First, not a PFS question you may have better luck in the advice boards.

Second, to my knowledge the only way is the canny dodge ability, which is granted by either the Kensai magus archetype, or the Duelist prestige class.

Bladed Scarf Dancer Magus archetype too

aka not many be a duelist or a magus.

You just asked this question a few days ago. You should consult that thread for answers.

Old DnD feat, not in Pathfinder, Kung Fu Genius allows Monks to use their INT bonus instead of their WIS bonus.
