Etch Schema

 
Prerequisite(s): Caster Level 10+
 
Benefit: You can create a schema of a spell or infusion. Etching a minor schema takes one day for each 1000gps in its base price. The base price is its spell/infusion level X its caster level X 400gps. To etch a minor schema, you must spend 1/25 of this base price in XPs and use up raw materials costing 1/2 the base price.
