Mystic Persistence (Su)
Replaces: Empty Body
At 19th level, a ki mystic can create an aura once per day as a swift action at the cost of at least 2 points of ki. The aura emanates out to a 20-foot radius. The monk and all allies within the aura can roll two dice when making an attack roll or a saving throw and take the better result. The aura lasts for 1 round, plus an additional round for every 2 ki points spent when the monk created the aura. The monk can dismiss the aura at any time as a free action, but the ki points for the full duration of the aura are lost. This ability replaces empty body.
