When you cast this spell, roll 1d6. Depending on the result, this spell grants an enhancement bonus to either Intelligence, Wisdom or Charisma, and a -4 penalty to the other two.
If a spellcaster receives a bonus to his primary ability score, he does not receive any new spells. However, a penalty may cause him to lose the ability to cast any higher-level spells or spell slots he hasn't yet used. Memorized spells are not erased, nor are inactive spell slots considered spent; they can be used when the spellcaster's ability score returns to normal.
Material Component: A sheaf of gilt-edged paper, with the words Intelligence, Wisdom and Charisma written on it in golden ink, costing at least 10gp.
