Today , numerous shrines are found across the Highwaste , but not all of them are operational . After fixing the gate in Salikawood that leads to the Phon Coast , the player can return to Mosphoran Highwaste to find some of the shrines working . Using the shrines , the player can build bridges to areas that were inaccessible before . The optional boss and Esper Exodus is found in the area in the middle .

The player should activate the " South Wind Shrine " south from the shop and an exclamation mark appears on the map . The player should take the northeastern exit from the Babbling Vale and use Gysahl Greens to mount the chocobo and ride it across the hidden path , indicated by the exclamation mark on the map , and go all the way to the west and cross through the high grass . The player should proceed around the lower part of Skyreach Ridge back into Babbling Vale . Next the player must activate the " West Wind Shrine " and push the weathered rock nearby to create a path , which leads back to the Gate Crystal .
