Wraith Strike

Starting at 3rd level, as a bonus action, you can surround yourself in mist -- teleporting up to 15ft into an unoccupied space within 5ft of a creature -- and make an attack with a wielded light weapon.

Wall Walk

When you choose the archetype, at 3rd level, your climb speed becomes equal to your walking speed, including any bonuses to your walking speed.

Supernatural Gaze

When you reach 3rd level, you also gain the ability to Charm an intelligent creature through supernatural means once per long rest. As an action, you can target a creature with an Intelligence of 3 or more that you can see with your eyes and force it to make a Wisdom saving throw. On a failure, the creature is Charmed by you as long as you maintain eye contact. When the effect ends, the creature does not know it was Charmed by you.

Charm DC = 8 + Proficiency Bonus + Charisma modifier

Shapechange: Mistform

At 9th level, you can use the vampiric art of shape changing to turn into a cold, damp mist (no action required) for the duration of your turn. While moving, you may take the form of mist, allowing you to move about undetected and fit through any gap. While in this form, you have a flying speed of 20ft, can hover, and can move through a hostile creature's space. If air can pass through a space, your mistform can do so without squeezing; however, it cannot pass through water. Moving away from a creature in combat grants the same benefits as a Disengage action. While in this form, you are immune to all nonmagical damage, and have advantage on Strength, Dexterity, and Constitution saving throws. As soon as you stop moving or your turn ends, you are unable to maintain Mistform and you return to your corporeal state.

Vampiric Blade

Beginning at 13th level, you may take an action to inscribe a bladed weapon with the runes of the Draconis Malisath, imbuing it with 3 charges. When you successfully hit an enemy with this weapon, you can expend a charge to regain 1d10 + Constitution modifier hit points. You may only inscribe a weapon once per long rest.

Vampiric Blade

Hitting a creature with runed weapon heals you when expending a charge.

Touch of the Malisath

Starting at 17th level, whenever you make a Sneak Attack, you deal an additional 1d8 damage + your Dexterity modifier to one creature. You immediately receive healing equal to the bonus damage done with Touch of the Malisath. If this kills the target of the attack, you use the ritual of the Draconis Malisath to absorb it's life force, gaining 2d10 + the target's Constitution modifier in temporary  hit points. You also gain a Proficiency of your choosing that the enemy possessed permanently. The next time you kill an enemy in this manner, you can choose to replace that Proficiency with a new one.
