Selling this spell prep from EG

Invoking this indigo-veined vellum will grant you permanent access to a special method of preparing your spells.
It will provide the following phrase:

First Person: Placing the fingers of your left hand upon the back of your right, you slowly trace out a pattern on your rosy skin and watch as an ethereal light illuminates your veins. Slowly, methodically, you intone the familiar words of [Spell Name] and watch as the patterns dance like eels beneath waves before discharging into a fine mist in the air.
Third Person: Placing the fingers of his left hand upon the back of his right, Sentral slowly traces out a pattern on his rosy skin and an ethereal light begins to illuminate his veins. Slowly, methodically, Sentral intones a soft prayer and the patterns, which now dance like eels beneath waves, suddenly burst from his flesh in a fine mist.
Hidden or Invisible: As a slow, methodical prayer finishes from somewhere nearby a fine, indigo mist fills the air.
