How to encounter Mighty raid in-game
For 7-Stars Raids to be findable by players, they must first have unlocked 6-Stars Raids through story progression. This requires completing the entire game story and the post game until the academy tournament. Players must then complete 10 4-stars or 5-stars raids.
Only after all these steps have been performed, the player will receive a call from Jacq, which he will proceed to tell you about dangerous black crystal raids.
