Phase 1: Si

Si is one of the two new 6-star Operators introduced in Version 1.6. She is a Cryo Supporter whose kit focuses on team support and Cryo synergy, making her a valuable option for teams that can take advantage of Cryo-related effects.

As a Supporter, Si is designed to enhance her teammates rather than focus purely on personal damage. Players interested in building Cryo-focused teams may want to prepare their Oroberyl before Version 1.6 launches.

Phase 2: Argent Flow

Argent Flow is the second new 6-star Operator arriving in Version 1.6. He is an Electric Guard focused on offensive performance and frontline combat, making him a strong option for players building Electric-based teams.

Players interested in Argent Flow should prepare their Oroberyl in advance before Version 1.6 launches.
