Thank you for the prompt walkthrough!
You're welcome!
Thanks for making these guides, they have been very helpful.
A few notes on the stages I have finished so far:
2-1 Summary on this page says a single wave of 5 enemies. Should be a single wave of 4. (The detailed description is correct.)
3-3 Summary on this page says max 3 servants, but you can bring all 6. (There is a dialogue option remarking on it in the post-battle story too.)
The detailed description also says that you can only bring 3.
You can't replace the mandatory support Space Ereshkigal with your own. You can bring your own in another slot, if you want to (I didn't check to see if it locks her NP too.)
NPC BB Dubai doesn't need to be in the starting lineup.
Thanks so much! I've added the clarifications for the quest node details and in the walkthrough; they should be reflected on the live page shortly.
I used Andersen on 6-5 and he didn't kill himself off.
And thanks for the guide ofc!
Andersen is surprisingly hard-working. I've fixed the information drop down and the quest entry, it should update shortly!
7-4 says that Servants with the Can Fly in Space trait won't be stunned, and your site says that Penthisilea has that trait. But I brought her and she got stunned.
Thanks for pointing that out! She only has the "Can Fly In Space" trait when equipped with her Amazones CEO outfit, I've updated her page with a note under the traits to indicate this.
In St. 7-2, only 1 support servant is needed (if it matters, the support I used was my own Mash).
Thanks a ton! I've updated the description in the quest node and the walkthrough, it should update soon.
Unless I counted wrong, I wound up only spending 440 AP in the first section. Are the AP totals for the 2nd and 3rd sections going to be listed?
Also if it's not a bother, are there any plans to show the individual section reading lengths?
Thanks for the work regardless.
Thanks so much for pointing that out, the AP cost was entirely incorrect; I've added the breakdown for each Part (1, 2, 3) for both AP cost and for story length estimates. I should note that even though these are pulled from Atlas Academy, in my experience the length isn't always a perfect estimate and also depends a lot on individual reading speed.
The party restriction info for 13-5 is incorrect.
- You are only forced to bring two NPCs, not all three.
- There is no restriction on party size. You can bring a full team of 6.
Thanks so much! This should be fixed in the drop down description and in the quest node as well.
In St. 19-2, St. 19-3, and St. 19-4, personal servants can be used in place of the NPC servants.
