Bad health is not something that normally magics its way into someones life. They normally end up causing it on their own through doing bad things like smoking. As we both know, that often ends in terrible things for them, including death. Welp, you're in luck. Is someone annoying you? Is someone acting like a horrifying little [ ____ ]? Hey, there's a revenge tactic, now! Just pour some into their next berry smoothie and/or Starbucks drink and poof, they're lying on their death bed. And you can act innocent and offer them some coffee for their head. AHAHAHHAHA, what's up music reference. Ok, now go buy my potion.
