Path of slapstick

A barbarian of slapstick has constant wackiness happening to and around them, and often this cartoonish chaos turns bad luck to good luck for the barbarian, even if it means slipping on dragon poop. Many legendary slapstick barbarians exist, such as Jingles, lord of pies, Zippy the wacky, and Bingo, destroyer of worlds.

...Wackiness ensues

At 3rd level, your path to ultimate wackiness begins. You gain a number of slapstick points® equal to your extra rage damage. You may use a slapstick point® right before you make an attack or skill check to give yourself advantage on the attack or skill check.

14th level improvment option: at 14th level, whenever you use a slapstick point®, you regain 1d10 hit points.

Ultimate comedy form

At 3rd level, you begin your journy to ultimate wackiness. Whenever you make an attack while raging, you may use a slapstick point. If you do, you may cast Tasha's hideous laughter on the of the target of the attack. If the attack misses, the target automatically fails the saving throw. If the attack hits, the target gains advantage on the saving throw.

14th level improvment option: the target of Tasha's hideous laughter gains disadvantage on the saving throw if you hit with your attack.

Dumb luck

Somehow, as you rage, you are able to force reality to work out in your favor. While you're raging, a natural one counts as a natural twenty, and any attacks against you that roll a natural twenty count as a natural one as you accidentally slip out of the way of the attack.

14th level improvment option: at 14th level, you no longer need to be raging for this benefit, and 19s count as natural ones for any attacks against you.

Major annoyance

At 10th level, your general presence can become annoying to your enemies. You may use a slapstick point as a bonus action to force a creature to make a wisdom saving throw or have disadvantage on all targets other than you, and has advantage on attacks against you (a natural twenty while you're raging still counts as the higher number, despite being worth a natural one). The DC for the saving throw equals 8 + your profiency bonus + extra rage damage. You gain a bonus to your AC equal to your rage damage against the target creature.

14th level improvment option: creatures affected by this feature no longer have advantage on attacks against you.

Ultimate idiocy

At 14th level, your tomfoolery has reached it's peak. You may improve two of the features gained so far, and the other two at 20th level.
