A spitting felldrake usually pauses to spit acid before closing to melee. It can spit acid up to 30 feet as a ranged touch attack with no range increment.

Because of its snaky body, a spitting felldrake can squeeze through small spaces. Thus, it is ideal for the underground expeditions so contrary to elven nature. The spitting felldrake is slightly larger than its crested cousin. Its body is long and sinuous, like that of a snake.
