Sorry for the misunderstanding, for me SAG (sagesse) wich is in french is WIS (Wisdom) in English.

I decide Wisdom instead of Str because it not far from stunning fist like the monk or other pressure points. Also it will be used for 1 or 2 abilities that use Heal check. To help, I put a bit more fluff so you can understand the mentality of the class.

Have a nice day
