Short version: This is the first time ever playing through P4. I've been loosely following the PS2 P4 strategy guide for the game.
I'm in Yukiko's castle, and on the last day before she bites the dust (the 29th). In the guide, it says to go three times to the castle: the first day you can, the 27th, and the 29th because of social links. So I did.
I'm trying to fight Shadow Yukiko. Getting killed. My characters are all level 11. The guide says I should grind, which is somewhat confusing because I only have one day before auto game Over, which means I can't go out and just buy tons of items to help keep my SP and HP up. What should I do? Walk around the lower levels for awhile and keep hoping I get the cards that restore my SP and HP?
The guide also says I need to have all these Personas at much higher levels than I have them so I can fuse into one that makes the boss fight a cake.
I hope I've not screwed myself over. I might just not understand the game fully yet.
Also, I accidentally fused Izunaga. The compendium can help me get him back, right?
