Co-Research with Chief Librarian ~Part Nine~ Event Banner
Introduction[]
Beat the enemies in the furthest reaches of the target tainted book and acquire coins.
After using "Chief Librarian's Fan," [the player] is able to delve as many times as needed until coins are acquired.
This is a special research event which will run from 2019/01/16 to 2019/01/30 13:59 JST. The purpose of this event is to accumulate coins.
Gameplay[]
How to play
Access this event by clicking on the event banner on the main library screen or the Book Delve section.
The event gameplay is similar to tainted book delving. However, you will need to use up a Chief Librarian's Fan to access the event bookshelf, and you will only collect coins from a delve once for each fan.
You will receive one fan per day by simply logging in, and you may also purchase fans in the shop. There are two special sets you can buy which comes with a Decor piece each to decorate your Office.
Once you have accessed the event bookshelf, you will note that there are three books. Book 1 (on the left) is of the lowest difficulty, and Book 3 (on the right) is of the highest. As stated on the event page, Book 1 yields 100 coins per completed delve, Book 2 yields 200, and Book 3 yields 300 no matter which route is taken by your team.
Tips[]
- You need only reach the farthest node in the book (either boss node or another branch) to collect the coins. Therefore, branching does not matter, and furthermore, you need not "purify" the book either.
- As stated above, one fan is officially used up only when you have successfully collected coins from a delve.
- The special gold bookmarks obtained here are limited-time items to be used in the upcoming transmigration event and will expire after the transmigration event ends.
