Your Wings of Light allow you to take to the air. As a bonus action, you can expend a charge of light to ascend 20ft into the air.  Every turn or every 5ft you move, you drop down 5ft. Dashing extend the distance to every 10ft. You can expend additional charges to go higher or faster. Each additional expenditure will either bring you up another 20ft into the air or increase the distance to 20ft. The number of charges is equal to your Constitution Modifier (Min. of 1). You regain spent charges by staying near sources of light. The amount regained is dependant on the strength of the Light source. A candle will grant one charge per hour/short rest(DM choice). A camp fire will grant two charges per hour/short rest (DM choice).
