Among all the items launched by the Black Beacon, the Keystone is absolutely the most precious one, and it is closely related to everyone's various activities in the game. Today, I will introduce in detail what the Black Beacon Keystone is used for. Only by understanding the purpose of each item in the game can you truly leverage its advantages. Let's take a look at the specifics below.

The Keystone can only be obtained through in-game purchases. When you make your first purchase, you get double the amount; that is, for 6 yuan, besides getting 60 Keystones, you also receive an additional 60 as a gift. So, it's best to take full advantage of the first purchase, making it the most cost-effective. After obtaining them through purchase, the next step is using them. Open the character outfit section, and you can see all the outfits currently available for sale here. These outfits also require Keystones to purchase, with prices generally being quite high, suitable for wealthy players.

For most players, they come to the Key Store to exchange for Search Keys and Mystery Keys. Search Keys are used for specific searches, which means limited pool draws, while Mystery Keys are used for regular searches, or permanent pool draws. Both of these items are essential for drawing cards in the game and are the main consumption targets. Each costs 150, so the card-drawing items in the game are relatively precious, so you must be cautious when drawing.

Finally, I'll introduce two events where you can obtain Keystones. The first one is Echoes of the Frontispiece, which requires clearing the exploration mode of the Book of Fate to get rewards such as Keystone fragments and Ancient Marks, and can only be activated after completing Chapter 3-18. Shadows of Time, on the other hand, can only be activated after completing Chapter 4-19, and by clearing the preparation area of the Boundless Stacks, you can get rewards like Keystone fragments and Moments of Infinity. Here, I'll also explain the relationship between Keystones and Keystone fragments: you can convert Keystones into Keystone fragments by exchanging them.

After reading my introduction, you should now understand what the Black Beacon Keystone is used for, and also clearly know how to obtain this item. In fact, there are still some in-game events that can also provide them, but for most players, if you want to meet your usage needs, moderate purchases are almost unavoidable.
