Gift of the Shadow Dragon (Wisdom)

You’ve manifested some of the power of Shadow dragons, granting you the following benefits:

Ability Score Increase. Increase your Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.

Grasp of the Shadow Dragon. As an action you can be pulled into your shadow by the shadow dragon. You take on the silhouette of a dragon shadow. For 10 minutes you can travel unseen in dim light or darkness. You can leap between gaps in shadows up to 10 feet wide. With a successful DC20 Intelligence (Investigation) check a creature can discover you in your shadow form. If there are no longer any shadows large enough to hold your shadow (min of 5ft) then you are immediately cast into the nearest unoccupied space. Once discovered you are also cast out of your form. You can use this feature as many times as your proficiency bonus per long rest.
