One of the features the game offers is the in-game store, which has various items available to purchase. One of the items players can buy in the in-game store are Star Crests. Upon checking the description, players will notice that they are used for breakthroughs.

What are Star Crests?

Star Crests are breakthrough materials for legendary Aurorians. These characters are the members of the silent hunters, and they have Star Crests instead of Solambers. When looking at a regular breakthrough for other Aurorians, players will notice that they use Hearstone and Solambers.

Solambers are materials that a player will obtain for recruiting a duplicate character. However, the legendary Aurorians cannot be recruited through banners. This means that they have a different method in terms of getting their breakthrough materials. Instead, players will need to buy a Star Crest in order to make their character stronger.

How to obtain a Star Crest

The Star Crests are available for purchase in the in-game store. One Star Crest costs approximately 100 stellar gems.

How to use a Star Crest

Since the legendary Aurorians are not recruitable, players will have to use the Star Crest as their breakthrough material. The player needs to open their Aurorian page and choose breakthrough in order to use the Star Crest. The Star Crest will maximize the character’s strength.

Who are the legendary Aurorians?

Once the player completes level seven to 14 in the game’s storyline, they will unlock the Old Seal feature of the game. This feature will allow the player to recruit one of the legendary Aurorians. They are six-star units and are known as the Silent Hunters.

Players can also discover the legendary Aurorians by going to Ilustra, then choosing Personel Intel, then clicking on Independent, and choosing Silent Hunters. Once the legendary Aurorians are unlocked, they have maxed out ascension, which is quite powerful.

Only one Silent Hunter can be recruited, and players can choose between Forest, Fire, Thunder or Water.
