Soukaku gathers Vortex, then uses Fly the Flag to pass an ATK buff to the next attacker. Three stacks strengthen that support and add Ice value, but collecting them takes field time.
ATK handoff support with additional Ice amplification.
Build three Vortex through EX or Chains, use Fly the Flag, and send the buff to the intended carry through the prompted assist.
Vortex upgrades the ATK transfer and enables the Ice bonus, making preparation more valuable than repeatedly using an unstacked flag.
Pass the buff through the Quick Assist or Chain rather than extending her own attack sequence.
EX / Chain builds Vortex → Reach three stacks → Fly the Flag → Quick Assist to carry → Use the buff window → Rebuild
Ultimate grants all three Vortex stacks.
At maximum core, 2,500 initial ATK reaches the doubled buff cap.
Ice or Section 6 compatibility enables the Ice damage bonus.
Plan the handoff before stun so setup does not consume the carry's best seconds.






Useful when reducing Ice buildup resistance benefits the carry.


Meet her buff requirement before investing in personal damage.
