Your goal in the first Palace is to secure the infiltration route early, then schedule the Calling Card and boss day. Do not spread Palace progress across too many free days if you can avoid it.

Common Problems
Problem
Adjustment
SP runs out
Use weaknesses, guns, items, and fewer wasteful casts

Secure the route before the final days
