Whirlwind Lesson

You can quickly browse through a magical tome or manual, gaining its benefits with only a single 8-hour study session (rather than the usual 48 hours over a period of 6 days). At 7th level, you may allow another character to join in your study; both of you gain the full benefit of having read the book. At 15th level, you may share your whirlwind lesson with a number of characters equal to your oracle level. The benefits to you are permanent, whereas your students gain the tome or manual's benefits for a number of days equal to your Charisma modifier but then forget what they have learned.
