Quirky

Your unique personality throws others off balance and occasionally leads to unexpected advantages.

• You are really intelligent in a certain subject that interests you, as a result your Intelligence score increases by 1 and you choose to gain proficiency in Arcana, History, Nature, or Religion depending on your interest. If you are already proficient in your choice you gain expertise in that skill. Unfortunately you don't know when to share about these facts and are typically bad with people. Your Charisma score decreases by 1 as a result.
• Offbeat Aura: As a bonus action, you can do something wildly unexpected—like juggling mid-fight, quoting a random fact, or making a bizarre sound. One creature within 30 feet that can see or hear you must succeed on a Wisdom saving throw (DC = 8 + your Intelligence modifier + proficiency bonus) or be distracted, giving them disadvantage on their next attack roll or ability check. You can use this feature a number of times equal to your proficiency bonus per long rest.
• Eccentric Luck: Once per long rest, when you fail an attack roll, saving throw, or ability check, you can roll a d6. On a 5 or 6, you succeed instead, thanks to some inexplicably quirky twist of fate (like tripping forward into a successful strike).
