Wolf Pearl: Provides an increased chance to acquire Rossi (6★). Other potential 6★ operators include: Tangtang, Yvonne, Ember, Lifeng, Ardelia, Last Rite, Pogranichnik.
Equipment Banners: Each dedicated weapon banner highlights a specific 6★ weapon on a rotational basis. Refer to the table above for specifics.
Pity System and Recruitment Permits: The standard pity mechanics are in effect; comprehensive details were not explicitly outlined in official announcements.

Acquisition Strategy: Advice for Free-to-Play & Prudent Spenders

Both Tangtang and Rossi are introduced as brand-new 6★ operators, and their respective banners will be staggered, allowing players to make a distinct choice without the concern of split pity accumulation.

For those playing for free or with minimal spending, it is advisable to prioritize Tangtang early in the update cycle, especially to maximize the utility of free Recruitment Permits obtained from various events and initial progression tasks.
Consider reserving your resources for Rossi if their specific abilities and role align more effectively with your primary squad’s composition; compare event rewards and assess your current roster’s requirements—official communications transparently list the character pools for both banners, which facilitates efficient resource planning.
Regarding weapon banners: Only engage with these if you possess an abundance of in-game currency or have already achieved your core team objectives—these banners present a less forgiving acquisition path for free-to-play individuals.
A crucial reminder: Event-specific Recruitment Permits (from [Beginner's Chartered Tribute], [Gently Flows Qingbo], [Pearl of the Pack]) are exclusively usable on their designated time-limited banners. Therefore, plan your resource expenditure thoughtfully.

Information not disclosed in official materials includes exact summon rates or the future rerun schedule for these banners. Evaluate potential future banner competition by referencing the provided timeline and your personal acquisition plans.
