Gravios

Gravios is the mature form of Basarios. Easily one of the largest wyverns found in the series. Gravios can put its enemies to sleep with a gas emitted from pores around its body. It can be found in the volcano and swamp. They are able to go in and out of lava without any damage done to them. Gravios eat rocks and minerals for their nutrients.

They can perform a devastating beam attack which cannot be blocked unless you have the Guard skill. Like their younger counterparts, they are still very slow due to their size. Besides their gas and lava attacks, they fight and move pretty much like the Monoblos or Diablos. Note that when in rage mode the Gravios will emit an explosive red gas instead of its usual sleeping gas. It is possible to cut off the tail (2 Carves) and smash open the stomach shell. The stomach can be broken twice and after the second time it will reveal the monster's muscle layers.
