This is a lot more complicated compared with other past events I've been in for me.
I just want to clear the events item shop of mats, xp/stat cards, pieces/monuments and mana prism. I probably would skip the CE's if it doesn't really help in farming for more.
I'm busy this week so I can't play much, yet I badly needed those mats to max asc Vlad and my other 4* servants.
What to do? I've looked at the events page here and it's a mess to me.
Thanks!
Don't let the complication scare you, if you're not interested in the gift CEs then you can just maximize your drop bonus for a specific enemy class and use those molds on the appropriate farming nodes. Every chocolate coin translates directly to the Baking Chocolates you turn in at the shop if you don't want the CEs.
If all you're going for are the mats then there are a few things to keep in mind since the whole thing is a bit complicated:
1. The Give/Receive chocolate CE's pretty much just collector's items and the choco bonuses are restrictive. No need to get them if you're just focusing on mats.
2. In accordance with above, choco coins are useless by themselves, turn them into baking chocolate in the shop which you can trade in for mats, 1coin is to 1 baking choco.
3. Try focusing on 1 class-chocolate to farm. If you can get a team to easily farm 1 class, freely use the Chocolate Mold(Molds turns all the enemies in the quest into one class) items for that specific class. The droprate on the highest difficulty is also pretty good so you'll always have a choco mold to use.
4. As for CE's:
Buy the Fondant au Chocolat and Sweet Crystals from the shop. They give +2 to choco coins for all classes, so no need to mix and match classes. I maxed one out(+3) and the other I used individuals(+2x4) so that's +11 for all choco coins. They're pretty nice CE's by themselves too.
Get a support with one of those +5 or more bonus CE's. You need to get the appropriate bonus for the class you're trying to farm, so you need to check that.
You can get around 250-300 baking chocolate for the highest difficulty free quest.
Hope that cleared up a few things.
Just a few more tips: presuming that you use a mold to force a single class of opponent (which I also fully recommend, not just from a drop viewpoint but also lets you concentrate on using class advantage to the utmost), then try to maximize the class drop bonus as almost all of the drops will be of that single class (FYI, I don't use Berserkers or the extra classes, and am not sure if that affects the types of drops...). Until recently, I found a friend with a +5-6 bonus against their weak class (e.g. using their archer when I use a saber mold). I happened to have a Bitter Chocolate CE (+3 to weak class), and I got 4 Fondants. This gives me a bonus of +16 for the selected class, and +8 for others. I just pulled a Cute Orangette, which I replace one of the Fondants with, to give me a bonus of +19 for the class and +6 for others. Using this, I will get around 360 chocolates per run of the Royal difficulty. I can run that 7/day, and there's around 9 days left, and with what I've already farmed, I estimate having around 29,000 to spend.
I then go to the Event Shop Planner, and adjust the numbers such that I can plan on what that buys.
Since it's all very bonus-dependent, you'll need to do your own math. The Royal difficulty for me has been dropping an average of 31 class coins in 13 stacks, 9 "all" coins in 3 stacks, and 59 chocolates (stacks are irrelevant as there's no bonus). So your math is:
31 + 13*class_bonus + 9 + 3*all_bonus + 59
My recommendation is to buy more of the Fondants rather than the Sweet Crystal, as MLBing the Fondants is more impactful (you get a divine damage bonus in addition to the NP charge, while Crystals only give you the NP charge extra since the pierce invulnerability effect does not get a bonus from MLB). I'll still probably pick up a Crystal or two, but might not MLB it eventually.
In my opinion, the best classes to farm are Saber or Lancer, and Caster. This is because Archer and Assassin have short charge bars to contend with (primarily in the first wave, because hopefully you can NP the 2nd and 3rd waves in a turn or two). I also prefer Caster over Rider as Casters don't hit back as hard, which is particulary of interest as they would be advantaged over your own Caster supports :) I also don't use Berserkers because 1) you don't need to given you can use class advantage (and remember that Berserkers only get 1.5x damage as opposed to 2x with a class-advantaged servant; and 2) with class advantage, all but your support are taking half-damage, so even on Royal difficulty you can just about ignore defense except for enemy NPs--with a Berserker, you'd probably need defensive support, and this slows you down for farming, if you care about that.
