gudaguda rerun

I haven't done Gudaguda myself because I only start playing in late May, but when I was doing The Great Tale of Demons Onigashima to get Kintori, I don't remember I need to burn lots of apples, and easily finished it. From memory I only use 5-6 apples to give a little push, but other then that, I finished on time. I guess as long as you max your AP usage (basically keep the recharge clock ticking) you should be ok. Unless there is a specific node you wanted to farm for materials or you wanted to clear the shop.

I'd say it's unecessary. Just make sure you always field all the servants that give point bonuses with the event CEs and borrow a support Okita. There are limited quests that can only be run once each day that gives a lot of points so check if you have all possible bonuses equipped before you run the mission.

You also get a couple of fruits as you go up the point ladder. Make sure you get the skull ascenscion materials from the shop as well.

To max her out ASAP, start saving gold archer exp and buy her ascensions mats (I’d get event ce too) as soon as you can.

To max her NP you need to hit 1M. The daily quests should cover about 3/4 of that without your own Okita. So you probably won’t need apples.
