One managed to be mostly below the water, when the fireball detonated, but the other took the full brunt of the blast. The two barreled forward to defend their nest, trying to rip Sak'bas apart, but she was able to deflect anything they threw at her. From there, the rest of the group was able to bring them down, easily enough, though the enormous corpses filled a large portion of the cavern. It was a snug fit for them, originally, but now the eight tons of dead monster did not help in the slightest.
