Nightshroud

Imbued with the shadow energies of the Shadowfell, the nightshroud are able to easily dance in and out of battle, using their own black magic to gain the drop on their foes.

Dark Sight Starting at 3rd level, your attunement to the Shadowfell allows you to see in the darkest conditions. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. If you already have darkvision, its range is increased by 30 feet. Your ties to the Shadowfell make your darkvision unusual: everything you see in darkness are shades of blue and purple.

Shadow Assault Also at 3rd level, you can easily elude enemies when going for the kill. After hitting a creature with a melee weapon attack and dealing your Sneak Attack damage to them, you can use your bonus action to vanish from their sight. You become invisible to that creature until the start of your next turn, or until you attack or cast a spell.

Living Shadow At 9th level, the essence of the shadowfell invested in you fuels you. You no longer need to eat or drink. Additionally, you no longer need to sleep and can't be forced to sleep by any means. To gain the benefits of a long rest, you can spend all 8 hours doing light activity, such as reading or keeping watch.

Spectre's Jaunt At 13th level, you're able to manipulate darkness to the point that you can shift your very form through it. When you use your Shadow Assault feature, you can teleport to an unoccupied space that you can see within 30 feet of you that is in dim light or darkness.
