War Jester

Most rogues prefer the shadows to hide themselves, but a few strange few known as War Jesters thrive on attention and the distraction they can bring. They use a wide variety of strange and often theatrical trick and elements to confuse an enemy. This leaves openings for their allies to strike where the defenses have been distracted.

Jester First

At 3rd level, you know how to put on a brilliant performance that will keep all eyes on you. You gain proficiency in performance and deception if you do not have them already. Additionally, whenever you are performing, any creature that can see you has a penalty to Perception (Wisdom) checks equal to your Charisma modifier. 

Laughing Blade

At 3rd level, you know how to royally piss things off. Whenever you deal sneak attack damage to a creature with a melee attack, you may have the creature suffer disadvantage on all attacks not made against you until the end of its next turn. Additionally, the next attack against the creature not made by you has advantage until the start of your next turn. 

If you use this feature on the same creature two or more times within the same day, they can attempt to make a DC 8 + your proficiency + you Charisma modifier Wisdom saving throw to not suffer disadvantage on its attacks. 

Trickster's Powder

At 9th level, you learn sometimes angering everything you see is not the safest act. So you now keep a bag of special magical powder to help get out of, or into, those nasty situations. As a bonus action, you may throw a pinch of powder onto the ground at your feet and gain the benefits of the Invisibility spell until the start of your next turn. 

You may use this feature a number of times equal to your charisma modifier. You regain all expended uses after you finish a long rest. 

Dance of Daggers

At 13th level, you are quick with a joke and even quicker with a blade. You gain a special reaction that you can take on every creature's turn, except your turn. Whenever an ally attacks a creature with advantage and you are adjacent to the target creature, you may make a melee weapon attack against the same creature. These extra attacks cannot deal sneak attack damage. 

Deadly Distraction

At 17th level, you really know how to make a good opening. Whenever you use your Laughing Blade feature against a creature, you mark them until the start of your next turn. Whenever an ally hits the marked creature while you are adjacent to it, you may use your reaction to cause the attack to become a critical hit. You cannot use this feature on the same creature again until a day and an hour has passed since you last used it on them.
