When they woge, Gelumcaedus gain thick, pale-green skin. Their mouths extend forward, widen, and become filled with razor-sharp teeth. Their hair and outer ears retract, and they gain sharp claws.
Physically, Gelumcaedus are incredibly powerful, able to tear a man's limbs clean out of their sockets and cause multiple fractures simply by shaking them. Their grip is nearly impossible to escape. They are durable creatures, able to withstand great force. They are also able to move with incredible speed for their large size.
Gelumcaedus are exceptionally hardy and adapted to living perfectly in dark and severely fetid conditions without any noticeable health problems as a result.
