Lore Master (Ex)
At 5th level, the bard becomes a master of lore and can take 10 on any Knowledge skill check that he has ranks in. A bard can choose not to take 10 and can instead roll normally. In addition, once per day, the bard can take 20 on any Knowledge skill check as a standard action. He can use this ability one additional time per day for every six levels he possesses beyond 5th, to a maximum of three times per day at 17th level.
