Change Emotions

A spell in the Auxilist or Exerist magic classes, this spell may change the way someone or something feels.  It can be used to change hate into love, sadness into happiness, or make someone less mentally weary.  (Reducing physical weariness would instead be found within the Virrist or Mutist classes.)  
Auxilist changes to emotions are long-term effects which slowly push the target toward the desired emotion, often by helping them see and give more weight toward reasons for feeling that way and being more likely to dismiss any evidence to the contrary.  The more supporting reasoning and less contrary considerations, the more potent the effect of such a spell would be.
Exerist instances of this spell, on the other hand, quickly modify the target's emotions to match the desired outcome, but have no effect on the long-term belief of the target.  If little supporting reasoning for the desired emotion exists, the emotion will fade over time.  Events that are likely to reduce the emotion will also continue to degrade the outcome of the spell, eventually returning the target back to their original emotional state.
