A sensei’s advice is identical to bardic performance (using oratory),
allowing him to inspire courage at 1st level, inspire competence at 3rd
level, and inspire greatness at 9th level, as a bard of the sensei’s level, usable a total number of rounds per day equal to his level + his Wisdom modifier (minimum 1).
At 6th level, a sensei may use his advice ability when spending points from his ki pool to activate a class ability (using the normal actions required for each) in order to have that ability affect one ally within 30 feet rather than the sensei himself. At 12th level, a sensei may affect all allies within 30 feet rather than himself (spending points from his ki pool only once, not once for each target).
At 12th level, a sensei may instead spend 1 point from his ki pool (as a swift action) while using advice to provide a single ally within 30 feet with evasion, fast movement, high jump, purity of body, or slow fall.
At 18th level, a sensei may spend 2 points to grant one of the
abilities listed above to all allies within 30 feet, or diamond body,
diamond soul, or improved evasion
to a single ally within 30 feet. These abilities function at the
sensei’s level and last 1 round.
This ability replaces the bonus feats at 6th, 12th, and 18th level.
