Core Mechanics

Gem income scales with Story Mode progress. Higher chapters yield more Gems per completion. Using Fortunate-trait farm units increases passive Gem generation. Summer Currency is a seasonal resource earned alongside Gems during events.

Advantages

Free-to-play players can farm enough Gems to summon rare units within days. AFK farming in Infinite Mode provides passive income while away. Codes provide instant large Gem boosts.

Challenges & Weaknesses

Gem farming becomes repetitive. AFK methods require a strong enough team to survive Infinite Mode waves. Summer Currency farming is limited to event periods.
