Fight
Cinder misses.
Brogg techincally hits, but your broadsword bounces off the armor without making a scratch.
Dave FoO casts Dispel Magic. Good move, you delay the chainsaw attack for one round. The armored warrior stalls out and the chainsaw ceases to function.
Next round, Cinder misses again.
A bobcat is summoned. The bobcat misses, misses, and technically hits but again does no damage. It has, however, provoked the warrior, who revs up the sword again and saws the cat clear in half with a solid 14 hp of damage. (Perhaps the bobcat has met his 'crazy match'.)
