Many rogues let fate blindly guide them, and many rogues die due to their blindness. You on the other hand choose to guide fate to the outcomes you wish to see. You look out at all possible outcomes of a battle and leave with the only possible outcome you see, victory.

Chosen Outcome

Starting at 3rd level, whenever you ready an action to attack someone you are able to use sneak attack against the target, even if you don’t have advantage and no other friendly creature is within 5 feet of the target. If you ready your movement to move in a specific direction no creature is able to attack you with their attacks of opportunity.

A Twist of Fate

Starting at 3rd level, you are able to slightly alter fate for you or another person. As a reaction you can allow yourself or someone you can see within 30 ft to reroll an attack roll, saving throw or ability check, you can choose to use this feature after you roll the die, but before the outcome is determined. The one rerolling has to use the new roll no matter the outcome.

You can use this feature a number of times equal to your proficiency bonus and regain all expended uses when you finish a long rest.

Fated Shock

Starting at 9th level, whenever you hit a creature with your sneak attack you are able to choose to attempt to stun the target instead of dealing your sneak attack damage. The target must succeed on a Constitution saving throw (DC equals 8 + your Wisdom modifier + proficiency bonus). On a failure the target is stunned until the end of your next turn. On a success nothing happens.

Split existence

Beginning at 13th level, when using your cunning action ability to hide, or dash you enter the border ethereal plane.

While in the border ethereal plane, you are able to move in any direction. If you move up or down, every foot of movement costs an extra foot. You can see and hear the plane you originated from, but everything there looks gray, and you can't see anything more than 60 feet away. While on the Ethereal Plane, you can only affect and be affected by other creatures on that plane. Creatures that aren't on the Ethereal Plane can't perceive you and can't interact with you, unless a special ability or magic has given them the ability to do so.
You ignore all objects and effects that aren't on the Ethereal Plane, allowing you to move through objects you perceive on the plane you originated from.

At the end of your next turn, you immediately return to the plane you originated from in the spot you currently occupy. If you occupy the same spot as a solid object or creature when this happens, you are immediately shunted to the nearest unoccupied space that you can occupy and take force damage equal to twice the number of feet you are moved.

You can use this feature a number of times equal to your Wisdom modifier, and you regain all expended uses at the end of a long rest.

Changed Fate

At 17th level, you learn to always look at all possible realities and outcomes and are always prepared for anything to happen. You gain the following benefits:

• When you use the Uncanny dodge feature you take a quarter of the damage  instead of just taking half damage.
• When someone within 30 ft of you is hit by an attack roll, you are able to as a reaction halve the attack's damage against them.
• You can't be surprised while you are conscious.
