Will Chaldea Lunchtime end before Christmas event?

Assuming you're at a decent amount already, ~2k or so, you'll have plenty of time. I believe we have close to 90 days, if not actually 90 days, to gather all the MP we need. Refrain from getting anything other than summon tix during the monthly MP store and you should be good. If you're starving for MP, like, you have ZERO (WHICH YOU SHOULDN'T CUZ THIS EVENT GAVE A GOOD AMOUNT), then I suggest you get on it and start grinding the bloody heck out of the 30 AP daily Ember Gathering quest and selling every silver exp card you nab. Also burn 3 star servants (assuming you don't want them) and 3 star CEs (assuming you don't want them).

Here's a link to what you should be able to expect as far as Mana Prisms are concerned. Figure out where you are so you can budget your MP usage/acquisition.

Same issue guys. I have around 1k1 MP right now, expect to have about 1k5 after this event. Should i start to grind right after prisma? Will it be enough if i spare some for the monthly tickets?
