Barroth is a Brute Wyvern introduced in Monster Hunter 3. It is known to inhabit desert environments and can be encountered at low, high, and G-ranks.
Barroth is a large, bipedal monster characteristic of the Brute Wyvern class. It is noted for the large crown structure atop its skull, which houses its nostrils. Its body is covered in rigid plates of armoured hide that help protect it from the harsh desert environment. Barroth possesses a pair of small red eyes and a mouthful of long, peg-shaped teeth.
Barroth is capable of using its heavy head as a plow to smash through the environment, as well as cause damage to any living thing caught in its way. Because its nostrils are located on top of its head, Barroth can completely submerge itself in the cool mud during the scorching desert days.
It will occasionally roll in dirt and mud, possibly to cool off from the hot desert sun. Although docile by default, Barroth becomes extremely territorial when disturbed. It will release an initial warning roar. If that fails, it will continuously attack until the threat is exterminated. An insectivore, it is known to attack Altaroth nests in order to feast on the occupants inside.
Barroth is uniquely adapted to a desert lifestyle, and as such can almost exclusively be found in the Sandy Plains, although it has been known to wander into the Moga Woods occasionally.
The Guild Sweetheart says that a blunt weapon, such as a Hammer, must be used to break off Barroth's head ridge. It's not required to use a Hammer in order to do so, but due to the fact that the head crest is hard bone, it's much easier with a Hammer. Hammers are the only weapons capable of not bouncing off Barroth's head if under blue sharpness (unless the Mind's Eye skill is activated, or the Hunter is using the Spirit Slash on a long sword). She may just be hinting to the player of this mechanic.
