Craft Cognizance Crystal [Item Creation]
Manifester level 3rd.
You can create a cognizance crystal. Doing so takes one day for each 1,000 gp in its base price. The base price of a cognizance crystal is equal to the highest-level power it could manifest using all its stored power points, squared, multiplied by 1,000 gp. To create a cognizance crystal, you must spend 1/25 of its base price in XP and use up raw materials costing one-half its base price.
