Combustion Inducement

If you can get only one talisman from Jackie Chan adventures which one would you pick?

I'm trying to understand how volatility works, it's confusing to me. So there are explosions, combustion, and volatility, but I don't know the difference. What makes one better than the other, and what is volatility supposed to do?

The ability to shoot a powerful blast of flames from one's own hands, but the flames are in multi-coloured.

So this random guy hacked physics and Saw Manipulation and started abusing it, so the developer wanted to give him a special punishment and gave you the option to kick his buttocks with (temporary) powers of your own. The options being Combustion Inducement, Light Solidification, and Air Pressure Generation. There may or may not some pretty simple solutions with these (definitely with CI), but I encourage you to be creative with your responses.

I haven't posted anything in a while and felt like I should so I'm going to ask how you'd beat someone with water form manipulation, and as an option, you can explain how you'd actually counter their powers. Options for powers are going to be air manipulation, violence empowerment, and combustion inducement. try to be creative if you want.
