I am going to actually allow DJ to see the red glow on the edge. It would be something that stands out. I won't allow him covering the distance required to avoid the fire wall. It won't burn you as much as hoped because of the ice. However, it will create a steaming effect that can damage you. Regardless of the damaging factor, steam or fire, you do have to take some damage. More than just a singed tail. 

You will have to rewrite the post to mention the increased damage taken by your running dodge.
