This feat originally appeared in the Expanded Psionics Handbook. It is expanded here.
Prerequisite: Manifester level 3rd
Benefit: In addition to the effects listed for this feat in the Expanded Psionics Handbook, you gain the following benefits:
You can create impression crystals, which store imprinted forms for use with [Formbound] effects. The base price for an impression crystal is the maximum number of forms it can hold multipled by 2000 gp. For example, if you wanted to craft an impression crystal to hold up to 10 forms, it would cost 20,000 gp. Crafting an impression crystal takes one day for each 1,000 gp in its base price. To craft an impression crystal, you must spend 1/25 of the item's base price in XP and use up raw materials costing one-half of its base price.
You may create mindstones, which allow a manifester to se a psionic power that he does not otherwise know. The base price for a mindstone is the level of the highest-level power it could bestow with its power point limit, squared, times 1,000 gp. For instance, to create a mindstone that allows up to 13 power points to be spent on its stored power, you would need 49,000 gp (as 13 pp is high enough to manifest up to 7th level powers). Crafting a mindstone takes one day for each 1,000 gp in its base price. To craft a mindstone, you must spend 1/25 of the item's base price in XP and use up raw materials costing one-half of its base price.
This feat also lets you mend any broken or damaged cognizance crystal, impression crystal, or mindstone that you could create. Doing so takes half the XP, half the raw materials, and half the time it would take to craft the item in the first place.
