Personality Parasite

Telepathy [Mind-Affecting]

You attempt to briefly partition the mind of your foe, calving off a minor personality that is antagonistic to the main personality. The parasitic personality functions with complete autonomy from the main personality. It does not control the body physically, but it can take one standard action each round that is purely mental, such as manifesting a power, in the same turn that the subject takes its normal actions.

The parasitic personality manifests powers using the subject’s power point reserve and known powers. It can also cast prepared spells, use available spell slots, or other esoteric abilities but only if they can be used with purely mental actions, as the parasitic personality is not able to perform somatic movements, provide material or focus components, or other such restrictions. It can only manifest powers or cast spells three or more levels lower than the highest level of power the subject can normally manifest or cast.

The parasitic personality actively attempts to manifest powers or cast spells that negatively impact the subject, using the highest-level powers or spells possible (so as to deplete the subject’s power point reserve and available spell slots), and the most deadly to the subject. You do not have control over what the parasitic personality does, though it always works against the interest of the subject.

Both minds communicate with each other telepathically. If a creature is targeted by a compulsion or charm effect while under the effect of this power, it can make a second saving throw if the first one fails. If both saving throws fail, then this power ends and the creature is affected by the charm or compulsion effect.

The parasitic personality does not gain any advantages if the main personality is subjected to a haste or schism effect.
