Rolling for the gacha
To roll for the gacha you must have Prism jewels. Prism jewels are divided between paid jewels and free jewels. A single roll costs 250 Prism jewels (regardless of whether or not it is free), while a 10 roll costs 2500 Prism jewels. Free Prism jewels can be obtained in many ways:
- Doing missions
- Doing all daily missions will give out 100 jewels
- Also, doing regular/special missions can give you jewels as well. Full list here.
- Doing events and special activities
- Box Events usually give out 800 Prism jewels from the event gacha and 500 Prism jewels from completing missions. Ranking rewards also give out jewels.
- Challenge Tour can also give out rewards if you succeed in meeting certain criteria
- Reading story commus can give you 50 Prism jewels
- Ranking up in Score and Technical Score ranks can also give out jewels
- Certain promos and real life events can also give out codes that can give away free jewels.
Paid Prism Jewels, on the other hand must be bought, either through credit card or via Google Play/App Store. Paid Prism Jewels must be spent on the platform where they were purchased.
