The Ethereal

Your patron is one of the rare beings who calls the Ethereal Plane their home - an ancient ghost or spirit, a powerful phase beast such as a Phase Spider Matriarch or a Shadow Hound who've mostly shed their material forms and grown into unthinkable incorporeal powers. Such a being might offer patronage as a way to regain some control within the Material Plane, and their gifts most always come with a price.

Making a pact with a being of the Ethereal Plane in this way might come from a search for knowledge or a quest for freedom from your mortal shackles - or such feelings might come after the pact is made. Ethereal beings are able to traverse the Border Ethereal as a passageway between the inner planes as well as view places in those plane unseen from their ethereal forms. Regardless of your patrons nature, you will learn to unravel secrets of the Inner Planes which might otherwise be inaccessible to mortal minds, and you will in time learn to attune your material form with your ethereal one.

3rd	phantom steed, sending
4th	arcane eye, phantasmal killer
5th	legend lore, mislead

Bonus Cantrip

At 1st level, you learn the message cantrip. It counts as a warlock cantrip for you, but it doesn't count against your number of cantrips known.

Breaching the Border Ethereal

Starting at 1st level, when you hit an enemy with a spell or attack you can teleport it to a space within 20 feet from you.

Once you use this feature, you can’t use it again until you finish a short or long rest.

Ethereal Reaction

Starting at 6th level, you can call on your patron to fade your body into the Ethereal Plane when you are attacked, transporting your material self to the attacker in the blink of an eye. When you are attacked, you can impose disadvantage on the attacker. When your enemy's attack is resolved, you can then make an attack of opportunity against your attacker with advantage. If your enemy is at a distance, you can choose to resolve your attack either where you were attacked or within 5 feet of your attacker. If you choose to expend your 'Breaching the Border Ethereal' feature when attacking in this way, you may choose to teleport your attacker within 20 feet of either where you were attacked or your attackers original location. 

Once you use this feature, you can’t use it again until you finish a short or long rest.

Ethereal Connection

Starting at 10th level, you can use this feature to cast the etherealness spell. In addition, you can cast the plane shift, but you can only choose the Ethereal Plane as your destination. When you do so, you can travel the Deep Ethereal in half the time it would normally take.

Once you use this feature to cast either spell, you can’t use it again until you finish a long rest.

 

Ethereal Projection

Starting at 14th level, your mind is in constant connection with the Ethereal Plane, feeding you information of your surroundings. You can no longer be surprised while on the Inner Planes, and you have advantage on all Wisdom (Perception) checks and Intelligence (Investigation) checks on the Inner Plane you're on after spending 24 hours on it.

In addition, you can now use your 'Breaching the Border Ethereal' feature twice before finishing a short or long rest. You can choose to expend both uses to increase the distance which you can teleport an enemy to 40 feet.
