Club / Doujin Circles
- A total of 5 Clubs (plus one) will be participating in the Servant Summer Festival!
- Masters can obtain limited time Craft Essences with special art, each themed towards the club's interests from completing Club Quests.
- In order to progress through Club Quests, Masters must complete Delivery Quests for each Club! There are a total of 9 possible deliveries made to each of the clubs, which use Event Food instead of AP.
- Completing deliveries will level up the associated Club, improving the buffs they provide.
- Completing deliveries also awards an ascension material depending on the Club.
- A full list of all delivery quests and their costs are here.
- Club Levels increase the potency of buffs provided by the Event Craft Essence:
Event Bonus Servants
Event Bonus CEs
Should I Use Apples?
Is there a place to ask questions?
Small thing but I believe step 82 is unlocked after step 84

Thanks, swapped the ordering! Should update in a few minutes.
yeh
On 152, the NP is Single Target not AOE

Thanks, fixed! Should reflect in a few minutes.
#172: Upon the defeat of the frontmost servant, the one right behind them gets taken over. After that, the backmost servant is sacrificed, leaving the middle servant to be the one who needs to be taken down.
When I knocked out all three at once on turn one, only the middle one came back, so it had the damage reduction or whatever for a turn, but I didn’t have to take out all three separately.

196 appears to be a choice. The 2nd option makes you fight an avenger (277k HP) and assassin (236k HP). The avenger has unremovable quick crit rate up, the assassin has an unremovable 6 times evade.

Thanks a ton! Updated the walkthrough, it should show the fixes in a few minutes.

I also got 1 stack of Primal Energy Drink (x3) and 1 stack of Emotional Steak (x3) from this
Would you guys consider adding a total read time for at the beginning or end of these walkthroughs? It'd be nice to gauge how long the story is so I can decide to skip the story to speedrun the event (I'm late -_- ) and read later or if I could afford to read through the event normally.
I did step 71-74 (bishonen) before 65 (Ch4-3) and now I lost it. Anyone has a yt video of that? I've only found the one with Oberon, but that is 4-2.3.

I'm not sure what you mean by losing it. Is 4-3 not visible at all in your game? Did you buy the popsicle from the shop for 4-2.3?

179 it should be a Rider instead of a Berserker (HP and drops are correct)

Thanks, fixed! Should update on the page shortly.
For step 142, it says that 50 Primal Energy Drinks and Emotional Steaks are required, but it seems like 55 are needed instead.

Oh weird, are the costs for the Faerie Britain Chaldea quests wrong? For Energy Drink / Steak, for the first five errands I get 5 + 8 + 10 + 12 + 15 = 50 total, did I get one of the costs incorrect?
think 185 and 186 should be swapped since the story quest comes before the delivery quest.

You're right, thanks! Updated, should reflect on the page in a few minutes.
