They are primarily nocturnal and sleep away the days in rocky holes or small caves. Humanoids living near a rattleback troll\xe2\x80\x99s lair often leave slain game as tribute at the entrance while it sleeps, in hopes that it will not go hunting too close to their village that evening. \n'b'  Venomous Killers . The rattleback troll\xe2\x80\x99s bite injects a debilitating venom that rots the flesh around the wound, preventing natural healing. When surrounded or attacked by multiple creatures, the troll expels a gout of this poison to drive off its attackers. Fortunately, the rattleback troll rarely enters a fray without shaking itself into a frenzy first, and the shell plates on its back give off a warning rattle before it strikes.'
