Goliath's heat attack seems to be like a laser sorta?

I hit the ground just short of it, changing my course to evade another lash of its trunk. I fell to earth on all fours and immediately Lunged for its face. I saw its mouth open, swirling shades of light gathering between its teeth, and spun in midair, Levant pulling the wind around me to shift my course. What came from its mouth wasn’t fire, as such—my father had always described it as some deadly, invisible heat attack, but I could see it, now that I wasn’t blinded by being its focus. The Goliath didn’t just breathe heat; it fired a rush of energy from infrared to ultraviolet, and maybe even a small amount of even higher radiation. The swirl of colors between its teeth were nothing more than some of that energy spilling out as random visible light, little more than a side effect.
