How to Get Breakthrough Materials
Collect Materials via Breakthrough Paths

Collect the Breakthrough materials corresponding to each Role. The Breakthrough Paths are prepared for each Role, so you need to clear the Paths that match the character you are training.
Obtain from Events and Paid Packs

Breakthrough materials can also be obtained from event rewards and some paid packs. In these cases, you will receive items like the "Breakthrough Selection Box", which can be exchanged for materials for a specific Role.

Obtain Higher-Tier Materials by Converting

Converting is one of the features under Crafting, and it allows you to combine lower-tier materials into higher-tier ones of the same Role. There is no downside to converting these materials, so be sure to make use of it for your character Breakthrough.
Convert Materials in Crafting
| 1. | ![]() |
| 2. | ![]() |
| 3. | ![]() |
| 4. | ![]() |
You can find Convert under Crafting mode, where you can also exchange 2 low-tier materials of another type to get your desired/specific Breakthrough materials. This is not recommended in the early game when materials are generally scarce, but consider it when you have a large amount of materials for a specific Role.
Benefits of Breakthrough
Stats Increase

When you perform a Breakthrough, base stats like ATK, DEF, and HP will increase. Also, the level cap is raised by 10, allowing for further strengthening through leveling up.
Unlock Slots for Monsterlings

Breakthrough increases the number of Monsterling equipment and unlocks the 2nd and 3rd slots. Equipping an enhanced Monsterling leads to a significant increase in power, so don't forget to equip them.
Obtain Starlight Crystal

As you advance a character's Breakthrough, you can receive Starlight Crystal as a reward for each character. By fully performing a Breakthrough on one character, you can obtain a total of 75 Starlight Crystals.
