I guess I mis explained it? She's trying to force a spike of ground up through one of the heat points, creating a jet of melted earth.
Hm, interesting. That's kind of a pain in the ass, but I'll have to work on it. My plan for possibly drenching the fire hounds in some kind of coolant is unlikely to work. Let's try a hollow shell, tungsten again since it's got that nice melting point. A nice several meter sphere, just a few centimeters thick. If I can create it, I try to see if I can change its shape once created, perhaps a rapid compression to crush whatever's inside?
Next, I try to rip a huge swath of earth up, possibly as a shield or bulwark.
Lastly, I experiment with chemistry again. I don't know much about the exact metallurgy or various chemicals, but I do recall some basics from the elemental table. Anything in line with hydrogen will explode on contact with water, and I know fluorine is incredibly toxic. Maybe some acids? Hm, hydrochloric is the only one I recall off the top of my head, maybe some of the other ones will come to me. First, let's try some sodium, but I want to create it a few feet away from me, as it's rather violently energetic.
