Hezrou attracted a lot of enemy fire.
Although their strength was only around 21, their Constitution could be close to 30, and they weighed more than 750 pounds. Although they couldn't compare with those big demons, they were still very dangerous in a battle. The Hezrou demon that led Solon's group was an advanced form. It had a large body size of more than 1200 pounds; like a small giant. But it was a pity that it looked very strange because it looked like a frog. Now it was like a roasted frog on the fire, and its disgusting skin was covered in char.
Hezrou was fighting a flaming demon; a rare kind of demon.
Under normal circumstances, a demon's evolution was like this: Dretch, Abyssal Skulker, Quasits, Succubus, Vrock, Hezrou, Glabrezu, Nalfeshnee, Marilith, Balor.
That's how humanoid demons evolved, but there were also more dangerous Bebilith and Retriever.
