Night Sorcerer

A child of the goddess of night, her divine blood flows through you allowing you access to a modicum of her power.

Primordial Progeny

You can reach through shadows, allowing you to cast touch spells at 15ft range increasing at later levels.

Font of Shadow

As an action, you can spend 2 Sorcery points to cast darkness, pass without trace, or silence, without providing material components.

Shadow Step

At 6th level, you gain the ability to step from one shadow into another. When you are in dim light or darkness, as a bonus action you can teleport up to 60 feet to an unoccupied space you can see that is also in dim light or darkness. You then have advantage on the first touch spell attack you make before the end of the turn. (this used to be melee since I copied it from the shadow monk, but let me know if its not kosher being a touch spell attack)

Assured Night

Once per long rest, you can swap day to night (what else should this do, maybe thats enough?)

Umbral Form

Starting at 18th level, you can spend 6 sorcery points as a bonus action to magically 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.
