Help me MLB Halloween Princess

Why so desperate? Stop spending any more apples and save them for Christmas 2018 lottery. You get a better version of Halloween Princess there and better use of your apples as you are using them for the lottery anyway

Person above me is right that it's wiser to save apples for the lottery on the Christmas event, as well as a similar CE with better stats, but I understand the want and need too for wanting to MLB this CE. To answer your last question at least, Jeanne's the one who you should defeat first since she's the one who drops it.

no point wasting apple just for one CE, there are tonnes of other good CEs in this game that you will probably be able to use. Apples shd only be used for Lottery. Rather than farming for the CE, in fact this event is perfect to replenish apples used in Nerofest.

My friend just believe in yourself. I just got it with 3 apples. You can do it

Got a Maid from Visitor in Rain. Got a Princess from the Emiya party quest. Just keep doing those quests first before grinding the free quests. Else, get acquainted with Vlad and the kitty.

if your lunatic party still there you can kill atalante then out if ce not dropped
