Your knowledge is more than plain smarts—it's inspired.
Prerequisites: Int 13, 1 rank in at least one Knowledge skill, no levels in a class that has the inspiration class feature.
Benefit: Like an investigator, you have the ability to augment your Knowledge, Linguistics, and Spellcraft checks. You gain a pool of inspiration equal to your Intelligence modifier. You can expend one use of inspiration as a free action to add 1d6 to the result of a Knowledge, Linguistics, or Spellcraft check, as long as you are trained in that skill (even if you take 10 or take 20 on that check). You make this choice after the check is rolled and before the result of the roll is revealed. You can use inspiration only once per skill check. Your pool of inspiration refreshes each day, typically after you get a restful night's sleep.
Special: If you later gain levels in a class that has the inspiration class feature, you can immediately trade this feat for the Extra Inspiration feat.
