plan to divide and conquer. Yukari and Mitsuru are staying behind, whileyou, Junpei, and Akihikohead into Tartarus to find Fuuka.
When you appear in Tartarus,the group has been split up. You find yourselfalone on an unmarked floorof the Arqa block.
You have a brief conversation with theMysterious Boy,who appears at the dorms to tell you about the Dark Hour, and then you’re free to run around Tartarus after speaking with him.
Communication is spotty, but your overall goal here is toreunite with Akihiko and Junpei. To do this, you’ll need towander through Tartarus alone.
Shadows are still milling about in Tartarusas normal, so be prepared to fight if you bump into any!
You hearanother voicecutting into Mitsuru’s broken communications as you go, eventually finding the staircase. There aretwo floorsto navigate alone before you locate Akihiko and Junpei on the third. Afterward, you’ll meet Fuuka before heading back downstairs to help your teammates.
Emperor And Empress Battle Strategy
Back at the entrance to Tartarus, not only are your teammates being attacked, butNatsukienters the Dark Hour, desperate to apologize to Fuuka after beingsummoned by the voice.
The boss shadows focus on Natsuki, and in a bid to protect her,Fuuka awakens to her Persona, and the battle begins.
As soon as the fight starts,ask Fuuka to evaluate the two shadows.She’ll reveal their weaknesses and affinities, which are exactly opposite one another.
When the fight starts:
This means thatmulti-target moves, while their affinities are like this,should be avoided.
We had the best luckfocusing on Empress first. The only magic she uses herself iswind,to whichJunpei is weak, so lay into her with physical moves and dispatch her quickly.
However, both shadows can cause aParadigm Shift, which switches their affinities around. If one of them uses it,their affinities are reversed.
Be aware of whether they’ve used the move, as the changes to their affinities can make or break your battle.
As we mentioned in the section where we listed their affinities, each time a Paradigm Shift occurs,have Fuuka scan Emperor and Empress. This battle ismeantto showcase her more advanced analytics skills, so make ample use of them.
Once you have their affinities and weaknesses pinned down, keep afloat with their changes and hammer on them with everything you’ve got.
The group leaves Tartarus following the Full Moon Bosses' defeat, and a few days later,Fuuka joins the SEES Team, taking up the role of yourcomms expertandfreeing Mitsuru up for use in battlethe next time you go to Tartarus after Fuuka settles in.
