Harlequin

Laughing in the face of danger is an attitude which sets harlequin rogues apart from their peers. Some may have been jesters at a noble court, others unruly thieves who would mock their chasers from the rooftops as they made their escape. You can try to ask them how they learned their craft, but you’re likely to get nothing but an insult for your trouble.

Hurtful Ridicule

When you choose this archetype at 3rd level, your words hit quick and hard. You learn the vicious mockery cantrip. You also know the spell hideous laughter. You can cast this spell a number of times equal to your proficiency bonus and you regain all expended uses after finishing a long rest. Charisma is your spellcasting ability for these spells.

Hop, Skip, Jump

Also at 3rd level, when you take the Dash action, your movement is increased by 10 feet as you skip swiftly ahead. You can also jump over a Large or smaller creature without any additional cost to your movement as you set off from its back. In addition, when falling 15 feet or less, you can roll when you land as a reaction, landing on your feet and taking no damage.

You Missed!

Starting at 9th level, you laugh in the face of your opponent’s frustrations. When a creature misses you with an attack, you can use your reaction to cast vicious mockery on the creature. If the creature fails its saving throw against the spell, you can immediately move 15 feet away from it without provoking opportunity attacks

Wit-Based Reactions

Starting at 13th level, your charms exceed all expectations. You can use your reaction to add your Charisma modifier (minimum of 1) to any saving throw you make. You can add this number after you have seen the roll, but before you know if the roll was successful or not.

Jeering One-liner

At 17th level, the victims of your remarks become distracted by your words. After a creature has taken damage from your vicious mockery, you have advantage on attack rolls made against it for 1 minute.
