I was assuming from the Bipedal Rat that you can get a bonus here vs Fire Techniques but I am not getting that when roles are reversed:
You toss a bottle of burning liquid at the helidrone for 1 fire damage.
The helidrone fires a microrocket. It homes in on you and explodes in a brilliant display of light, dealing 8 fire damage.
You flick some flaming fuel onto the rat for 7 fire damage.
The rat tosses a bottle of liquid that turns the sparks on you into a blaze, dealing 12 fire damage.
