Not sure where i got it from just cleaning out an old character:
silver-edged indigo sheet
MB: 1k
CB: 100k solded
Invoking this indigo sheet will grant you permanent access to a special method of preparing your spells.
It will provide the following phrase:
First Person: Clawing its way violently up your throat, the power of your [Spell Name] spell purges from your esophagus in a vicious tidal wave of raw energy...
Third Person: Geedunk powerfully purges his spell from his esophagus in a vicious tidal wave of raw energy...
Hidden or Invisible: Violent and powerful, the sound of mystical power fills the area like a tidal wave of raw energy.
