Bless you death arcanaImmediate answer: The deadlines are designed for a few ventures into palaces for the player to level up, but also keep the challenge at a reasonable level. If you feel the fight is too much, and you haven't let the deadline slip, there is no shame in bailing, cashing in the loot you win and gearing up. There is no wrong option with things like weapons or armor, just upgrade whatever you can. As for SP replenishment, sadly the only real options is lucking out if you hold up a Shadow and demand an item - they can drop SP heals - and buying certain vending machine drinks by school or the arcade. The downside of the former is they cover a measly 5 SP, and only 1 can can be bought per week.
Long-Term answer: Death is your friend. There is a reason you have access to that arcana early...
Also my first maxed out one hehe
