Great Balls of Fire!

With a fluid motion, I drew the sword at my side, and as soon as the tip of the blade left the sheath, my whole hand and arm felt a heat emanate from it. However, my movements had been too swift to take in what had happened right away. The first vampire who had been cut down went up in flames and the sound of their screaming rang through my ears. My eyes were wide as I looked at the blade that was engulfed in flames. I wasn't familiar with the legend of the sword, but no wonder this thing was so potent despite being so damned old.

"Well, things are getting a bit hot, might be a bit of a scorcher today," I half-joked and then looked back to the last four vampires who had paused in their attack for a moment. Then with a bit more of a serious look, I continued, "are you sure you don't want to turn around now?"

The four hesitated with glances between them all, but their fear of their leader outweighed their fear of me and they charged me again, bearing their fangs.
