You have learned to attune your psicrystal to your akasha powers, treating it as a servant and vassal.
Prerequisites
Vassalage class feature, Psicrystal Affinity.
Benefit
You always treat your psicrystal as one of your vassals while it is in range of your demesne, and whenever one of your heraldries grants your unseen servants an ability, your psicrystal gains that ability as well. Daily uses of any abilities granted in this way are shared between your unseen servants and your psicrystal.
Special
If you gain the Superior Psicrystal: Attuned feat, you can choose the following effect instead of choosing the effects of a psionic class you possess: The range of your demense is doubled for your psicrystal when using the vassalage class feature and for determining the effects of title veils you bestow on it.
