Jade Phoenix Cheatsheet+Swift Actions+Fuse Style
At 1st level, a master of many styles can fuse two of the styles he knows into a more perfect style. The master of many styles can have two style feat stances active at once. Starting a stance provided by a style feat is still a swift action, but when the master of many styles switches to another style feat, he can choose one style whose stance is already active to persist. He may only have two style feat stances active at a time.
