The horns are heavy and are used in a swinging or butting fashion to defend themselves or kill prey of sufficient size. The back carapace is actually a wing-cover, though these beasts are far too heavy to take to the air. If highly threatened, however, a rhinoceros beetle will spread its wings and beat them rapidly enough to buffet the air around them, creating a 360° windstorm around the creature with a radius of 2 combat hexes (10 feet). Creatures smaller than 300 lbs. will be blown out of this circle and take 4-6 buffeting damage, half if a save vs. breath weapon is made. Creatures between 300 and 750 lbs. will be forced back one hex; creatures larger than 750 lbs. will be able to stand their ground.
Larvae are deposited under a large tree following a savanna fire, where they gestate below ground before eating their way into the trunk of the tree. Once the tree dies, the beetles (usually between 4-6) will emerge with soft bodies, growing to full size within about eight weeks. It is not known how the subterranean larvae are gestated.
When hunting, the rhinoceros beetle approaches cautiously, moving at normal speed before launching itself forward at double speed, ramming with its horn. These creatures are not known to act in groups.
