Hello fellow Timekeeper, Sonetto is here to help remove the shield from the Star afflatus enemy, she does so by using her Buff incantation. You can use anyone who gives Buffs like this.
Hello fellow Timekeeper, you can use any sustain. La Source, Dikke, Yenisei, Tooth Fairy, Ezra, etc. Balloon Party is used here for her Counter to remove the shields of the Mineral enemy. But Jiu Niangzi is strong enough to kill everything either way.
