You have learned how to channel your sutra casting in a different way than usual.

Choose: Charisma or Intelligence.

Benefit: You use the chosen ability score, rather than Wisdom, to determine the number of sutras you can cast each day. Other aspects of sutra casting (including the number of sutras you can know, the saving throw DC of sutras you cast, etc.) are still dependent on your Wisdom score, as normal.

Normal: You may cast a number of sutras per day equal to your Wisdom modifier, plus one for every four levels you have in a sutra casting class.
