Quick Answer

Do not spend many small days inside a Palace if you can avoid it. Prepare recovery, SP support, and useful Personas, then push to meaningful checkpoints in fewer visits. Send the calling card after you secure the treasure route and can fit the boss day around the calendar.

Pre-Palace Checklist

CheckWhy it matters
Healing and SP supportReduces forced retreats
Useful elemental coverageMore weaknesses mean more turns
Lockpick preparationPrevents missed chest value
Confidant and stat obligationsAvoids losing key calendar days

When To Keep Pushing

SituationRecommendation
SP and party health are stablePush to the next safe room
You reached a puzzle with resources leftSolve it and secure the new checkpoint
Enemy pressure is manageableContinue instead of exiting from normal attrition
You are close to the treasure routePrioritize finishing the route setup

When To Leave

SituationRecommendation
SP is nearly empty and recovery is goneLeave before a bad fight snowballs
Key party members are down and items are thinRetreat and protect the route
A safe room is open but the next stretch is unknownBank the checkpoint
Tomorrow has an important Confidant or exam planCompare the calendar cost first

Calling Card Timing

Once the treasure route is secured, check the next few dates. If there is no major Maruki, exam, story, or key Confidant conflict, send the calling card soon and remove Palace pressure from the calendar.

The goal for a normal first run is not a perfect one-day clear. It is to avoid unnecessary repeat visits so Confidants and social stats have room to progress.

Common Mistakes

Waiting until the final three daysSchedule exploration as soon as the deadline opens
Leaving before a meaningful checkpointPush at least to a safe room when possible
