WANDERER OF THE NIGHT

You gain darkvision (60 feet, or +60 feet if you already have it). When you cast a sorcerer spell that creates an area of darkness, you can see normally within that area. Moreover, while you are in an area of dim light or darkness, you can use your action to become invisible, and lasts until you make an attack, cast a spell, or are in an area of bright light.

LIVING DARKNESS

You can take the Magic to summon a tamed Shadow Hound in an unoccupied space that is in dim light or darkness within 120 feet of you and choose its target. The Shadow Hound can only move towards its target and to attack it. The Shadow Hound disappears immediately after it or the target drops to 0 hit points, or after 10 minutes.

Once you use this feature, you can't use it again until you finish a long rest, unless you expend 3 sorcery points to use it again.

FORTRESS OF DARKNESS

You regain resistance to cold and necrotic damage. Moreover, when you cast a spell that deals necrotic damage, any creature within 10 feet of the target takes necrotic damage equal to your sorcerer level + your Charisma modifier.

SHADOW WALK

While you are in dim light or darkness, you can take the Magic action to teleport up to 120 feet to an unoccupied space you can see that is also in dim light or darkness.

UMBRAL FORM

You can take the Magic action to transform transform yourself into a shadowy form. In this form, you are immaterial except you don't have resistance to radiant damage. You remain in this form for 1 minute, or if you become incapacitated, you die, or you dismiss it as an action.

Once you use this feature, you can't use it again until you finish a long rest, unless you expend 6 sorcery points to use it again.
