Bulwark behemoth

The Bulwark Behemoth is a boss monster that was released along with the Dungeoneering skill. It can only be encountered during Dungeoneering. The Behemoth initially starts out with extremely strong armour which cannot pierce through; in order to defeat the monster, attack the monster with a pickaxe, as the strong rock-armour of the Behemoth will slowly be chipped away until the creature can be damaged.

Trivia

 * The Gluttonous behemoth resembles an Ucamulbas or Ukanlos, a boss monster fought in the PSP game Monster Hunter Freedom Unite.
