As a bonus action, until the end of your turn, you can magically allow yourself to fade into the Ethereal Plane, which overlaps with the normal, physical Material Plane.

An ethereal creature is invisible, insubstantial, and capable of moving in any direction, even up or down, albeit at half normal speed. As an insubstantial creature, you can move through solid objects, including living creatures. An ethereal creature can see and hear on the Material Plane, but everything looks grey and ephemeral. Sight and hearing onto the Material Plane are limited to 60 feet.

You can use this trait a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

You have Darkvision with a range of 60 feet.

You have advantage on saving throws against disease and being poisoned, and you have resistance to poison damage.

You have advantages on death saving throws.

You don't need to sleep and magic can't put you to sleep. You can finish a long rest in 4 hours if you spend those hours inactive, motionless state, during which you retain consciousness.

You have proficiency in the Insight, Perception, or Survival skill.
