What's unfair about a robot succumbing to an arena hazard? I added that in there because nobody in all of FanFic had ever done it. Also, with the high-temperature titanium and Hardox alloys in use nowadays, the Thermite wouldn't burn a hole through the armour that easily. It's only effective against robots with either thin armour(3-3.5mm), or weak armour(Aluminum, Polycarbonate). It's not designed to be effective against most robots, it's designed to put in a new idea.
