You can forge your mind blade from a mixture of mental and soul energy, enabling you to deal devastating strikes with the weapon.
Prerequisite: Con 13, ability to form a mind blade.
Benefit: Once per day, you can invest essentia into this feat. You can expend your psionic focus when making an attack with your mind blade to gain an insight bonus on the damage roll equal to 1d6 per point of invested essentia. You must decide whether or not to use this feat prior to making the attack roll. If your attack misses, you still expend your psionic focus. Once the amount of essentia invested is chosen, it cannot be altered and remains invested for 24 hours.
You gain 1 point of essentia.
