Shadow Assassin

You focus your training on the grim art of death. Those who adhere to this archetype are diverse: hired killers, spies, bounty hunters, and even specially anointed priests trained to exterminate the enemies of their deity. Stealth, poison, and disguise help you eliminate your foes with deadly efficiency. 

Always prepared

When you choose this archetype at 3rd level you also gain the ability to, as a bonus action, create an object of hardened shadow. This construct can take the form of your thieves tools, or a dagger. Objects created with this feature fade back to shadow when they leave the hands of the shadow assassin.

Shadow Companion

You have become so in-tuned with the shadow and darkness that you can form it into a companion of choice

Flowing Shadow

You gain the ability to seemingly disappear at will, you are able to use an action to turn into a shadow or turn invisible, while also making enough shadows appear to turn invisible if there are none. Any nonmagical light sources are extinguished, and you are able to attack without being noticed by enemies other than your target. This darkness last for up to 10 minutes, and can be summoned up to 3 times per short rest.

Shadow Step

At 13th 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 melee attack you make before the end of the turn.

Shadow Shift

At 17th level, you have become so attuned to the shadows, that you can create small pools of shadows around yourself at will. You can now use Shadow Step in any lighting conditions, not just darkness.

Shadow Surprise

Starting at 9th level, you are at your deadliest when you get the drop on your enemies. Making it so that any hit you score against a creature that is surprised (or attacked while you have advantage)  leaves them on 1 hp.

Master of shadows

At 17th level, you gain the ability to create a perfect illusion of yourself for 1 minute or until you lose concentration (like concentrating on a spell). You may control this illusion as a bonus action on your turn to move it up to 30 feet, and can even swap positions with this illusion as an action, but can only do so as long as you are in dim light or darkness. When created this illusion manifests itself anywhere within 30 feet of your choosing. You must stay withing 120 feet of this illusion or the ability fails. Once you use this ability, you can't use it again until you complete a long rest.

Silent shadow

At 13th level, your movements have become completely silent. While in dim light or darkness you make no audible noise. While in darkness, you are invisible to any creature that relies on darkvision to see you in that darkness. Foes with tremorsense have reduced range(half of the normal range) to detect you.
