Well, me being me i’d most likely break his jaw a few ribs and quite possibly puncture one of his lungs next time i saw him, But admittedly i might have a shorter fuse then you and i get the feeling you want to avoid any jail time over it so i’d begin with this.
Then evoke Pazuzu for both protection and devastating this man’s life, he’s one of the best around for that and won’t kill anyone if asked not to. Or you could try something like this.
Calling on Naamah or Lilith for aid in this is also a good choice and they both so enjoy getting new playthings, but if you decide to work with the ladies then don’t summon Pazuzu at all, those currents don’t work well together.
