Here is a practical three-part strategy that I recommend: You will strike this attacker in the throat with the hardest weapon available to you. Perhaps it is an elbow. Perhaps it is an 1847 edition of The Encyclopedia of Celestial Navigation. Perhaps it is a small, strange bird of infinite plumage, or a monstrous iron implement once used to prod the sacred tortoise in the savage jungles of Uln. Perhaps it is all these things. It depends, ultimately, on your inclination and talents, and also on the size of the purse one carries.
