The Orudakoitans can be found in various places throughout the main network of ruins on Kattelox as well as the Sub-Cities, however they do not appear in the Main Gate or the three Sub-Gates.

They are easy targets because they are set in position. Orudakoitans are somewhat like radar, as they spot the enemy and then alert their accompanying Arukoitan as to where it is. Once the Orudakoitan is blown up, the Arukoitan is useless.

There is a case where Orudakoitan are not paired up with an Arukoitan, in which case they are used for shooting fireballs.
