Jekyll and Hyde

Named after the infamous Dr Jekyll and Mr Hyde Story. Due to a dramatic or/and horrible past, the person formed multiple identities to avoid the memory. Once you gain a split identity your main character has everything while the split personalities has the same thing, except for name, alignment, personality traits, ideals, bonds, flaws, opinions, and/or memories.

After each long rest, you must make an Intelligence Saving Throw to remain in the personality that was fronting upon resting. While your hit points are below 40, you must make an intelligence saving throw at the end of your turn to keep the current personality active.

Upon failing the saving throw, you swap personality fronts and are considered stunned for your next turn.

The Hyde personality gains +2 to an ability score of your choosing upon receiving the split personality(This is not interchangeable on each swap)
