Spectre Cover

Whenever you successfully use your Blessing of the Raven Queen feature, all friendly creatures within 5 feet of your teleport destination receive resistance to all damage and other creatures have disadvantage on Wisdom(Perception) ability checks to notice you and them, until the end of your next turn.

Additionally, you can use your Blessing of the Raven Queen feature as a reaction instead of bonus action, when you or one of your allies within 35 feet are targets of an attack or are forced to make a Dexterity saving throw.
