Gift of the Draconic Lair Action

You’ve manifested some of the most powerful traits from your Draconic heritage, granting you the following benefits:

• Your draconic heritage allows small glimpses into the future, granting advantage on attack rolls, ability checks, and saving throws until initiative count 20 on the next round.
• Magical fog billows around one creature you can see within 120 feet. The creature must succeed on a Wisdom saving throw or be charmed until initiative count 20 on the next round. DC = 8 + Constitution + Proficiency

After you've used both effects from this feat, you can’t use it again until you complete a long rest.
