Leo stared down at the monster’s head. This would be a tough shot, but he had no choice. He raised the vial in his left hand. He pressed his right hand against the tentacle and summoned fire to his palm—a narrowly focused, white-hot burst.
That got the creature’s attention. A tremble went all the way down the tentacle as its flesh blistered under Leo’s touch. The monster raised its maw, bellowing in pain, and Leo threw his Greek fire straight down its throat.
After that, things got fuzzy. Leo felt the tentacle release them. They fell. He heard a muffled explosion and saw a green flash of light inside the giant pink lampshade of the monster’s body. The water hit Leo’s face like a brick wrapped in sandpaper, and he sank into darkness. He clamped his mouth shut, trying not to breathe, but he could feel himself losing consciousness.
