Wolf Pearl: Features rate-up for Rossi (6★). Other possible 6★: Tangtang, Yvonne, Ember, Lifeng, Ardelia, Last Rite, Pogranichnik.
Weapon banners: Each banner spotlights a rotating 6★ weapon. See above table.
Pity and Headhunting Permits: Standard pity system applies; full details not specified in official materials.

Should You Pull? F2P & Spend-Rational Guidance

Both Tangtang and Rossi debut as new 6★ operators, and their banners will not overlap, letting players make a clear choice—and avoiding split pity risks.

If you’re F2P or low-spend, prioritize Tangtang early in the phase, especially if wishing to maximize the use of free Headhunting Permits from events and beginner tasks.
Consider saving for Rossi if their toolkit better fits your main team’s synergy; compare event rewards and roster needs—official materials list both banners' pools transparently, which is favorable for resource planning.
Weapon banners: Only commit if you’re flush with currency or have completed core roster goals—these banners aren’t as forgiving for F2P users.
Reminder: Event-exclusive Headhunting Permits (from [Beginner's Chartered Tribute], [Gently Flows Qingbo], [Pearl of the Pack]) can only be used on their related time-limited banners. Plan your resource usage accordingly.
