Quality of a Photocard

Dear Class, welcome to Lecture 02, Prof. An here. I am glad that you were able to finish the first lecture and I hope you got to know more about the photocard system, please do not hesitate to ask questions or point out my mistakes. I am just a messenger that translates the ideas from the textbook to you all, so it is essential that we have an active classroom atmosphere.

Today, we’re going to talk about the QUALITY of a photocard.

Please feel free to SKIP this lecture, if you DO NOT care about the Shrine mechanics. If you solely collect Photocards for collections’ sake, the QUALITY of a photocard does not affect your experience besides a different number on the top left of the card.

Now some curious students may ask, what if I DO care about the Shrine and want to maximize my ODDs for success? Then I strongly suggest you to stay seated and I am going to cover exactly that.

First of all, let me give a definition:

Definition 01:

The QUALITY of a photocard is an integer in the CLOSED interval [1,10]

For an interval to be CLOSED, it means the endpoints are included. Hence, the quality of the card is ONE of {1,2,3,4,5,6,7,8,9,10}.

Or if you really wanna go fancy and flex your math knowledge, you can also say that the interval is closed if and only if the closure of the interval is itself. But hey! This is NOT Real Analysis so I don’t care.

Example 01: This Sailor Gaeul below has a quality of SEVEN (7), as denoted on the top left.

Before anything, I am going to provide you with the standard Rate of Offering because I’ll be mentioning things about it VERY frequently in this lecture:

There’re mainly FIVE situations where the QUALITY of the photocard is Useful:

1. To Flex to your friends or to your Mommy.

2. To REDUCE the chance of failure in a Shrine offering. (*Exclude Wisdom and Power)

3. To Tier Up a card you offer to the Shrine (*same as 2)

4. To provide a LOWER BOUND of the Quality of the output card in a successful offering (*Restrictions apply, see lower for more details)

5. To contribute to the Mystery Number you’re supposed to solve in the Shrine of Wisdom.

To be more clear, I shall demonstrate EACH situation with examples and Exercises. Buckle up, it’s gonna be hell of a ride.

Situation 1: Flexing in front of your friends or to your Mommy

Nothing much to say here, simply show your crush this:

And say, “Hey! I have a Quality 8 Gaeul 007! Do you have time tonight?”

Or show this to M… ahem… Prof. An:

And I’ll prob award you with Extra Credit in the Final. Damn, I look good in this outfit.

Situation 2: To REDUCE the chance of failure in a Shrine offering.

The description is pretty much self-explanatory. In Shrine of Health, Love, Fame, Fortune: the higher the Quality of a card offered, the LESS likely it will fail. Disclaimer: the MAIN factor of success or failure still depends on the type of the Shrine, and the impact from the Quality is NOT significant.

That is, a Quality 10 card in the Shrine of Fortune (which is the MOST difficult Shrine amongst the four above) will INDEED decrease the chance to fail, but expect something like from 50% Success to 60% (10 % for Q10) instead of a Guarantee of success. Since I am NOT the admin of the site, I cannot provide the exact number here.

One sentence summary using myself as an example:

“An Yujin 001, Quality 10 is more likely to succeed in an offering compared to another An Yujin 001 with Quality 1, under the assumption that the same type of Shrine is offered.”

Exercise 01:

My dear students, below is an easy exercise for you to test your understanding on this topic:

Which ONE of the following FOUR cards is LEAST likely to FAIL a Shrine of Health offering?

Solution: Liz 002 with Quality 9.

Hey, if you were able to answer this correctly in the first try without looking at the answer key? Good boy~ (Or Good Girl!) That means you’re a master in this subject, keep it up! Smart students might already be able to tell, which is something REALLY important:

QUALITY HAS NOTHING TO DO WITH RARITY!
