After hearing this, I had to try it out right away. xD So, I went to my best game were all of the characters had all their jobs mastered, deleted one of them and bought a recruit to try this on. Got them to a time mage and turned my magic user, with Time Mage mastered, to a Squire and used Slow 2 on the Time Mage and it didn't work. So, I took the Setimesin, however it's spelled, off my time mage and tried again with Haste 2. It worked. The games asked me if I wanted to learn the spell. Amazing. I played this game so much and thought I knew everything about it.
