Knife juggler

Knife jugglers are rogues that try to distract there enemy with a blend of hiding and making sure enemies can’t ignore you so you’re friends can get the drop on them.They can jump in and out of the shadows disorienting foes and be flashy as they stab people in the back.

Surprise attack

When you attack a creature that didn't know where you where on its last turn or if its the first time you attack that creature it must make a wisdom save. If it fails it becomes surprised until its next turn. Surprised is a condition that only this subclass can inflict. A surprised creature has disadvantage on all saving throws and attacks against them have advantage.

Distraction

Any enemies within 15 feet of you must make a wisdom save. On a fail they are unable to attack anyone except you until the end of there next turn and on a critical failure they must use their next action to move as close to you as possible. If you do this more than 5 times during the same fight you take a level of exhaustion.

Roguish assistance

Once per short/long rest if a party member gets advantage on an attack you can add your sneak attack damage dice to their damage and subtract the lowest role.

Performance

Any friendly creatures within a 15 foot radius get any fear conditions removed and for the next minute can’t get disadvantaged on attack rolls.

Surprising agility

Whenever you use cunning action all enemies must make a wisdom save against being surprised.
