So what do you farm after finishing the 5th chapter ?

After clean all freequest from america, exp cards

Focus on clearing any unfinished Free Quests and Interludes, afterwards I'd recommend focusing on farming either EXP cards or QP. The drop rates for most ascension materials aren't very good so it's usually better to leave farming them for events where they drop at much better rates.

If you really need a specific ascension material and can't wait for an event to farm for it, I'd recommend consulting this spreadsheet to find the best spot to farm.

Dont bother farming gears...or claws....or talons...or pages...or feathers. You will get at least 20 of each, and more, with the upcoming davinci and the 7 heroic spirits event.

1. Do all of the free quests

2. Grind Qp. You may be sitting on at least 10mil now, but thats not enough, always more QP.

3. Grind Dragons reverse scales and Hearts. Dragons reverse scales because its a valuable and hard to get resource(and you also dont get it from davinci) and hearts. You need hearts on pretty much any high level skill up in the game, and many servants need them in their ascensions. I'm sitting on around 60 hearts, but hats nowhere close to enough for me.

3. Try grinding embers in the dailies and leveling up some 1-3*, but its not very high priority since you get a metric buttload of them from davinci events
