Unassuming

A master of being unseen and unassuming, this rogue knows how to blend into its surrounding while still being in plain sight.

Lurker in the Dark

When you choose this archetype at 3rd level, you learn how best to exploit the cover of darkness to conceal your movements. While in dim light or darkness, you have advantage on Stealth checks.

Fade to Black

At 9th level, you gain the ability to vanish into shadows, appearing to fade out as you step between distant locations. As an action or bonus action while in dim light or darkness, you can teleport up to 60 feet to an unoccupied space you can see that is also in dim light or darkness. You can take the Hide action before or after you teleport in this way.

Unmeorable

At 13th level, you gain such a mastery of misdirection that attention slides off you like water off a duck's back. Hostile creatures searching for you have disadvantage on Wisdom(Perception) checks. You gain a new stat named "Passive Stealth", which is calculated by adding 10 + your Charisma modifier. Any creature with a Passive Perception below your Passive Stealth will not notice you unless you directly interact with it, or if notified of your presence by another creature.

Silent Existence

At 17th level, As an action you can completely erase your existence from a target creatures (within 120 feet) personal reality. The targeted creature must make a wisdom saving throw DC 8 + your proficiency bonus + your intelligence modifier, however the Stroke of Luck feature can be used to make the targeted creature automatically fail. Upon failure the target creature can not recognize your existence, they can neither see or hear you, and every memory they've had of you is erased, even if they are to come into physical contact with you they would not be able to tell where the physical contact had come from or explain it. This effect is permanent until you choose to end it, the target creature takes a cumulative damage from any of your actions equaling more than 10d10 (rolled upon activating this ability) or another creature successfully casts Wish upon the affected creature with the specific intent of undoing this effect. You can choose to end the effect at any time as long as you are on the same plane of existence.

As this is an effect on their mind and not any form of cloaking, any un-targeted creature is unaffected and sees you no differently than before. The maximum number of creatures you can have under this effect at any one time is equal to your intelligence modifier (min 1), if you have the maximum number of creatures under this effect then to use this ability again you must end the effect on one creature.   

Once this effect is ended all memories are returned to the creature and they are aware they were under the effects of some kind of magic.
