Ogir - Yensa Sandsea The Ogir - Yensa Sandsea is a location in the land of Ivalice in " Final Fantasy XII " . It is a desert to the far west , where the sand flows like water . The Urutan - Yensa are the only humanoids who live in the Sandsea . A peculiar race , not much is known about them due to their hatred of outsiders . They have a hard exoskeleton , and walk very quickly . They have a queen , implying they are comparable to an insect - like society . Built by the Rozarrian Empire , the giant oil rigs around the sandsea were built to drill oil from the sea . Because of interference by the Urutan - Yensa , Rozarria abandoned them and travelers use them as walkways to cross the desert . Story . After Princess Ashe has been rescued from onboard the Dreadnought " Leviathan " , she decides to pursue the throne of Dalmasca . To prove her lineage as royalty , she needs to obtain the Dawn Shard in the Tomb of Raithwall . The party accompanies Ashe on her quest through the Sandseas . They must cross the sandsea on foot as it is located on a Jagd and thus Balthier ' s airship does not fly there .

In the west of the area the player can descend stairs to ground level , and on the very west of that area there can spawn a treasure that may have the Mace . In the northeast of the area there is a junction , and the treasure that spawns in the middle may have the Handaxe . The path that ends in a dead - end to the west may have the Zwill Blade or Spear , and the dead - end to the east may have the Cypress Pole or Capella . The treasure in the northwest of the map , right before exit to Primary Tank Complex , can have the Chopper . In the Primary Tank Complex , in the southeast dead - end , the player may find a Iron Helm . In the very east of the area the player may find the Ringmail . Around the second to last oil rig , before the bridge that leads to the last oil rig before exit to Platform 2 - Refinery , the player may find the Iron Armor .

Rare Game . To find the Bull Chocobo the player must have spoken to the " Huntmaster " in Phon Coast and defeated Thalassinon , which will trigger the start of the Rare Game quest . The Bull Chocobo then has a 40 % chance of appearing in the South Tank Approach . With the exit and enter approach , it will spawn eventually . Pineapple has a 20 % chance of appearing in the Platform 1 - Refinery area . There are numerous spawn points where it may appear , and where in the area it appears is random , meaning the player has to search the entire area to see if it has spawned . To spawn the Urutan Exile , the player needs to kill at least 100 Urutan - Yensa while in Ogir - Yensa Sandsea . The Urutan Exile then spawns in Ogir - Yensa Sandsea / Platform 2 - Refinery atop the main building . The player does not have to chain 100 Urutan - Yensa , just kill them . Killing 100 Urutan - Yensa does not guarantee that the Urutan Exile will appear , however , as there is a certain percent chance for its spawn . The Urutan Exile has a low chance to drop the Osafune , a powerful weapon when the player first crosses the Sandsea , so chaining the Urutan - Yensa to increase the chances of acquiring the katana is still highly advised .
