Jecht Sphere 1

In order to obtain this Sphere, go to the area where you defeated Spherimorph. If you can't remember the location, I'll help you. Return to Macalania Forest, the area right after the Thunder Plains. Once entering, go straigh up, avoiding the first turn to the right, and go past the 2 treasure chests. Continue along the curving path until you past 2 more treasure chests and arrive beside O'aka and a Save Sphere. Curve with the wall north to enter the area that Spherimorph was or is located. If you haven't defeated him yet, do so now, and then go towards the area you fought and find Jecht's first Sphere in the water.

Jecht's Sphere 2

Return to Besaid Island by way of airship. Once there, go up the long and winding path all the way to Besaid Village. Once there, head straight to the temple. But before you go inside, turn right (east) just before the first steps between the ground and the temple. Keep going until you find the Sphere.

Jecht Sphere 3

Once again, to get this Sphere, use the airship to get to Besaid Island, and then head up the boarded dock and into the ship, SS Liki. Wander around until you reach the area where you see two kids running around a pole in the foreground. Go to the door (NOT THE STEPS), and enter. You'll see this Sphere lying on the floor.

Jecht Sphere 4

One of the easier Spheres to get, get to Luca Stadium by using the airship. Once you arriv, go up the stairs to the right and go down the stairs to a locker room. You'll find the Sphere in the upper-right hand corner.

Jecht Sphere 5

If possible, get to the Oldroad (the bottom path) from the airship's landing spot at the Mi'ihen Highroad. If not, run through the Newroad (preferrably on a chocobo to cut down time and battles) to the station, then do about a 250 turn and go down that path, into the Oldroad. Keep riding until the camera switches to a bird's eye view. You should see the Sphere in the southwest corner.

Auron's Sphere

Well, this is the most challenging of all the Spheres to achieve. Return to the Mi'ihen Highroad by way of airship, and then rent a chocobo if possible to cut down on battles and time, since you'll have plenty of those soon enough. Ride it all the way to the station, dismount, and then pass through. Once there, stay to the western (left) wall to the first breaking and enter it. Then curve your way through the valley clear to the other side and enter the next area, the Precipice. Hug the eastern (right) wall all the way to the back, where you'll find another elevator-like rock structure. Activate it with X, and then turn on the upper level in the direction that you first entered the Precipice. Keep walking past the Save Sphere until you see a small ledge-like structure. On it you'll find Auron's Sphere.

Jecht Sphere 6

Another one of the easier ones, use the airship to go the Moonflow wharf. A little below center screen after you land, and close to the right edge of the screen, you'll see a small green Sphere in front of a red curtain. It may take you a while to find it, but you should be able to eventually.

Jecht Sphere 7

Use the airship to get to the Agency near the Thunder Plains. Leave it and head south over to the plains, hugging the eastern (right) wall. After going a while, you'll see the Sphere.

Jecht Sphere 8

There are two ways to get to this Sphere. The first would be to head to the Thunder Plains. Head to the Ageny by way of airship, and then head south, all the way to the end of the Thunder Plains. In the next area, you'll enter Macalania Woods. You should see 2 children and their mother on the right. Go over towards them, and continue walking northeast (up-right). You'll see an island-like platform. On it is the Sphere.

Braska's Sphere

It's possible that you already have this Sphere, but just in case, here are the directions. Return to Mt. Gagazet, however you choose. Airship is probably the easiest, though. Once there, go past the gateway and up into the mountain. Continue up the zigzagging path until you find a short and narrow path heading north around a large rock. Follow it. At the end, you'll find Braska's Sphere.
