[@TheUnknowable]monsters in the darkness as well as shadow control The things he can do are no more dependent on the lights absence than his limits Ex:(things listed are not all he can do, these are just umbrella terms) Dawn-Day(umbral strength:Weak) He could fire shadow bullet Make darkness Construct small things from shadow Dusk(umbral strength:moderate) He could create make normal sised objects/weapons Fly Nightfall(umbral strength:Full power) He can do all of the above but much easier/stronger He can create nonsentient allies Make virtually anything he wishes He can create sentient animals(not allies, this concerns things like riding horses, shadow Phoenix's or anything rideable) Basically the light is a universal hindrance for his power, the sunlight is the biggest hindrance that is able to exist, artificial light such as flashlights or lamps, depending on their brightness would also be weaknesses, UV light is a grey area for this weakness, it is somewhere within the boundaries of the sunlight and an especially bright floodlight. Wow that took a fair bit of explaining ._.
