Light Cones
Light cones are sorted from strongest to least strongest. Superimpose levels are in brackets.

Flowing Nightglow (S1)
Every time any 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 times. When the wearer uses their Ultimate, removes Cantillation and gains Cadenza. Cadenza increases the Wearer's ATK by 48/60/72/84/96% and all allies' DMG dealt by 24/28/32/36/40%, lasting for 1 turn(s).

For Tomorrow's Journey (S5)
Increases the wearer's ATK by 16/20/24/28/32%. After the wearer uses their Ultimate, increases their DMG dealt by 18/21/24/27/30%, lasting for 1 turn.

But the Battle Isn't Over (S1)
Increases the wearer's Energy Regeneration Rate by 10/12/14/16/18% and regenerates 1 Skill Point when the wearer uses their Ultimate on an ally. This effect can be triggered after every 2 uses of the wearer's Ultimate. When the wearer uses their Skill, the next ally taking action (except the wearer) deals 30/35/40/45/50% more DMG for 1 turn(s).
