In Hittite mythology, Ubelluris, also known as Upelluri, was the mountain god who carried the western edge of the sky on his shoulders and dwells in the bottom of the Persian Gulf and supports the land and sea.
In Hurrian mythology, Upelluri was the "dreaming god" that was extremely dense, such that when the gods had placed the stone giant Ullikummi, he was unaware of his burden. On top of that, even when the heavens and the lands he was supporting split, he didn't notice at all.
Ubelluris can be contracted during the daytime in Ikebukuro. Enemy variants can be found in Shibuya's Quartz gold level instance and Ueno's Mirage instances.
The most reserved Tribhvana member, Tribhvana: Earth, initially takes the form of Ubelluris during encounters. They stick to physical attacks, which aren't that dangerous by themselves. However, if Ganga is still active in the battle, the attacks will critical if she manages to affect a party member with Freeze or Shock. They are first encountered on the 20th floor of the Karma Society Tower.
The Tribhvana try to ambush the party again on the 32nd floor, but not much has changed aside from the HP totals and access to a new enemy combo.
