Wreathed in Darkness

Starting at 1st level ,when you are successfully attacked, as a reaction you may blink 15ft instead of being hit. Your attacker is then blinded until the end of your turn unless they pass a charisma check contesting your spell casting modifier. You must complete a short rest before you are able to do this again. 

Shadow Meld

At 6th level, when preforming metamagic, you may turn invisible until the end of your next turn for an additional sorcery point. At level 8, the invisibility can be as though you cast the invisibility spell for 2 additional sorcery points. At level 14 both costs reduce by one point each. (the first tier is free, second tier costs 2 points)

Shadow Gate

Starting at 14th level. you may expend 3 sorcery points in order to open a gate of shadow. You and any creature of medium or smaller stature can fit through that you deem. If you permanently expend these points (you dont regain the points and instead they are again spent on the gate in order to maintain it) the gate stays open until you are killed. You may regain the points if you go to the gates location and dispel it.

Form of Umbra

Starting at 18th level, you can spend 6 sorcery points as a bonus action to transform yourself into a shadowy form. In this form, you have resistance to all damage except force and radiant damage, and you can move through other creatures and objects as if they were difficult terrain. You take 5 force damage if you end your turn inside an object.

You remain in this form for 1 minute. It ends early if you are incapacitated, if you die, or if you dismiss it as a bonus action
