Gems are the premium currency in this game. They can be earned in-game by:
- Clearing a quest for the first time
- Stepping on every platform of the map (you do not need to search them)
- Completing Missions, including Daily Missions
- Log-in bonuses
- Participating in special events
Other than that, the only method of acquisition is to buy them with real-life money.
Gems are used for:
- Summoning weapons from the gacha
- Fully restoring AP (not recommended)
- Restoring party HP when defeated in combat - some quests do not allow this usage, or restrict it to only a certain number of occurrences (not recommended unless desperate for a specific quest reward or spending a good amount of money)
