對於亮晶晶好友判定規則
剛看了兩則 N 社的回覆[1][2]後整理一下：
```
var 亮晶晶好友機率 = 2% // (數字亂寫，參考就好)
if (!四心好友) { 滾; }
if (該友 === 藍圈) { 滾; }
if (好友清單中尚無藍圈) { 亮晶晶好友機率 += 1% }
if (random(0, 1) < 亮晶晶好友機率) {
歐咩爹都~

```
好吧，用白話文整理成三點： XD
* 好友藍圈一天只有第一次互動才會賦與（已知，舊有規則）
* 亮晶晶好友只有在四心好友上藍圈時，佛系判定 (機緣不夠，回頭是岸)
* 訓練師好友清單中的第一個藍圈，亮晶晶好友機率略高些（首殺加成）

Happy to clarify, Trainer. The chances of becoming Lucky with your Best
Friends are random. The possibilities are comparatively higher on your first
interaction of the day. However, you can still turn Lucky on your subsequent
interactions. Hope the odds are in your favor! ^SP

To clarify, only the first interaction you have with your Best Friend per day
could make you Lucky Friends, replacing increased Friendship levels. So, if
you and a Best Friend trade and later participate in a Raid on the same day,
only the trade could make you Lucky Friends. ^MM
