Improved Psicrystal [Psionic]
You can upgrade your psicrystal.
You can implant another personality fragment in your psicrystal. You gain the benefits of both psicrystal personalities. Your psicrystal's personality adjusts and becomes a blend between all implanted personality fragments. From now on, when determining the abilities of your psicrystal, treat your manifester level as one higher than your normal manifester level.
You can gain this feat multiple times. Each time, you implant a new personality fragment in your psicrystal, from which you derive the noted benefits, and you treat your level as one higher for the purpose of determining your psicrystal's abilities.
