Undying Echoes

Echoes of those who have died surround you.  As an action, you can step into the plane of the dead to contact a ghostly presence for its knowledge for one minute.  This works like a Speak with Dead spell, in which you can ask a spirit up to 5 questions.  While you are communing with the dead, your physical body is deaf and blind for this interaction.  Once you use this feature, you can't use it until you finish a long rest.
