Ethereal Resilience

Starting at 1st level the ethereal power you wield can protect you. When you aren’t wearing armor, your AC equals {{modifier:cha:+13#unsigned}}. Whenever you are reduced to zero hit point and don't die outright, you are transported to the Border ethereal until the beginning  of your turn. While in the border ethereal you are treated like you don't exist.

Warping Wave

Starting at 6th level, your kinship with the Border Ethereal increases,as does your mastery of your Ethereal wave. whenever a creature fails you Ethereal Wave saving throw, you may banish them to the Border Ethereal. while banished in this way they are on a different plane of existence are treated as though they don't exist, but they can see and move. At the start of their turn they can repeat the saving throw from your Ethereal Wave, on a success  they reappear in the plane the were on.

Innate Etherealness

The Etheralness spell is added to the list of spells you have known and prepared and it doesn't count against your number of spells known. you can also cast it once with this feature without using a spell slot or components per long rest.

ethereal banisment

Starting at 18th level, you can see into the Border Ethereal. In addition you may spend an action and 4 sorcery points to send a creature you can see in the Border ethereal into the deep ethereal.  A creature banished in this way has no statistical likelihood of finding you within a year. Stronger creatures may be immune to this effect.
