Time Waits for No One is a 5 star The Abundance Light Cones.

Morn, Noon, Dusk, and Night 

Increases the wearer’s Max HP by 12%/15%/18%/21%/24% and Outgoing Healing by 12%/15%/18%/21%/24%. When the wearer heals allies, record the amount of Outgoing Healing. When any ally launches an attack, a random attacked enemy takes additional DMG equal to 50%/62.5%/75%/82.5%/95% of the recorded Outgoing Healing value. This additional DMG is of the same Type as the wearer’s, is not affected by other buffs, and can only occur 1 time per turn.
