ECHO HUNTER

Patience, persistence, and perception. An Echo Hunter's senses must remain finely tuned at all time. With little more than rumors, these stalkers use technology and insight to track their quarry throughout the systems in which they pursue them. They focus on hunting humanoids, often for bounties or other treasures. Whether or not their prey prefers to spend the rest of their existence in a cell or a ditch is up to them.

 

SHADOWED STALKING
When you choose this technique at 3rd level, you learn to strike from the shadows. While you are hidden and more than 30 feet from your target, the first attack roll you make each round does not automatically reveal your presence. Make a Dexterity (Stealth) check contested by your target's Wisdom (Perception) check. On a success, you remain hidden. 
 

ACCOMPLISHED AMBUSHER
Also at 3rd level, when you take the Attack action against a creature that is surprised, you can make one additional attack against that creature as a part of that action.

TARGET TRACKING
Also at 5th level, you may choose one humanoid as your target.  Gain advantage on all investigation and survival checks made when attempting to track this individual. During combat, you can deploy one drone as a bonus action to track your target. This drone can allow you to target your quarry even if your vision is otherwise impaired.

 

CONCEALMENT

Beginning at 7th level, you've become 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.

Additionally, when you hit a creature with a ranged weapon attack while hidden, you can force that creature to make a Dexterity saving throw against your tech save DC. On a failed save, the creature's speed is reduced to 0 until the end of your next turn. You can use this feature a number of times equal to your Intelligence modifier (minimum of one). You regain all expended uses when you finish a short or long rest.

 

LOCKED ON TARGET
Starting at 11th level, any attacks made on enemies that are tracked by your Target Tracking are done so with advantage. If you already have advantage, you may retain it and in addition, attack the target again. 

ECHO DRONE MASTER
Starting at 12th level, you learn how to utilize Echo Drones to their fullest. These drones are small devices that move on their own which can track either heat signatures or electrical frequencies for tracking droids. Deploying these can help you triangulate the general position of your target within 100 miles. They move to scan possible matches, transmitting back a match percentage.

They can move up to 60ft per turn in combat and be set to hover around a target, giving you advantage, hindering escape attempts, or detecting them after they have attempted to hide. You can have up to 3 at a time, each having a single hit point and 11 AC. 

Deployment: You can deploy one in combat as a bonus action each turn until you are out, or, all 3 can be deployed at once using a full action. If any of the original 3 are destroyed and you wish to acquire more, you must pay for repairs or for new models.
