Nightwalker

A quick work of combining aspects of different subclasses to create a guerilla, shadow magicy rogue.

Night Eyes

At 3rd level, you gain darkvision out to a range of 60 feet. If you already have darkvision from your race, its range increases by 30 feet.

You are also adept at evading creatures that rely on darkvision. While in darkness, you are invisible to any creature that relies on darkvision to see you in that darkness.

At 7th level, your acclimation to the shadows has grown, you can now see through magical darkness to a range equal to your darkvision range.

Cloak of Night

When you choose this archetype at 3rd level, you gain the ability to cast Darkness a number of times  equal to your proficiency bonus without material components. You regain all uses of this ability on a long rest.

Night Walk

At 9th 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 attack you make before the end of the turn.

Night's Embrace

At 13th level you gain the ability to cloak you and your companions in the shadowy embrace of night. Choose a number of creatures equal to your proficiency modifier within 30ft of you, they gain a +10 bonus to Dexterity(Stealth) checks and can't be tracked except for magical means.

One with Night

 At 17th level you have learned to take on the aspect of night. 

 As a bonus action, you assume a shadowy form. While in this form, you gain the ability to move up, down, and across vertical surfaces and upside down along ceilings, while leaving your hands free, and any attack rolls have disadvantage against you. You also gain a climbing speed equal to your movement speed and can also move through creatures and objects as if they were difficult terrain, but you take 1d10 force damage if you end your turn inside a creature or an object. 

You stay in this form for 10 minutes or until you end it as a bonus action.
