Gachas are a way for players to acquire more cards. New gachas are typically introduced with new events; the rate-up cards in these gachas will have both the character and attribute bonuses for these events.
List of gachas
Pity
In permanent gachas (gachas that use the green seal to spark), there is a pity system that guarantees a 4☆ card once a certain number of points is reached. At 50 points, any 4☆ card available on that gacha is guaranteed. At 100 points, one of the rate-up cards for that gacha will be guaranteed. To get points, roll on the banner. For every roll only using paid crystals, players will get 1 point toward their pity meter. For all other rolls, players will only get 0.5 points toward their pity meter. This means that if there a roll that uses both free and paid crystals, that roll will only contribute 0.5 points towards the pity meter. For 10-rolls, treat each of the rolls in the 10-roll as a singular roll to calculate points.
Spark
Rate-up cards can be sparked on their banners using 300 seals. Seals are earned by rolling on the banner; each roll gives the player one seal. Players may optionally use up to 10 seal exchange tickets to lower the number of seals needed to spark. Each seal exchange ticket counts as 10 seals. This means that players may only need 200 seals to spark a card if they have 10 seal exchange tickets.
