Blade in the Night

Character Operations Manual pg. 85
You have learned how to damage your foes not just with light, but also with the absence of light. As a move action, you can choose a creature within 30 feet of you. For 1 round, or until you leave graviton mode, you gain a +1 bonus to weapon damage rolls against that creature. This bonus damage increases by 1 at 8th level and every 6 levels thereafter. While attuned or fully attuned, this bonus damage instead increases by 1 at 4th level and every 4 levels thereafter.
