The Boss of the Abyss has a few weaknesses that you can exploit, but be warned: they're not exactly the most... shall we say, 'diplomatic' of creatures.
- Its sheer, existential dread of being alone in the universe.
- Its tendency to get distracted by shiny things.
- Its crippling fear of... actually, no, that's not a thing.
- Its inability to resist a good, existential crisis.
Exploiting these weaknesses will require a delicate balance of psychology, misdirection, and possibly a well-placed, cosmic event horizon.
