Lurking in misty jungles and along dark riverbanks, the boalisk is a vile serpent that can cause death and pestilence with but a gaze. A boalisk is a constrictor snake 12 to 30 feet long with dark scales interspersed with pale green and yellow daubs of color to help it blend in with its surroundings on the forest floor. The eyes of a boalisk are large and reddish in color.
A boalisk hunts by grabbing prey with its mouth and then squeezing with its powerful body. More powerful opponents (or if the boalisk has recently eaten) will be attacked with the boalisk’s gaze attack.
