The Hexenhammer Archetype gets a class ability called "Withering Gaze" which states:
Beginning at 1st level, whenever a hexenhammer successfully demoralizes a creature as a standard action, instead of applying the shaken condition, she can apply the effects of the witch evil eye hex as if she were a 1stlevel witch (save DC = 10 + 1/2 the hexenhammer’s inquisitor level + her Wisdom modifier).
The duration of a Evil Eye hex is 3+Int Mod, normally.
I am curious if, due to the will save being modified to use wisdom instead of intelligence, the duration would use wisdom instead of intelligence as well.
Technically, it'd use Intelligence.
