Flowing Nightglow

Every time an ally attacks, the wearer gains 1 stack of Cantillation. Each stack of Cantillation increases the wearer's Energy Regeneration Rate by 3/3.5/4/4.5/5%, stacking up to 5/5/5/5/5 time(s). When the wearer uses their Ultimate, removes Cantillation and gains Cadenza. Cadenza increases the Wearer's ATK by 48/60/72/84/96% and increases all allies' DMG dealt by 24/28/32/36/40%, lasting for 1/1/1/1/1 turn(s).
