You have discovered the dark and dangerous side of the mind that is buried deep within the subconscious.
Prerequisite: Ability score from your primary discipline is 15+ (Psychic Warriors, Strength 15+)
Benefit: From now on, your powers and psionic combat modes have become integrated with your subconscious mind. You can also activate subpsionic items without taking damage.
Add a +1 to all saving throws of powers you manifest from Metacreativity, Clairsentience, and Telepathy disciplines. You get a +1 bonus on manifester level checks to overcome power resistance for powers from these disciplines.
The subconscious mind proves less than optimal for powers from the Psychometabolism, Psychoportation, and Psychokinesis disciplines. Your effective manifester level for powers you manifest from these disciplines is lessened by -1. (Subpsionic characters cannot manifest powers from these disciplines if they are 1st-level characters.) The reduced manifester level affects the power's range, duration, damage, and any other level-dependent variables the power might have, including nullify checks against you.
From now on any psionic item you create is a subpsionic item.
Special: Knowledge of the subconscious mind has a price. When you acquire this feat, you must reduce one of your stats by 2 points. Restorative powers (such as true rejuvenation) do not reverse the stat loss.
