One of your ancestors was a shadow demon. Its black ichor courses through your veins, giving your skin a dark tinge in color. You gain the following benefits:

• Increase your Dexterity score by 1, up to a maximum of 20.
• You have advantage on any Stealth checks you make when in dim light or darkness.

• As a bonus action, you can sprout a pair of shadowy wings and gain a flying speed of 30 feet as long as your not wearing heavy armor or are encumbered. The wings last for 1 minute, after which you must finish a long rest before you can use this ability again.
