This section of the Tower is shaped like an Arena. Here, hunters can fight some Tower-dwelling creatures, such as Silver Rathalos, Gold Rathian and Kirin. It is reached by jumping off the Tower from your starting point, which appears to be Area 4 of the traditional Tower, but can only be reached in very specific Quests. In this area's camp there are no bed and no box which means supplies are never dropped off during the quest. Only 1 gathering point is in the area which is located on the east wall and contains Battlefield Jewels and Decayed dragon scales.
Tower 3 makes a return in Monster Hunter 3 Ultimate, where rare species such as the Lucent Nargacuga, Gold Rathian and Silver Rathalos can be fought. It is also the only place where Elder Dragonbones can be gathered.
