Path of the Shattered

Path of the Shattered Barbarians are many entities that inhabit one body. They may be a singular person with multiple personalities, a hydra with multiple heads or cursed with being possessed by several beings or a person trained in several multiple disciplines. But these are just suggestions, get as creative as you want!. Either way, these barbarians have access to a plethora of options that allow them to become a versatile combatant and a great amount of utility in exploration and social settings, always dependent on their mood and a healthy amount of luck.

Level 3: Lvl 3: Shattered Mind

When you become a Path of the Shattered barbarian, you designate three distinct personalities that your character may take, including your normal personality if you desire, you give them an order from 1-3. When you acquire this ability and at the end of every long rest from now on, you roll a d6 to determine the dominant personality until your next long rest or until something happens that would cause you to change personalities(specified later on):
1-2: First personality
3-4: Second personality
5-6: Third personality

The personality rolled determines the main way your character may act for the duration. Different personalities always have some discriminating factor, be it a visual or physical change, the way they talk, walk or their moral compass. A creature that has seen all of your personalities and knows you are afflicted with multiple personalities can attempt a dc 20 wisdom (Insight) check as a study action to determine which personality is the dominant one in that moment, you can choose to cause a creature to automatically succeed on this check if you believe the change is obvious enough. A creature that witnesses you change personalities can attempt a dc 20 medicine, arcana or history (You or your dm may choose one or more of these as viable options depending on the origin of your personalities) check to diagnose your condition on a success.

When you reach Character level 10, you gain a fourth personality which you add into your rotation, roll a d8 instead of a d6 whenever you would decide a dominant personality, add in your forth personality as the result for rolling 7-8.

Level 3: Lvl 3: Archetypes

Your personalities alter the way you fight, think and act, assign one of the following archetypes to each of your personalities, you cannot repeat archetypes between personalities and these archetypes can't change after you pick them. In special occasions, a personality might undergo circumstances that may warrant a change of archetype, if you believe this is the case, disregard the rule about not being able to change. The archetype of a personality determines most class features, which you can only access while that personality is the dominant one.

Brute: A Brute personality is generally simple-minded and straightforward, Brute personalities focus on general improvements and play most similarly to a stock barbarian.

Tactician: A personality with the Tactician archetype provides the most battlefield utility in the form of a commanding presence that allows them to gain a strategic advantage.

Gentle: A gentle personality may exemplify the more subdued  and subtle aspects of a person, gentle personalities focus on tanking by drawing fire away from their allies.

Arcane: An arcane personality may be a representation for the passions or natural gifts of a person. arcane personalities have a particular affinity towards magic, offering limited magic options that can prove very useful in specific circumstances.

Diplomat: Diplomats are the channel of communication between minds, diplomats lack many direct benefits combat benefits but excel in social situations and are able to facilitate changes in dominance between personalities.

Villain: A villainous personality is the darkest corner of a person's psyche, villainous personalities focus on brutal damage output and rolling high.

Hero: Inversely, a heroic personality is the embodiment of the altruistic traits of a person. Heroes excel in supporting their allies and banishing evil.
