Monk Schools (Pathfinder Alternate Class Feature)
From D&D Wiki
Level: 1 to 20
Replaces: Wisdom bonus to all class features and effects relating to his monk class.
Benefit: Choose one school: School of the Eagle (CHA), School of the Fox (INT) or School of the Bear (CON). A Schooled Monk can use either her Charisma, her Intelligence or her Constitution rather than her Wisdom to determine all class features and effects relating to his monk class (this is valid for the Style feats the Monk might take too)
