Actions

1st Level, Signature Attack: Shank - 5ft range. +Expertise to hit (2d4 + 4 Piercing + Shanking).
2nd Level, Professional Shadow: you are an expert at shadowing other creatures. While you are in another creature's shadow, you move with them (up to your speed) and have Advantage on the first non-Stealth Check you make against them. Anything that would prevent you from staying in their shadow (such as being shoved, or knocked prone) removes you from their shadow.
3rd Level, Garrote: each time you succeed a Strangle check, the victim suffers 3d6 Slashing damage as part of that Check.
4th Level, Lurking Danger (3/day): deal piercing damage to a creature you are Shadowing. This damage is 1d6 per level you have. This does not ignore armor, though it does have the Shanking property (so it ignores armor on Grappled opponents, crits on Pinned opponents).
5th Level, Knife Storm (1/day): each enemy within 10ft must succeed a Dex Save (DC is equal to your AC) or suffer 1d4 per level Piercing damage.
6th Level, Never There to Begin With (3/day): one creature you have just spoken with must succeed an Int Save or forget the conversation within a few minutes. In the future, they have Disadvantage on any attempts to remember any details about the conversation, including who they were talking to and what it was about. This is not a magical effect, and cannot be "healed" with modify memory. You just don't stick in people's memory.
7th Level, Shia-surprise (1/day): vanish in a puff of shadows, appearing in the shadow of another creature you can see within 60ft. Immediately make 2 Attacks or Grapple Checks against them.
10th Level, Shadow of Death: when you critically hit a target while you are within their shadow, they must succeed a Constitution Save vs your DC. If they fail, they immediately drop to 0 HP and fail 1d4-1 Death Saves (if they don't die outright).
