Forgive me if this is out of place, I categorize this as being relevant to baneful magic.
First off I’ll establish the usefulness of this. Many magical teqniques that are baneful require anger, now usually if you desire to use these spells, you are already angry. However I’ve found sometimes this is not the case… As a sufferer of PTSD it may be a problem only I encounter, but sometimes people like me lack capability for emotion. This is problematic. I have been vexing a target for awhile, trying again and again, not only do I have the PTSD problem, but my anger is dwindling, my will is still sure I desire his demise. my emotion does not reciprocate. I imagine control in conjuring emotion could be a useful skill. Whether it be anger, or any other emotion, but I can find no instruction or thought into developing emotional control beyond the silly new age pansy “finding happiness” crap. There is nothing on conjuring what people think are negative emotions. I wouldn’t be posting here if I had found anything on that, and I don’t think I’m alone in the desire for control of the full spectrum of emotions.
