Dragon's Fire

It's nostrils flared as it dropped its head, each opening to the size of my skull. Its mouth followed as well

And then their was fire.

Yellow flames exploded and wrapped around my body completely.

"He didn't even try to dodge," screamed Bagman!

The crowd erupted. No longer seeing the Triwizard Champion. The Drip Tooth kept breathing its flame, until finally its nostrils closed, and so to its mouth.

"What has happened to Halfhwit," Mr. Bagman screamed, "Is he the first casualty?"

The flames subsided, and from the remains, I remained.

I took a couple steps forward.

"Wow, " Bagman screamed, "He doesn't have a mark on him. What is in that potion?"

It was true I wasn't on fire, but I still felt the heat of that attack. I kept my composure and approached the dragon closer. If it knew it affected me, it would likely try that again. I walked within twenty feet of the dragon, which had quit it's shaking display. We were past that. Now it was time to get the egg.

"The bravery of Mr. Halfhwit," Said Bagman, "To not only walk through a Drip Tooths fire, but to walk within it's striking distance like it's nothing."

What did he mean it's striking distance?
