Average gem gain + tips

Provided by a kind anon

A 10-roll costs a total of 300 gems.

Average gem gain:
- Tasks and goal missions: Varies, but it usually gives 10 each (except for the recently added “make a password for your account” and “tie a social media account” which gives 30 each)
- Main story episode that has a Battle or Rhythmic: 10 each
- Personal stories: 5-15 per card depending on rarity
- Weekly login bonuses: 60 total
- Weekly missions: 60 total
- Participating in events: Varies (The current event as of the date of this post gave a total of 120 gems)
- Character Birthday login bonus: 2 10-roll keys per month (Except on the months of March and July, as only one character has a birthday on those months)
- Player's birthday login bonus: one 10-roll key. Only applicable if you've inputted your birthday and login that day.

Tips:
- New player (less than 2 weeks): If you can afford to spend, buy the Magical Keys (10-set) for 200 paid gems + try out the Guaranteed SSR gacha for 300 paid gems. Do note how many paid gems are included in what you’re buying which is indicated with 有償 (unpaid is 無償).
- Regular players: Buy the Magical Key (10-set) every month from the shop for 250 gems. You save 50 gems and it comes with large star fragments to regain energy. You can also buy the set of 3 individual Magical Keys for 50 gems so that you’ll essentially be doing 1 10-pull with 3 additional solos for the price of 1 10-pull.
- Non-F2P Players: The Daily Paid solo pull only costs 10 gems vs. the regular 30 gems. It's recommended to use the daily paid solo-pull on the regular summoning gacha, as it stays there permanently and the 100 rolls counter never disappears. Add that up and it’ll only take 1000 gems in 100 days to fill up the counter vs. the regular 3000 gems. If you have 10k yen to blow, the biggest gem pack will fit this goal perfectly with 1000 paid gems + 230 unpaid gems.
